Rigging and using a compressor test cord to manually operate a compressor

One of the many things that can make a refrigerator warm up is the compressor is trying but failing to start. You may occasionally hear this type of noise from the back of the refrigerator (starts about 15 seconds in): This is the sound of your compressor trying, but failing miserably, to start. Best case scenario: Bad compressor start relay. Worst case scenario: open compressor start winding or seized compressor bearing == buy a new refrigerator. Question: How do you tell which is which?

LG refrigerator frosting up inside the freezer, but it's not a defrosting problem

This has been a long-time vexing problem in some LG refrigerator models. You'll also see this on Kenmore and GE refrigerators that were built by LG. The unit defrosts properly but builds up rime ice inside the freezer looking like there's an air leak, like from a bad door seal. But the door seals are good and no source of air leak can be found. Brother Durham found this tech memo that explains it and offers the cure: a redesigned evaporator fan motor. Here's the upgraded evaporator fan:

Troubleshooting tip for Whirlpool inverter-type microwave ovens with an F7 error code

The high voltage system in microwave ovens is used to power the magnetron and generate the microwave sound energy that cooks the food. This voltage is in the range of 2,000 vdc.

How to test and replace the ADC "Jazz" circuit board in Maytag and Amana refrigerators

The "Jazz" control board is what Whirlpool (makers of Amana and Maytag appliances) calls the Adaptive Defrost Control (ADC) board used in some models of french door and bottom-mount Maytag and Amana refrigerators. You can identify the Jazz control board by the two, single-digit digital displays for the freezer and fresh food temperature adjustment that are located at the top of the fresh food compartment. These Jazz boards fail pretty frequently. The two most common failure modes on these boards

If you're dealing with a Whirlpool Duet Sport front load washer (also sold under the Maytag and Kenmore brands) that just beeps when you press the start button but doesn't lock the door or run, it can be tricky to figure what the problem is. The prime suspects are: CCU (central control unit), MCU (motor control unit), and the door latch assembly. Academy Fellow Trying to help offers this tip for checking the MCU to determine whether it's the cause of the problem or not. If it checks good, you ha
