How I Fixed a Dead Whirlpool Washer for $23 Instead of Paying $300

Part-time appliance fixer-upper here. I've done a few brands.

One thing with the newer models, especially Samsungs and the like, is they started using potting compounds to cover their circuit boards (within the plastic casing!), making simple fixes like replacing a voltage regulator or a capacitor essentially impossible. Yes, you can dig through the thing, but you're likely to slice through a trace if you don't slice your hand first. I unfortunately have a stack of these and I don't know what to do with them. [1]

Slightly older models, mid to late 2010s and earlier, are often easier to deal with because their circuitry is based more on simple analog controls for which a replacement part is not only widely available, but is cheap and can sometimes be improvised if needed, than on digital boards. I'm thinking of fridges which use a rheostat for the thermostat control. If one was so inclined and could absolutely not find a replacement, a bespoke set of resistors with a clip to choose termination point could be used instead.

If someone does want to get into this sort of thing, get something that already has a service manual + plenty of youtube videos. "Spare Parts" companies have tons of videos on how to do things, but they usually stop at probing and debugging circuit boards. You have service manuals that -do- contain, on the rare occasion, the schematics. But it's best to go with appliances that have incredibly simple, analog and discrete component systems rather than a plethor […]
