When ever I scrap a microwave I save the little micro switches that are on the door latch. These are the interlock switches and they can go bad just from opening the door before the timer stops.
Tuesday I picked up 2 in the trash
1) a nice SS GE Profile mod.#JE2160SF03
2) an older Tappan in good shape mod.#TMS134T1G1
A quick check for continuity with the meter and I changed 1 switch in each microwave from a stash of switches I have from other microwaves that where scrapped.
A craigslist add or flea market/garage sale.
the GE I'll ask $50.00 & take $40.00
the Tappan I'll ask $35.00 & take $25.00.
It only takes 10-20 min to check and change these switches. Most of the microwaves I've checked one of these interlock switches are bad.
They can blow the internal fuse as soon as power is applied to it or the microwave timer will count down but not heat up.
Hope this helps someone make a little more than scrap value.
