Typically in a microwave, you get into programming mode (sounds like the auto/clock button is doing that) set the time and then press START. Give that a try.

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: 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 clock works & counts down but the microwave won't heat


  • Disconnect the power for 30 seconds. After restoring power, do not set the clock.
  • If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.





Touch the clock pad. Enter in the correct time of day by touching the numbers in sequence. Touch the clock pad again.

The door on my Sharp Carousel II Microwave Oven will not open. The display says LOCK. Looking at my booklet revealed that there is a safety lock feature. I tried to cancel by touching Autostart/clock,...


Sounds like a drawer type microwave or a combo oven and microwave?

If your manual's instructions didn't fix it, you can try a hard reset.

Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

If you still need help, please reply back with your model number so we can help you.

Sharp Carousel Microwave R-320FQ Serial # 26805 Mfg. Dec. 2002


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.

Let us know if the hard reset does not fix it.

It may have an intermittently shorting keypad or another problem on the control panel, which we repair for customers nationwide with our guaranteed $39.95 service.
