Question about Sharp R-303CW Convection / Microwave Oven

1 Answer

It just doesn't work.

My husband plugged in the microwave in one spot (and it worked), then unplugged it to move it somewhere else. When he plugged it in again, the microwave never turned on. No lights on the display, no sound, no light inside, nothing. He didn't hear a noise or smell a burning smell or anything like that. Do I have to get a new microwave?

    My microwave oven just turned off and is not able to power up at all. I checked the connections and power source and all is good. Is there a reset button on this unit or what else should I try to do

Did he plug it back into the first spot? Assuming so and assuming it still doesn't work, then I would say that you have a blown fuse. That can be caused by a loose fuse holder, misalignment or damage to the door, etc. It may also have an open or tripped thermostat. We have text files covering critical safety, disassembly, and door switches. You can find them via a search on Yahoo.com (not Google) for this: microwave circuit repair At this point the oven needs to be checked out a bit. With these text files, and proper caution, it can be done pretty easily.

Could be the outlet that it is plugged in,turn the circuit breaker off,wait a few minutes,then try again ,or it is pulling to much power from the outlet,something else might be pulling from it,maybe try plugging it in somewhere else.

Sharp Carousel Model R-209KK-W is flashing all 8's and keypad not working

The first thing to try is to do 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 about 5 minutes.

If it still doesn't work, it may need repair, which can be done for $39.95 in most cases.

Microwave not working

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.

Otherwise, your controller or keypad may have moisture on it.

Maytag Over the Range Microwave

Assuming the entire power line from the breaker to the microwave cord is okay, it's almost certainly a bad connection on the circuit board of the control panel assembly. For reference, we repair these from all over the country for $32.50 postpaid.
