GE Profile Microwave is blowing through door switches
I have a Profile microwave that’s about 10 years old. A couple of years ago it stopped working, and the problem turned out to be the door switch. (Surprise!) I replaced the switch, and everything was fine for about 6 months. They it stopped working again. Door switch again. Fixed. Good for about 6 months. Dead switch again. What’s going on?
I see two likely causes. 1) I’m buying $5 switches off Amazon instead of the $40 OEM switches from Sears Parts Direct. 2) There’s an issue with the microwave that’s causing it to melt switches. And melted they are. The bottom lead is consistently melting the plastic that supports it, leaving it twisted at a 45 degree angle. And it’s always the same switch.
Occam’s Razor says it’s that the switches are cheap, but before I go spend $40 for a tiny, unispired bit of plastic and metal, I thought it was worth asking the question. Anyone have experience with cheap switches dying or microwaves killing their switches repeatedly?
