#318154 MFI2266AEB High voltage board fails repeatedly after 2 to 4 weeks

Posted by Samurai Appliance Repair Man on Today, 11:50 AM

... Frigidaire recently with a bad touchpad, and some of it would work while other parts would just beep like it was locked out.

 

Very common failure presentation for any appliance with a membrane pad. It's a common algorithm used in the control boards to lock out when a stuck keypad is detected. Safety, liability, etc.

Definition of insanity: keep doing the same thing and expecting different results. 

 

Given the number of times you've replaced both boards, we can confidently conclude that the problem is NOT either of the boards. This is when you starting looking for other possible causes. 

 

Sounds like a stuck keypad to me. Given the use pattern (long, daily button presses) and the failure presentation, it sounds like the board is detecting a keypad held in too long. Looking at the parts diagram, there's a membrane touchpad on the dispenser. These are famous for stuck keypad failures in all types of appliances: refrigerators, ranges, dishwashers, etc. Just an inherent weakness with that technology. 

 

One way to test this is to simply disconnect/reconnect the ribbon pad connector for the touchpad the next time the failure occurs. This may reset the board. 

 

You can also test each pad with your ohm meter while you press it. 

 

I have also had good success proving a bad touchpad by simply dismounting the touchpad during the failure condition, still connected electrically, and gently flexing the touchpad. Many times, this will unstick the bad keypad. 

 

Another trick with these is to use a hairdryer to gently heat the touchpad. This is another way of inducing a physical change in the touchpad to unstick the bad keypad.

#318091 GE WSSH300 stopped mid cycle, wont drain

Rule of thumb for these machines: for any error code in the 40's, replace the door latch assembly.

Posted by Samurai Appliance Repair Man on Yesterday, 07:43 AM

Make sure the thermocouple is engulfed in the top third of the pilot flame or it won't get hot enough to make the valve open. Can also use your Bic lighter on it to see if that makes a difference. If the valve still doesn't open, then replace it.




#317902 #LAT9416AAE MAYTAG WASHER

Posted by Samurai Appliance Repair Man on 16 April 2015 - 12:42 AM

From the timing chart, it looks like the only difference between the Permanent Press and Regular cycle is the length of the agitation period. Both still use the regular run winding on the motor. The low speed winding on the motor is only energized in the Delicate cycle (cam 8, contacts 16 to 31). 

 

Since there's no separate cycle selection switch shown on the schematic, these selections are made on the timer itself. It's been a while since I worked on one of these old war horses, but I think I remember it this way. That being the case, you're looking at a flakey timer, specifically flakey contacts 16 and 32 on cam 6.

Sorry I missed this one, Bryan, but big brownie points for coming back and telling us how this one turned out. Good info!

#317560 kenmore ref Model 106.9530210 strange electrical after moving it

Posted by Samurai Appliance Repair Man on 11 April 2015 - 05:18 AM

Actually, looking at his first picture, ground and line (the red-black wire) are jumped together using a piggy back terminal on the ground spade of the fan motor. This will blow the breaker whenever the fan comes on in normal run mode.


#317527 BBI20TPSW bottom mount. Evap fan motor proble.

Posted by Samurai Appliance Repair Man on 10 April 2015 - 03:01 PM

No, but it would have told him that the fan wasn't the problem.  Then he could have focused elsewhere. 

 

True but only IF he had the tech sheet with him, which I don't think he did. Or, if he did, he didn't look at the schematic to see that that would be the case.

 

Moral of the Story: Always Pre-diagnose!

I'll bite.

The fan doesn't run because there is no return path back to neutral through the fan. 

 

Exactly! In fact, looking at your markup, you could make both lines to the evaporator red because they are Electrically Equivalent Points (EEPs). 

 

Both sides of the evaporator fan are being supplied with line voltage. This means there is no potential difference across the fan motor and hence no possibility for current flow through the motor. Voltage drives current. You could have one million volts on each side of the evap fan motor and it still won't run (might explode but it wouldn't run).

Have you personally seen this reported temperature problem? If not, then the technique I use for elusive temperature complaints is the almighty data logger...

Posted by Samurai Appliance Repair Man on 09 April 2015 - 10:38 PM

If the compressor continues to blow relays, a 3 in 1 maybe a reasonable option. 

 

As long as the customer understands and accepts that this is not a permanent fix because the compressor is on borrowed time. Gives them enough time to do some leisurely shopping for a new fridge (as opposed to panic buying). 




#317475 What's the trick to getting a stuck Cabrio agitator-less agitator out?

Posted by Samurai Appliance Repair Man on 09 April 2015 - 09:53 PM

You've obviously never hefted one of those bad boys. You grab that tub puller, wail on that agitator and watch with amazement and delight as the agitator shatters like cheap glass.


#317465 mdc2257hes, Maytag sxs fridge. HELP!

Posted by Samurai Appliance Repair Man on 09 April 2015 - 09:16 PM

That's mo' bettah.  Service manual and tech sheet are in the downloads section: http://appliantology...and-tech-sheet/

 

Put the jaz board into service mode and select the evap fan motor test. Then use your loading meter to test voltage from J1-6 to J2-8. If the meter doesn't light up, then the neutral is open. Maybe a bad jazz board out of the box or a wiring problem.  Verify you have 120vac from J1-1 to J1-6. All this is on the schematic.
