SOURCE: R-4H84 Sharp Carousel II microwave oven stoped working

A microwave can be dead for many reasons.

The fuse is normally located on the floor of the chassis behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

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

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

SOURCE: Where is the light bulb in an old Sharp Carousel Microwave?

Microwave_svc's site is awesome! I was able to get all the help I needed for a similar Sharp Carousel microwave. My bulb was simply loose in the socket base causing intermittent bulb lighting. Microwave_svc's helpful links got me to the service manual and, along with a nice set of "tamper-proof" screw compatible TORX bits I bought at HarborFreight, I was easily able to get cover off, remove bulb socket, tighten bulb, re-install bulb socket, button unit back up, and, voila, the light now works without intermittent blinking. FIXYA!!!!

Many thanks to guru microwave_svc!!!!!!!

SOURCE: sharp carousel microwave doesn't spin

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

The best place to order Sharp parts is Tritronics. You can also call them at 866-779-5835

SOURCE: R1381 Sharp Carousel over the range microwave

I know this is late, but I have instructions for this unit. Remove the grease filters on the bottom. Inside the exposed hole there should be two gold colored bars. These are attached to plates at the top of the until which hook onto the mounting plate. Undo the screws at the bottoms of the bars and pull them down. This will unhook the unit from the top of the wall plate. Roll the unit forward and unhook from wall plate.

Maybe. The presence of metallic material (foil, stainless steel silverware, etc.) in an operating microwave oven creates electric arcs between the foil and the inside wall of the oven. And this can destroy the electric components.

This is not good, the magnetron is arcing because metal is exposed, this will eventually destroy the magnetron making the oven useless. I strongly suggest it get looked at for safety and potential fire hazard.

After running for around 5-10 seconds, a large "spark" can be seen arcing inside the microwave accompanied by a "shorting out" sound.


It is the magnetron that is arcing and potentially very dangerous, the magnetron is failing or there is exposed metal or to much food particle build up. I suggest unplugging the unit and have it checked out for safety reasons.

Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing
