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. There are two ways of producing this high voltage. The older, conventional way is using a high voltage transformer, capacitor and rectifier.

Using the Tech Sheet Schematic to Root Out Appliance Gremlins

We all love those jobs where, given the brand, model, and problem description, you walk into the house already knowing what the problem is. After you've worked as an appliance tech for a while, you start noting that every machine has weak points and particular failure patterns. Some failures become so well-known that the manufacturer will issue a service bulletin on it. But what about those jobs where it's not a clear case of plug n' chug, in other words, where you DON'T know exactly what part t

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

Troubleshooting technique for checking the MCU in a Whirlpool Duet Sport washer

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

9 Ways to Beat Odor Problems in Modern High-Efficiency Front Load and Top Load Washers

1. Use Only HE (High Efficiency) Detergent And no, using a smaller quantity of conventional detergent is not the same as using HE detergent, as explained below. HE detergents are not simply a concentrated formulation of the regular stuff.
