Re: my welbit microwave model mr755t not working

I would suspect a bad door switch. Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya:

I believe it's been a few years since these ovens were made and doubt if you can buy a whole new one. Not sure about the wattage.

My ge microwave spacemaker profile model # JVM1860BF001 stopped while in use. Interior light, clock and timer work. Door vent opens. turntable doesn't work. Won't heat.

check the breaker, or check if the wall socket works. If there is power, then you need to take it for service. There are no user service options for microwaves as they are so dangerous for both super high voltage and also microwave emission. Some models do have a pull fuse on the rear, so check for that first.

Microwave light and clock work but no heat

Could be one of the three door switches. If the fan turns on when cooking and no heat then the magnetron is bad. Most problems are the switches

Microwave has power, but nothing works.

The door switches are more than likely the problem, one or two will need to be replaced, I recommend a professional.

Emerson MW9111 will not heat- all timers & clock work

Normally when you take the cover off, the fuse will be on the right of the oven on the circuit board.
