SOURCE: 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 first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Then let us know if the hard reset does not fix it.

You may have a bad keypad.

When the unit is turned on it shoots flames from the roof of the unit WHY?


It sound like the antenna behind the plastic plate may be warped and touching the cavity. From my experience when they start shooting sparks it is time for a new microwave.

Looking at other answers below your question on the page that i am viewing anyways. It appears that Sharp convection microwaves or Sharp microwaves in general seem to have an ongoing problem of that sort. The solution is to replace the main circuit board.

Sharp carousel microwave convection oven keeps blowing fuse


The service manual is here:
http://www.microwavedisplay.com/r820bc_bk_bw_sm.pdf

You can get Sharp parts from Encompass here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
See http://www.microtechfactoryservice.com/cap_test.html

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
See: http://www.microtechfactoryservice.com/xformer.html

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

Sharp carousel convection/grill/microwave maybe R990


Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck .

Sharp Carousel Convection Oven. Model R-9H54.touch pad


It depends on what you mean by "a problem with the touch pad assembly".

If some or all keys do not respond, you would probably need a new keypad, but the key units for all Sharp R-9H-series models have been unavailable for a few years now.

These units did indeed last a long time.

Sorry I can't bring better news.
