Since it's not heating AND the turntable is not turning, it's almost certainly a bad door switch or possibly a bad door switch mount.

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

R-402JW-T won't cook


From your description you have a bad door switch, there are usually a few of them located inside the microwave under the keypad control board that will need a digital meter to trouble shoot.

Glass turntable in tricity tmc209 says "microwave only" What do I use for convection or combi cooking? Does turntable still need to rotate for convection cooking?


definately dont use the standard glass plate for convectional 'oven' cooking, as it will shatter. i have had TWO plates shatter so far before realising they should only be used for microwave cooking.

Sharp R-1871 microwave/convection oven. Microwave will not work


This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

Lights, fan,etc work but turntable does not rotate and oven does not cook.


Sounds like the table motor may have an issue. You might want to consult you local repair depot for an estimate. Sometimes the repairs are more than the appliance...beware!

Sharp Microwave Lights Up, But Won't Rotate or Cook


Hi. I would suggest checking out the door switches. There are usually 3. If one of those has failed then the microwave won't operate because of safety reasons. Best to replace all three. If the display on the unit is still fully operational I'd say go for the repair.

Clicking sound sporadically


That particular skillet is just too heavy a load for the turntable system to handle.

I would suggest a lighter skillet or a different container, otherwise, the motor or shaft or both will be damaged.

It is of course perfectly okay to put metal in a microwave (after all, that's what they're made of!) but you just have to do it only according to the instructions in the owner's manual.

And as you know, metal in convection mode poses no problem at all.

You just need to use a lighter or different container.

The turntable on my microwave/convection oven Model R930AW-P doesn't turn. The turntable motor shaft moves freely, but when the turntable is on it and cooking food, the turntable doesn't move.


You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. You may have to cut the cover off with snips, then use a screw when reassembling it.

We have the full service manual for this oven, and have uploaded it to our site here.

The best place to order Sharp parts is Tritronics.

SANYO EM-D9550. Turntable turns when off but not when cooking.


That's sounds pretty strange!

Since I don't have any service data on Sanyos, I'd have to speculate.

I would guess that one scenario that could cause it would be if the turntable were turned off via the control panel, but there was a switch or switch mount problem.

I would refer you to their support people:
