After working on countless fridges with door closing problems in my refurbished store as well as outside repairs, I usually can get them to close without having to buy new door closers or hinges...
Amanas have been the most problematic of them all but there are several things you can try before buying new parts....

this is stream of consciousness so not in any particular order...do the easiest ones first

1) make sure the doors are aligned ....adjust the top hinges so the doors do not touch when closing....you have to find the proper angle

2) Soften the gasket with a steamer or hot water to make it pliable...don't forget to check the very bottom of the fridge

3) try adding a bit of food grade oil/grease on the right hand side of the fridge where the fridge gasket "rides" against it. There have been some discussion about the oil's effect on plastic gaskets....I have never experienced this problem....it may degrade the plastic after many many years.

4) make sure that any light switch that is pressed by the door when closing is at a proper angle to the door and does not stick

5) Adjust the fridge feet or wheels so that there is a slight incline on the fridge to enable gravity to assist in closing. This is proper for older non bottom freezer fridges.

6) Sometimes doors can get bent and many manuals advise slightly bending them back in alignment so that the top and bottom gasket hits the fridge at the same time.

7) adding a washer to the bottom hinge pin can slightly raise the fridge door and make closing easier

8) make sure there are no shelves out of place. Some fridge manual advise that certain door racks not be placed to where it hits food or drawers inside the fridge cabinet

9) The sneakiest one of them all and has caused be much consternation in the past is this: there is a metal piece attached to the door near the bottom hinge. It is there for cosmetic purposes to hide the hinge. Sometimes they get bent and causes the door not to close as easily as it should. You can remove it or bend it out of the way if you find that it hits the bottom of the fridge.

10) Make sure your gaskets and area where the gaskets seal on the fridge are clean and dirt free.

If none of the above works, you may need to get another door closer for the bottom hinge.

I noticed something on a LG dryer the other day. It was stacked, so I ordered parts and scheduled it with a helper. We took it down and tore it apart to install new rollers, belt, and pulley, The left side roller on the front bulkhead was totally destroyed. I replaced it with the shaft/pulley assembly and just the rollers on the other 3, cleaned and lubed of course. We put it together and tested it. It had a pretty solid drum seam thump when running.

We took it back apart and I found the drum did not touch the right front roller at all, maybe 3/8" or more gap. When I checked the panel I noticed there are 2 holes in the area of that rollers shaft location. The dryer was kinda toasted inside so there was a clear mark where the shaft was mounted, so we are certain the new shaft was in the same location the factory had used. I move the shaft to the other hole and the dryer ran smooth and quiet.

I wonder how often the factory uses the wrong hole, and this might be causing the cracked drums. In the wrong position, that roller does nothing, and the left hand roller bears all the weight in the front. The excess load on a single point working on that seam could be causing the cracking, at least in some cases.

Service Pointer
W10398386

Serial Numbers: F032 to F105

Customer Concern:
Dishwasher stops approximately 10 minutes into the cycle, “cancel drains” and goes directly to standby mode (off).

Cause:
Testing has determined that cycle stopping may result from a software error that can cause a false error code that cancels the cycle. Techs will see a 6-1 error code recorded in service diagnostics. This issue is very sporadic, and is affected by the location of the household and region of the country. Other conditions that may also cause this “cancel drain” cycle are: siphoning through the drain hose, severe sudsing, and debris in the sump.

Correction:
If the customer experiences a “cancel drain” issue, first check the following:
1. Make sure the dishwasher is installed according to installation instructions provided with the unit.
2. Check for water siphoning out through the drain hose. Ensure that the drain hose end termination point is above the water level in the tub. The drain loop attached to the side of the tub is not sufficient to prevent siphoning.
3. Check for severe sudsing or a malfunctioning Rinse Aid dispenser.
4. Check for locked rotor in wash pump.
5. Check for and remove debris in the bottom of the sump/chopper area.
6. Check for water supply and proper water level in the dishwasher.
7. If all the above checks are OK, then the control will need to be replaced with one that has the upgraded software designed to handle any additional power variation. See chart below for part numbers.  Testing has determined that cycle stopping may result from a software error that can cause a false error code that cancels the cycle.

GE Wall Oven: Display says "BAKE" but relays won't engage.

From our tech support conversation:
Tech Support: Is the door closed or open?
Tech: Closed.

.... long conversation with measurements etc ...

Tech Support: I'd like to verify the functionality of the plunger switch on the door. Can you locate it?
Tech: Yes, that's what I'm holding in to "close the door".

.... Ka-Ching! ... Nooo!!!

Tech Support: Please physically close the door and try again.
Tech: The oven is heating!


TIME SAVING TIP ABOUT GE WALL OVEN:

If the control board thinks the door is open it prevents the heating element relays from engaging.
This is completely determined by the state of the 2 micro-switches in the LATCH MECHANISM.
(To cook switch #2 (top) MUST BE CLOSED, switch #1 (bottom) MUST BE OPEN)
The oven controller DOES NOT SENSE the PLUNGER switch!

Remember this to save wild geese.

Control codes are particular to model. C0-C4. Your model is a C1 control. With unit turned off and fascia removed and module exposed, there are six buttons. Ignore the first button under display and label remaining buttons from left to right S1 S2 S3 S4 and S5. The leds above each button label L1 L2 L3 L4 and L5. Enter coding mode as follows:

Press and hold buttons S2 S3 S4 and S5 simultaneously, then turn dishwasher on using on/off switch. When in coding mode leds L2 L3 L4 and L5 will be blinking.

Release buttons S2 S3 S4 and S5 to view control coding in display. To change control coding, press button S2 as needed to scroll through codes. Your model is C1 or 21.

Turn dishwasher off to save control coding and exit mode. Reinstall control to console. Reinstall fascia. Check operation.

new grillefan has increased insulation.

And as anyone who's spent any time searching this site knows, there's gold in them thar old topics!

Be careful.. I've had a bad mag throw the same error, I would check mag for shorts and continuity first before ordering inverter board, high limit t-stat on cavity or mag could cause dead condition (no display) although I don't think those reset.

As JJ Surfer just said: Also check magnetron terminals to ground. After replacing the inverter and control board, I've found a shorted mag will also give you this F-7 error code, indicated by pulsing power to the mag just before the error code is displayed...

Yes, there is a 3 wire blue harness that runs from the CCU (Central Control Unit) to the MCU (Motor Control Unit) I believe it is the M3 connector. Unplug that connector at either end and let it hang. Now hit start, if the unit locks the door and acts like it is going to take off on it's little merry way, you have a bad motor control board. Chances are with this disconected after a minute or so a code will pop, but you will already have your answer. At the moment of start the CCU looks for two signals, door lock and motor control. If it does not see what it likes it tripple beeps. Removing the harness eliminates the bad signal. It will lock the door now and sit there looking for the MCU signal. No signal is better than a bad signal! Make sure you ohm your motor to verify it is not shorted and the source of the blown board though!

Old tech trick for checking CCU's was to unplug unit and plug back in.  If you hear a click from the CCU then the CCU was usually ok.  But I think these new CCU's are onto that trick.  Still researching that switch at access panel.  I don't know if it would cause a problem but it has attracted my attention.  Will advise.

After replacing evaporator fan and having the main board rebuilt ... the new fan wouldn't run. Well it turns out that the new fan comes with a new wire harness BUT it only applies to certain models. It swaps some wires around and if you install it on the wrong model the evaporator fan doesn't get power!!! It looks just like the orignal (unless you look closely at the pinout). It seems the fan doesn't ship with the WP instruction sheet. Fan p/n 8201589, board p/n 2252159 and brothers, jumper harness p/n 2221077.

This has got to have caused a lot of head bangin' ! ??

Here's the instruction sheet. Sorry it's a png. Site didn't let me attach the pdf.

I'm reminded of one time, a fellow tech and myself were at the shop.  He was working on a large countertop microwave and I was down the hall in the front office.  We could see each other and were carrying on a conversation, I forget about what.  I'm absolutely positive he had a few fillings in his mouth because as he was looking and talking to me his hand must have touched the high voltage diode or capacitor, discharging it.  I kid you not sparks flew out of his open mouth!  Being the trained and responsible guy I am I immediately fell to the floor, laughing my ass off.  I eventually recovered and asked him if was ok and he said yes, just scared the hell out of him.  I said, "Man, did you see sparks fly out of your mouth?"  He said no, he must have missed that.  Needless to say we both found new respect for microwaves and the awesome, dangerous, and sometimes hilarious power of the high voltage capacitor.

New variable speed inverter motors no longer
require the in-line fuse. When replacing an
older Hydrowave inverter motor with the new
inverter motor, the in-line fuse must be
removed from the washer harness. Failure to
remove this fuse link will cause the fuse link to
fail due to the higher inrush current of the new
motor design.

Replacement motors will include a jumper wire
and 2 wire splices to remove the in-line fuse.

You're probably going to find the evaporator coil in the freezer choked in with frost, in which case, the problem is almost always the infamous Jazz Control Board.  

There's a tech sheet in the toe grill that tells how to put the board in diagnostic mode for various tests.  But the most common failures with this board are 1) failing to initiate defrost and 2) keeping compressor running during defrost.  Both result in a frosted up evaporator coil.  

Put the unit into forced defrost.  If the defrost heater fires up, that means the defrost heater and limiter are good.  Then go ahead and replace the Jazz Board.  

Here's my video showing how to do the diagnostic dance:

The Frigidaire dryer control board "runs home to mama" with the E68 fault code.  It's the only fault code listed and the only one it knows.  It indicates stuck button as Brother Reg advised.  I've never found a stuck button, usually a bad board.  Did have a Gallery dryer the other day with control board and interface.  Threw an E68 at me so I ordered the main control board to have when going out.  Turned out to be the interface.  RATFARTS!!!  P/N for your board is 134523200.

Quick way to check evaporator:  With compressor running drain the water from the reservoir by removing bottom cap. Let run for a couple of minutes and check for slight frost on evaporator plate, touch top of plate with wet finger-should stick.  If not cold, turn unit off and listen for a hissing noise from evaporator.  Not cold and hissing-bad evap.  Would replace compressor as well for moisture contamination.

Sometimes a shorted fan motor can give you that same scenario. You can try unplugging j2 fan connector and see if the compressor comes on. If it does then you need to just determine which motor is shorted. I've only this happen to me once and it was the evap motor.

If you do a lot of GE fridge repairs, you may benefit by getting a diagnostic aid shown in the following video. It is, in essence, nothing but a control panel that you can use and will bypass the one in your fridge,  whether it is a similar panel, knobs or lcd screen control found at the dispenser. With such a panel, if you connect it and everything works, then you will be certain you have a bad control panel.  

btw, the part numbers needed for the aid have been changed. Instead of the three parts mentioned in the video, you need two WR55X10390 (interface and touch panel kit) and WX05X14999 ( wire harness). I got one a few weeks ago and it paid for itself in a few days.

ps you  can make one of these by removing a 5  key control interface from an otherwise dead GE and then purchase the harness.

Looking at the parts breakdown for that model, it looks to me like the correct maintenance kit for your dryer is this one
http://www.repairclinic.com/PartDetail/Maintenance-Kit/5304457724/1198622

Notice in the picture that the upper felt does not have the three plastic glides. That's because the plastic glide on your dryer is attached to the drum, it is the newer design.

The 5304461262 mentioned above is for the older design, with no plastic glide on the front of the drum.
Another thing worth noting is that this is a GE brand dryer but it is built by Frigidaire. The part #'s for the kits are Frigidaire numbers. You won't find them on the parts breakdown for a GE.

Knowing how parts interchange is one way us professionals can save our customers, and our fellow forum members, some dough.

BTW... gas coils... Whirlpool, GE, an Frigidaire all have part numbers for exactly the same part. Guess which one is Generally most Expensive

You can also verify by doing the test the Brother Kurtius prescribed, reprinted here for your viewing pleasure:

1. Remove receiver board (right side) and insert wire into plug in black/black-white wire locations . This effectively bypasses the optics for test purposes. if you have no black/blk-white wires in the plug don’t panic, just chose the two wires beside the blank hole, not on the end.
2. test for voltage at the 4 wire harness plug, black to white and black to green…should have 120vac in both places. if not, inline fuse is open or wire is broken or separated in the liner. very bad and prolly not repairable (the broken wire not the fuse).
3. if voltage is present, hookup i/m and test at the points on the motor module head previously noted L and N…should have 120vac.
4. if voltage is present, install jumper between test points T and H…this should start the icemaker on a rotation if all the above outlined conditions are true. if it doesn’t, the motor on the module is bad. if it does start, reinstall i/m and wait till it fills and parks. remove jumpers and reinstall optics receiver. icemaker should work…if not, we have proven the icemaker assembly is good and the optics must be at fault, regardless of whether the light flashes are checking good or not.

If the board checks bad by this method, it's slam-dunk dead.

What would you like to talk about? Other NON-APPLIANCE REPAIR problem

Talk to the Samurai: Hello Samurai,
It seems I have that "infamous and failure-prone adaptive defrost control board" for Jenn-Air JCD2389GEW as pictured here on your website. It has the same numbers #P19-399# SIEBE APPLIANCE CONTROLS 1996. It also has various other numbers such as MAYT78245.001, ECD#100-01103-01, 20R1448-00, 60727Q, AJW4212, JWIFSN, 062707367, and also THAILAND. I would like to know which part I would need to replace this part. My "original" still keeps the freezer and ice-maker working properly, fans are turning, and refrigerator section is cool, although probably not cool enough, but it does not defrost itself. I have to manually defrost every morning and evening to keep it going. There are so many of these Part #61005988 offered for sale at a great variety of pricing, so I don't know which to choose, as they all claim to be #61005988. I contacted Jenn-Air and was told that mine was Part #61003990. I tried ordering an inexpensive generic part #61003990/#61005988, but that didn't function at all, and did not operate my fridge at all; total waste of time and effort. I had to reinstall my original part; I have no difficulty installing the part, as I know how to do it, and I am proficient at it! I guess I need an "original", but I don't know where to obtain one. Perhaps a more expensive OEM part #61005988 would work, but now I'm almost afraid to try again. The part I tried had a number on it #MA7700112254-TH#. I assume that the "TH" stands for Thailand. It certainly DIDN'T have the #61003990 or #61005988 on it. I DON’T WANT THAT PART AGAIN! It is confusing to have all these products available with the same part number and a wide variety of different prices. I've seen so-called brand new items like this for as low as $19.95. I would appreciate your input. I need a "working" part, not a make-believe part, to waste my time and effort. WHY are there so many different prices on this item???? DOES the price affect the “workability” of the product???? WHICH PART NUMBER SHOULD I ASK FOR???? I look forward to your response. THANK YOU MOST KINDLY,
Regards, Mari

here's the short version:

- Remove everything from the tub front and back.  (Shocks, hoses, pressure hose, bottom hose, ground wires, drive belt, motor, pulley - but leave the bellow still attached, just disconnect it from the washer front.)
- Pull the weights off front and back to make it lighter.  (Tub's are about 53 lbs with all weights removed.)
- Lift the tub out the back (you might disconnect the top brace that holds the valves and lift it up to make it easier.)
- With a Sharpie, mark where the clips are on both halves.
- Remove all the clips and separate out.
- If you are doing this because of a bad bearing, you have to replace the rear tub as well.  
- Don't forget to gob up the new bearing with the supplied grease ... and don't forget the new gasket that goes between the tubs
- Put the halves back together - you may have to pinch them together with Channel Locs to get the first couple of clips back in place
- Reassemble
- Double check that all hoses have been connected before testing.

yes it is the transformer

the noise is a loose winding and will never stop the microwave from working or make it unsafe in any way

if you replace the transformer the noise will go away

Pretty easy to troubleshoot with a multimeter at the inverter board. On the leftmost connector, using wht/red for your neutral to the meter, you should have 120vac on the red/blk wire and the orn wire (gray on some models). Still using the wht/red for neutral, on the rightmost connector (control voltages from timer) you should get 120vac on these wires depending on mode of operation.

High speed agitate, blu and vio/wht
Low speed agitate, wht and vio/wht
High speed spin, blu and red
Low speed spin, wht and red

If you are getting the appropriate voltages for a particular mode and the motor isn't working, the motor is faulty or you have the wrong one. There are about 5 different versions of this motor/inverter and they are not interchangeable. On washers that use an electronic control board versus a timer, the control voltages are low DC levels, not line voltage. The inverter has it's own microprocessor, memory and program algorithm for operating the motor. The control voltages from the timer simply tell it what mode to begin operating in. If you are not getting the proper voltages from the timer, the timer could be faulty or you may have a faulty pressure switch or wiring/connection problem. There should be a wiring diagram behind the control panel.

this may apply:

Freezer Drawer (some models)
1. Open drawer to fully open position.
2. Remove upper and lower basket.
3. Remove screws one in each rail marked on side of rail.
4. Lift front of drawer up and out to remove drawer.
5. Set drawer on a padded surface to prevent damage to finish.

The early stages of a motor failure exhibits the famous 60 cycle hum.  120 volts is supplied to the motor; if any of the windings begin to short; there is not enough induction, the rotor of the motor stalls and eventually locks (locked rotor amps) draws excessive current and trips the internal/external overload on the motor. Before this occurs, if a winding in the motor is shorting, you will hear a buzzing noise which is the 60 cycle frequency of the 120 volt supply indicating (perhaps) a failing motor.

I go out on a DOTT type whirlpool dryer, order says it won't finish cycle. He leads me to the laundry room and I find the thing completely dismantled. He said he hired a buddy to fix it, but he couldn't figure it out. He had the front off, the burner tube out, he bent and broke the clips to force off the kick panel. he removed the rear bulkhead, he took the front off with out removing the blower, he even took the screws out of the door. He failed to gain access to the console, lots of bending and pry marks but he never found the clips to open it up.

The only wrong with the machine was a blown thermal fuse.

It took 3 min to find the problem, and 90 min to rebuild the dryer around the new thermal fuse.

What a tool.

When the electromagnet pulls the plunger down, it doesn't close the drain flapper all the way, (only about 3/4 of the way closed), then the water pressure hits the flapper and holds it sealed against the spray arm outlet so the water goes out the drain.

When the water pressure hits the drain flapper and opens it the rest of the way it takes the load off the solenoid. The solenoid is only energized for about 30 seconds and if it finishes draining before the the timer turns off power to the drain solenoid then the return springs will pull pressure against the magnetic force of the solenoid and can cause the buzzing noise.

I just wanted to share a part number I recently received from Whirlpool after much arguing and tons of recalls for this issue.  I work in Northern VA area, and we have ran a lot of builder calls around here with the top shelf freezing on the SXS for the last 2 years.  Whirlpool made us change sensors, pcb, dampers, blame the customer for blocking the back shelves, applying permgum inside damper area, etc. There haven't been many techs on our team that have run into this as much as the few of us stuck running new home calls. I found out they made a new damper design to fix this issue, but did not have a part# for a long time. I was to the point of telling the customer not to call us back for this issue and contact their builder and Whirlpool, so they could get this new damper. Well the part# for this new damper is W10572852. I hope this helps anyone that may run into this issue. I do not have specific model numbers, but it has mainly been the SXS manufactured in the last couple years with the ice makers located on the freezer door.

This sensor dry should not be confused with a temperature sensor, the sensor bars measure moisture and the temperature sensor “thermistor” measures temperature.  Sensor dry uses nothing more than two metal bars inside the edge of the drum. These bars do not go bad unless they are physically damaged however it is always a good practice to clean them whenever servicing using some rubbing alcohol, especially when the unit gets older. Never use sand paper or other abrasive methods.

At the start of the cycle an estimated time will be displayed as the Main PCB monitors the sensor circuit for 3 minute after the 3 minutes the estimated time can increase decrease, stay the same or advance to off based upon the moisture detected. The unit will do this assessment multiple times during the auto cycle and can adjust the estimated time as needed.

Diagnostic Procedure:

The sensor dry bars can be checked easily by
placing a coin across both bars and checking for
continuity.
Being more specific the resistance values are listed
below
Dry Clothes = Infinity
Wet Clothes = ~190 ohms ±10%

The sensor bars can be also tested in diagnostic mode. Place a slightly damp cloth in the dryer, start a normal cycle then press the Temp + Signal buttons for 3 seconds. When there are wet items being dried, data will add up (from 0 to 1200 and repeating) as the wet clothes touch the sensor bars. If the sensor bar value does not increase as wet items contact it the sensor is defective.

NOTE:  Select any Auto cycle without clothes hit start unit should run for 3-5 minutes and shut off.

Usage and  Customer Education:

Sensor Dry Mode automatically measures the moisture in the load and shuts the dryer off when the proper level of dryness is reached.
At the start of the cycle an estimated time will be displayed as the Main PCB monitors the sensor circuit for 3 minutes. After the 3 minutes the estimated time can increase, decrease, stay the same or advance to off based upon the moisture detected. The unit will sample moisture level multiple times during the auto cycle and can adjust the estimated time as needed.

The length of the dry time will be proportional to the size of the load as well as the moisture in the clothes.  However there are several factors that will effect dry time. These can be installation issues such as improper venting or a clogged lint filter. Another reason for clothes not being fully dried is the fabric itself. For example, towels or jeans are very thick and can contain some moisture even though the outward edge is dry. For best results always wash like items such as towels with towels jeans with jeans etc.  It is important that loads are large enough to make adequate contact with sensing bars for feature to work properly. The customer complaint for undersized loads would be “clothes not dry at end of cycle”. If consumer has the need to wash and dry just a few articles of clothing recommend using time dry for those loads.

NOTE: Always remember the time being displayed is an estimated time and can increase, decrease, stay the same or advance to off anytime during the cycle.

NOTE: Wrinkle Prevent  Feature will extend cycle for 90 minutes. Drum will tumble with no heat and lights in control panel will oscillate.
Wrinkle Prevent is often overlooked as possible cause for long dry times or dryer never shuts off..

I've had f2 errors where the problem was a thermal fuse. Usually I test probe and fuse (if there is one), and reset ecm if possible before I replace a board on any oven, regardless of manufacturer or error codes.

With regards to tech sheet writers, the following question and response was found on 85 % of their requirement exams...



The problem is, their examiners consider it the correct answer.

Bad model#, but:



Customer Concern: Dishwasher stops approximately 10 minutes into the cycle, “cancel drains” and goes directly to standby mode (off).

Cause: Testing has determined that cycle stopping may result from a software error that can cause a false error code that cancels the cycle. Techs will see a 6-1 error code recorded in service diagnostics. This issue is very sporadic, and is affected by the location of the household and region of the country. Other conditions that may also cause this “cancel drain” cycle are: siphoning through the drain hose, severe sudsing, and debris in the sump.

Correction:
If the customer experiences a “cancel drain” issue, first check the following:
1. Make sure the dishwasher is installed according to installation instructions provided with the unit.
2. Check for water siphoning out through the drain hose. Ensure that the drain hose end termination point is above the water level in the tub. The drain loop attached to the side of the tub is not sufficient to prevent siphoning.
3. Check for severe sudsing or a malfunctioning Rinse Aid dispenser.
4. Check for locked rotor in wash pump.
5. Check for and remove debris in the bottom of the sump/chopper area.
6. Check for water supply and proper water level in the dishwasher.
7. If all the above checks are OK, then the control will need to be replaced with one that has the upgraded software designed to handle any additional power variation.

Verify new board is Control Board W10380685, the upgraded part.
