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.

Found the answer by calling a Sharp technician and they said it was the magnetron tube, which is not worth fixing :( Thought I'd pass this on to anyone that has yet to find out.

SOURCE: Turntable does not rotate

Hi there,

Well it seems that there is some fault in the turnable motor, turntable system consists of the motor and coupler, turntable support with rollers and the tray.
I have a video link to help you more on this -- how a turntable motor should sound when you rotate it by hand... please follow the below link -

http://www.youtube.com/watch?v=rPSWi_z7M58

If motor grinding... etc., it means you may have a bad motor or plastic coupler.

Post further comments if you need more help....

Good Luck!!

SOURCE: sharp carousel II microwave/convection oven

Hello, I just purchased a Sharp Carousell II convection microwave oven, also built in 1990, serial number 212806. I think the model number is R18244, but part of it is worn off. Can anyone tell me how to get a manual for it? I have never cooked with a convection oven before.
Thanks

MODEL R-395Y sharp carousel microwave not working. All power outlets are fine. Please help, cheers lyn


I was unable to locate a service repair manual specific to your microwave; sorry.

You'll must likely have to find a Sharp service and repair center.
I've attached a link that contains the user's manual to your microwave...it has the phone number and address of Sharp; perhaps you can phone them and ask where a repair center is located.

This is the diagnostic check list Sharp recommends before calling for service:
SERVICE CALL CHECK
Please check the following before calling for service:
1. Does the display light up?
2. When the door is opened, does the oven lamp come on?
3. Place one cup of water (approx. 250 ml) in a glass measure in the oven and close the door securely. Oven
lamp should go off if door is closed properly. Press the INSTANT COOK/START pad once.
A. Does the oven lamp come on?
B. Does the cooling fan work?
(Put your hand over the rear ventilation openings.)
C. Does the turntable rotate?
(The turntable can rotate clockwise or counterclockwise. This is quite normal.)
D. After one minute, did an audible signal sound and COOK
indicator go off?
E. Is the water inside the oven hot?
If "NO" is the answer to any of the above questions, please check your wall socket and the fuse in your meter box.
If both the wall socket and the fuse are functioning properly, CONTACT YOUR NEAREST SERVICE CENTRE

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work


Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

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.

You have to replace that small screen which is called wave guide. If there is a sharp authorised service centre near to your place you can buy the part from them. Do not work the oven without replacing that part.
