Sharp R-1502 Hello, I have a Sharp R-1502 that won't heat anything. The display operates correctly, the function buttons operate, and the turntable rotates.

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

Sounds like the power relay has quit. Time for a new one.

This is probably a shorted high voltage rectifier diode. See this link:

(if it's not shorted or burned, it's probably okay)

Found spare parts supplier on web thank you. Hopefully it will be the correct turntable motor - otherwise, I will just have to buy a new Microwave.

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.

The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

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. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

We have the service manuals for this model and have uploaded them to our site here and here to help you.

You will need the free Acrobat Reader to view or print it in case you don't have it.

The best place to order Sharp parts is Tritronics. You can also call them at 866-779-5835.

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Microwave Oven Basic Troubleshooting Tips

The fact that all other functions seem to operate ok, indicates that you might have a problem with the motor that turns the turntable.

If you try to turn the turntable manually (gently), does it turn freely or is there resistance? If it turns freely, the mechanical mechanism between the turntable and motor may be broken and the motor may be ok.

The oven's microprocessor also controlls the motor. There could be a problem there.

You'll need to have it looked at by a service center. Although its not that difficult to determine which of the reasons I mentioned above is the cause, it can be however, dangerous to operate a microwave oven with the cover off and with high voltage circuits exposed.

Please let me know if I can be of further assistance to you.

Good luck!

Waleed, Since the microwave is going through all its motions we can feel safe that the oven and magnetron thermostats are ok. If they were bad you would not have a display. Just inside the control panel to the left, you have 3 switches which the door activates. A primary (top switch) a secondary (bottom switch) and a monitor switch (middle). If the primary or secondary switch is not closing when the door is shut, you high voltage side will not activate, therefore no heat. If the monitor switch failed or found either the primary or secondary switch closed with the door open, it would blow the main fuse and the oven would be dead. Therefore Im leaning on either the primary or secondary switch not operating correctly. When checking these switches, unplug and discharge the capacitor. This is high voltage. Good luck
