@wdormann Had this issue with a air purifier. The warranty had just expired and it died. tried doing my best to look at it and didn't really turn up much (not an electrician or very experienced with that sort at the time). But since I wasn't going to put myself through that shenanigans again I built myself a Corsi–Rosenthal Box instead. I kept the old parts around and after finally getting to the clean up old junk stage noticed that one of the capacitors on the power supply board had popped. probably could've fixed it for 5 cents or so. But I had already disassembled it for e-waste disposal >.<
