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!!!!!!!

We see (and repair) this a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a week or so.
This light failure often occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.
Details of our service are at
our Web site, along with a video showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Feel free to contact me directly with your brand, full model number and symptoms.
