Sharp microwave stopped working


Is it totally dead? No display? Or just does not cook? If it made an unusual noise before it 'died' something probably shorted out.... You need an ohm meter to troubleshoot. If the fuse is open, switches and HV circuit need to be checked before replacing fuse. Sometimes on the convection Microwaves (not just Sharp) the fuse will 'rust' and open rather than blow. Or the fuse holder can over heat and fail.

Microwave not heating up


Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

PROBLEM WITH SHARP R-1874TF CONVECTION OVEN


sometimes an over heat will shut down the oven for a little bit but lets look at other things
i dont believe the board to be bad but i do believe the heating element inside is fried or a wire got fried by heat
if you know how to use ohm tester i would check heating element and wireing first
then try to see if the timer gave out

Microwave does not cook


The magnetron should have a thermostat or some other kind of heat protection device on it, but if it is activated, it will open up the power line, making the oven truly dead until it cools down.

So if it's dead, it may be a fuse or a thermal cutout / thermostat.

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 connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

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, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk
