How to remove a stuck agitator from a washing machine

Posted by Samurai Appliance Repair Man , in Washing Machine Repair 04 December 2011 · 4,245 views

Methods to pop off agitator

2x4 method...the one we use
1 Fill the washer with hot water to cover the bottom half of the agitator

2Get a piece of strong rope about 58 inches long. Tie a knot the way you see it on the picture.

3 Place the rope around the agitator neck (sometimes looping under the bottom of agitator is best)

Posted Image

4 Get a 5 ft long piece of 2x4 and put a folded towel underneath it to protect the finish on the washer top.
Posted Image

5 Use the 2x4 as a lever. Putting pressure on the end of the piece of wood will lift the agitator out.

in the olden days we would loop 2 ropes under the agitator, connect the rope to each end of a 2x4 or broomstick. Stand on the machine and lift up like we were doing a clean and jerk

uh, huh...guys didn't think the old man had it in him, did ya now?. See what moving 'frigerators can do. But alas, we'll let you young ones get all puffy while we'll use our brains and the principal of leverage as depicted above or.......

bladder like device that lifts it out for ya

and even better, a home made agi remover thingy made using a unibar, some bent metal, a crescent wrench (or better yet, a drill driven socket)

How to disassemble an LG dryer to remove a sock or something stuck in the blower

Posted by Samurai Appliance Repair Man , in Dryer Repair 03 December 2011 · 5,508 views

Dryer powers up, you select a cycle and push start and the dryer hums for a coupla seconds and then goes quiet for a while. This usually indicates something is blocking the drum from rotating. A sock stuck in the blower would do it.

A quick test to see if you have a drum blockage problem is to simply open the door and try to turn the drum by hand. If you can't turn the drum manually, ain't no way that dinky motor in there is gonna turn it, ether! Can I hear an, "A-freakin-men?"

If you need to get inside the dryer to remove a sock stuck in the blower or some other rolling problem, Sublime Master john63 steps us over the rice paper without a single tear or wrinkle:

Unplug dryer

Looking at the rear of dryer---the TOP COVER has what looks like "hinges"

At each plastic "hinge"---there are 2 phillips-type screws---remove only the lower screws at each "hinge".

Grasp the TOP COVER and slide rear about 2 inches---lift off & remove.

Standing at the front of the dryer---remove the WATER DISPENSER TRAY (release tab is at the bottom of the drawer).

Remove the 2 phillips screws that are now visible with the WATER DISPENSER DRAWER removed.

At the right-hand side of the CONTROL PANEL---remove a single phillips screw from the corner (opposite side of panel).

Disconnect plugs/wires that are directly behind the *jog dial* of the CONTROL PANEL

Remove the CONTROL PANEL---a small flat screwdriver helps to unsnap the **tabs** that secure the CONTROL PANEL

With the CONTROL PANEL removed---remove the 5 screws which secure the entire FRONT PANEL/COVER of the dryer. These screws are located at the top of the front panel---and were not visible with the CONTROL PANEL installed.

Pull the FRONT PANEL towards you just enough to allow unplugging the DOOR SWITCH

Lift the entire FRONT PANEL an inch or so & remove

Remove the LINT FILTER & place it inside the Drum

Looking at the front of the dryer---you'll notice a DUCT HOUSING (silver)

Remove the 2 phillips screws from the DUCT & slide it down-and-away.

With a bright flashlight---examine the BLOWER HOUSING---remove any clothing/obstruction

Re-assemble in reverse order

Common parts that cause rolling problems when they go bad:

Drum Roller

Belt, Drive

Drive Motor

Blower Wheel

Idler Pulley

How to remove the agitator from an older model Maytag top-loading washer

Posted by Samurai Appliance Repair Man , in Washing Machine Repair 03 December 2011 · 1,652 views

The later-model Maytag Dependable Care washers had a little 1/4 screw at the base of the agitator that held it on to the drive shaft. On the older model units, the agitator was held on a bit differently. Academy Fellow Willie explains The Trick™ :

The older Maytag's don't have that 1/4" hex screw in the side of the agitator holding it on. They use a rubber o-ring style band around the agitator shaft that the agitator snaps down onto, it can be very difficult to remove the agitator on these machines without the use of a strap under the agitator looped over a 2x4 to pop the agitator off or the use of the "Agitamer Tool".

GE Refrigerator Appliantology: Dampers and Thermistors

Posted by Samurai Appliance Repair Man , in Refrigerator Repair 30 November 2011 · 2,015 views

This is the next in a series of posts I’m doing about the technology used in GE refrigerators. Understanding the basics of how these refrigerators work will give you a lot of troubleshooting insight when you’re trying to track down a problem.

For the previous post in this series on controlling and operating the fan motors in GE refrigerators, see this page.

This post gives useful tips and Fun Facts to Know and Tell for diagnosing the Damper Door and Thermistors.

Damper Door

The Damper Assembly has two motors: one to open the Damper Door and another to close it.

The Damper Door should always be either fully open or fully closed; if you ever see it in a halfway state, there’s a problem. Check it in diagnostic/self-test mode where you can run a test to open and close the damper door.


Thermistors are basically variable resistors whose resistance changes with temperature. They come in two flavors: Positive Temperature Coefficient (PTC) and Negative Temperature (NTC). In the PTC thermistors, the resistance increases with increasing temperature whereas in NTC thermistors, the resistance decreases as the temperature increases. All thermistors used in GE refrigerators are NTC.

Most of the side-by-side units will have four thermistors:
- attached to the evaporator coil
- freezer space
- beer section space
- damper

You can see a diagram showing thermistor locations in side-by-side units here ==> LINK

Units with the Custom Cool feature will have a fifth thermistor for the Custom Cool compartment. Lower end units will just have three thermistors.

In all units, the thermistor attached to the evaporator coil is the most troublesome.

There was a rash of problems with one of GE’s old thermistor suppliers a while back where they weren’t sealed properly so moisture got into ‘em and knocked ‘em out of calibration. More about that here ==> LINK

The refrigerator control has a self test for the thermistors, but it only tests if they’re open or closed. In real life, the thermistors rarely fail that way– usually they simply go out of calibration resulting in poor temperature control.

GE Refrigerator Appliantology: Fans, Evaporator and Condenser

Posted by Samurai Appliance Repair Man , in Refrigerator Repair 30 November 2011 · 1,755 views

This is the first in a series of posts I’m going to do about the technology used in GE refrigerators. Understanding the basics of how these refrigerators work will give you a lot of troubleshooting insight when you’re trying to track down a problem. This post explains how the fans in GE refrigerators are controlled and operated.

Like most other refrigerators, GE refrigerators have at least two fans:
- the evaporator (freezer) fan
- the condenser fan (the hot coil in the back, underneath the refrigerator)

Some up-line GE models may have an additional fan:
- in the beer section if it’s a dual evaporator unit
- in the Custom Cool® compartment, if so equipped

All fan motors used in current model GE refrigerators (includes Hotpoint brand) operate on 12 vdc. The motor speed is controlled using a technology called Pulse Width Modulation (PWM). Simple explanation of PWM: take a square wave and vary the width of the upper side of the pulses according to how fast you want the motor to turn- the longer the pulse, the faster the speed. For details on how PWM technology works, see this page ==> http://www.netrino.c...idth-Modulation

Currently, the condenser fan is single speed (although that’s gonna change in upcoming models) and the evaporator fan is multispeed.

Fan Wire Harness Color Code

- Yellow: PWM signal (input)
- Blue: Tachometer (output from motor)
- Red: +12 vdc supply (input)
- White: Common Ground! Can I hears an “A-freakin-men?”

The PWM wire on the fan motor harness is always the yellow wire– this is the wire that carries the signal telling the fan how fast to spin. Don’t bother trying to measure the voltage on the yellow wire with a conventional meter because the results will be meaningless.

Quick n’ Sleazy Fan Test

- White wire to the negative battery terminal
- Connect BOTH the Red and Yellow wires to the positive battery terminal.
Do not reverse the leads or you’ll blow out the sensitive electronics built into the motor assembly!

Quick Fan Diagnostic Test

- you should never hear the the fan making speed varying sounds in side-by-side units
- on top-mount units, you can sometimes hear the fan making pulsing noises

Fan Circuit on the Muthaboard

Some of the Muthaboards used in these boxes have resistors in the power circuit for the fans. These will be two resistors coming off the J2 plug on the board. If you’re looking straight at the board, the top resistor is for the evaporator fan and the bottom one for the condenser fan. They’re designed to burn out in case one of the fan motors shorts out. If this happens, you’ll need to replace BOTH the affected fan motor as well as the Muthaboard.
