How to fix a Samsung dual-evaporator refrigerator where the beer compartment keeps icing up

This fix is for the Samsung-built refrigerators (includes some GE's) with two evaporator coils: one in the freezer compartment and a second one in the beer compartment (most refrigerators just have a single evaporator coil in the freezer compartment). The problem here is that ice would be left in the condensate drain pan after defrost (see below) which would build up to a solid chunk of ice. Here's a clever, low-cost solution: Source: defrost failure samsung model RS2555SL

The Future of Appliance Repair: a Profession or an "Idiocracy"?

We have a lot of moving parts at play in the appliance repair industry today. Over the past couple of decades, appliance technology has become much more complicated, yet technician troubleshooting skills have eroded. This creates some uncertainty about the direction our industry is going.  Are we going to be a profession, filled with well-paid, highly-skilled technicians at the top of their game, or a semi-skilled trade, filled with low-paid parts changers who are essentially just the eyes

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:

Icemaker Wiring Info for Frigidaire Whirlpool and LG Refrigerators

Sometimes, you want to use an ice maker made from one manufacturer in a refrigerator made by a different manufacturer. The trick is knowing how to map out the wire harness so you can splice the wires into the harness in the right order and not pop the breaker or blow out the ice maker. Brother Reginald has prepared this nice table that lists wire cross reference info for Whirlpool, Frigidaire, and LG ice makers. Wire away! Source: How do I splice ice maker wires?

Samsung Dryer Troubleshooting and Electric Circuits Review

Many techs have trouble interpreting a schematic diagram and understanding how to use it for troubleshooting. In this webinar, held on March 29, 2019, we used a Samsung electric dryer and a GE double oven as case studies to review electric circuit principles and troubleshooting. Some of the topics we talked about: Neutral sensing in Samsung dryers: what that means, what it does, and how it affects troubleshooting Series and parallel circuits and how to identify them on a real-worl

How to Changeout a Shaft and Mode Shifter Assembly on a GE Top Loading Washer

The shaft and mode shifter assembly is used on the GE "Hydrowave" line of top loading washers. These washers has the motor with the inverter board mounted on top of it. The inverter board has an LED that flashes on and off according to an error condition or standby that it's reporting. See the table below: As you can see above, if the LED on the perverter board is flashes in a sequence of four flashes, this indicates a problem with the mode shifter circuit or mechanism.

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
