Question about Sharp R-510HW Microwave Oven

Sharp Carousel Convection Microwave R-9H56 suddenly stops heating

I have a Sharp Carousel Convection Microwave R-9H56. The microwave works fine. The problem is the convection. You set it to pre-heat and it goes through the motions like it is preheating ie. carousel rotating, light on, making noise like it is working, but it takes forever. Eventually it suddenly stops (makes no sound like it has turned itself off). The display is static, displaying the temperature I was trying to heat it to and if you feel inside the oven it is stone cold (hasn't heated at all although it says it is preheating for so long). Another problem is it doesn't do it all the time. 50% of the time it works fine then next thing it won't. Taken it to be repaired twice. Had the thermostat replaced but still doing the same thing. Repairers cannot find problem. Help please. I really don't want to replace it as I love this oven.

Built-in Sharp Carousel II Microwave Convection Oven died.

There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

The carousel in our Sharp Microwave/Convection Oven suddenly stopped turning. Nothing seems to be blocking it--it whirls around when I push it. Any ideas?

Got someone to come look at it, and the motor for the turntable has burned out! We're ordering the part!
Thank you!

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.

Check that the plastic connector from your motor to the turn table is not broken , mine broke and it took weeks to solve the problem. Try rotating the part that protrude into the oven. If you can turn it by hand it is broken, lucky cheap to replace
