Question about Sharp R-1874 Convection/Microwave Oven

3 Answers

Built-in Sharp Carousel II Microwave Convection Oven died.

I have a built-in Sharp Carousel II Microwave Convection Oven that I inherited when I bought the house. No manual. After working fine for almost 2 years after we bought the house, all of a sudden, it died. The clock also died. I checked my breakers - all appear OK. Other electric in that part of the kitchen is working fine. Any suggestions?

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!

    Had exactly the same problem, was the Fuse. It's replacable without removing from the wall. Unplug first! The fuse is connected directly to the line voltage, so if the microwave is plugged in, you will be killed. Remove center screw to take off the long plastic top vent, remove screw just above control panel. Control panel slides up and pops out, mine was sticky, but eventually popped free, don't pry. Make sure it's unpluged!!!!!! Look in, the fuse is a ceramic tube about 1/4" dia. and 1" long, to the left, about mid way up behind the control panel . My hand fit in, and I was able to remove and replace the fuse without disconecting anything internal. Be sure to use a 220V 15A fuse, not a 32V as was used in cars. Remember, you are touching bare parts connected to line voltage, if you get shocked, it's your own fault. Be sure to re-assemble before plugging back in, as microwave leaks are also dangerous.

My sharp carousel II microwave no longer heats food. Do I need to buy a new one?


The problem maybe the magnetron, or the inverter board if 7 years old or less, and possibly the keypad control board, by the time you add parts and labour cheaper to replace the microwave oven in the long run.

What is a replacement microwave for the Sharp Carousel II model R-9H81. I currently have this built-in oven and need to replace it with one of the same dimensions. Thanks.


You can contact Sharp at 1-800-BE-SHARP (1-800-237-4277) or visit them online.

They should be able to recommend a "drop-in" replacement.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Sharp carousel II microwave/convection oven


The question is... Do you want to put money on a 18year MW, or put it towards a new one? I must admit I love the SHARP Combo MW Convection ovens. I own two. One is almost 25years old. The mechanical Timer Type, but they work great and I can maintain them with 30years ef exrerience. I am now retired.
It does sound like the Magnetronhas broken down, however it could be other things in the Secondary (High Voltage Side). The High Voltage Side is made up of the Secondary HV side of the High Voltage Transformer, A High Voltage Diode, a High Voltage Capacitor, and the Magnetron. The High Voltage Side is DANGEROUS, and CAUTION should be taken to protect yourself against EXTREME HIGH VOLTAGE. unplug from power and DISCHARGE High Voltage Capaciton to frame GROUND before touching anything!!!!

Microwave convection oven repair needed


Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. I tlooks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.
