We had one that did the same thing. my brother got so mad at it he put a wrench in it and turned it on. It didn't do anything to it. No power surge nothing. It acted as if I put a plate of food. Lighted up turned and even beeped when done. The wrench wasn't even hot. Now I do recommend this myself. But we went and got antoher one.
There is something in there that magnifys the power inside the mircowave and it sounds like its out.

That sounds like a door switch. Which switch is it? Top, middle, bottom?

Is your model number R1480? If not, please reply back with your model number so we can help you.

The door switches in model R1480 are:

QSW-MA110WRE0 top & bottom switches

FFS-BA016/KIT middle monitor switch with fuse (kit)

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

But the best place to order Sharp parts is Tritronics.

If none of this info helps you, please reply back with your brand and model number and let me know which part you need.

Microwave oven inoperative


When you enter the time then hit START, does the turntable motor come on? If not, then I would suspect the secondary interlock switch, its mount, or its wiring. If so, then it's hard to say, unless there was some miswiring somewhere. The original problem sounded like just a classic bad door switch. At this point I suspect the wires on one of them may not have been reconnected exactly where they were. It does matter. I would suspect the secondary interlock switch, which MAY have white/white and grey/grey wires attached. Also, one of the switch mounts may have a broken tab that makes the switch move so it's not getting activated. At our site, we have the service manual for the R1830, which is similar to the R1480-series. We have that plus *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
