Home appliance repair is not a specialized job. Maybe you have some sort of memory about the Maytag repair man, but that is just branding, just like DeBeers with their diamond monopoly.

Home appliance repair is knowing the general layout of each major appliance, a bit of specialized knowledge on how to dismantle them without braking them, and which modules are responsible for which function, and finally knowing how to source the replacement parts and knowing which common items are best kept on hand for convenience.

Very few people are doing board level repair for appliances, especially when the replacemeent boards are typically very inexpensive for any modern machine (save for main boards and for induction plates in induction stoves, which are typically so expensive that it is smarter to replace the entire appliance rather than repair the broken module).
