Question about Sharp Microwave Ovens

Sharp Combination Oven R-953M - Replaced door latch. Now everything works lights,display,turntable,fan,grill & oven. But microwave does not heat water in a cup. Could trouble be one of the three switches that the door latches bump against when closed? Thanks, Paul.

If the turntable runs when you try to cook with the microwave portion, then the problem is either a bad relay on the control board (RY2, primary interlock relay) or something wrong in the high voltage section.

If a high voltage problem, it may be as simple as a loose connection on the magnetron terminal or a bad high voltage rectifier diode or as costly as a high voltage transformer or magnetron.

Most of the time the magnetron will have a 5-9 year warranty, and you would only have to pay labor charges to have it fixed. If you take it to the shop yourself, you can save quite a bit.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Everything works. Time, fan, turntable, light. It


Magnetron and accompanying high voltage diode are usually to blame. Everything else works but the magnetron isn't resonating (providing the proper energy to excite your water molecules).
An appliance repairman can change it for you (typically $180) or you can get a new microwave.

Sharp carousel convection/grill/microwave maybe R990


Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck .

Sharp 930 AK Convection/Microwave Oven


When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.

Microwave not heating up


Check the door switch, when it is faulty the oven will turn on but turntable, fan and magnetron wont operate.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

Sharp 1870 just quit cooking and no turntable


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

Sharp R-953M combination oven. Display not working.


We repair those for $39.95 mostly for US and Canadian customers, but in the UK you can contact Quality Electronic Repairs. I think they repair these.

Otherwise, you would have to replace the control unit, which consists of both circuit boards and the display.
