It has stopped heating. Should I repair or


Sorry to say, but you may have gotten your $'s worth, plus more! At this point any diagonsis and repairs would certainly not be worth spending $300-400 for another Sharp oven. Most likely, the magnatron has stopped working, which would explain why everything else is still operating.

Sharp modelR1381 everything works but will notheat


If it runs and makes normal noise but just no heat, issues is either a loose connector to magnetron or at diode to capacitor. Be careful with capacitor because it stores thousands of volts.

Everything seems to be working but it doesn't heat anything


Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

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

Not heating up anything


Not knowing how much run time you have on the microwave , makes it hard to diagnose the problem but If everything appears to be working properly (as you describe) then you may have a bad/damaged or disconnected magnetron tube inside it. That kind of service should be done by professionals. Exposure to Microwave energy is not something you should mess around with unless you know what you are doing.. Good Luck

Need inner door surround for a sharp 1000w R-21ATP Microwave


Start at the link below. Eventualy you will be led to a reliable source to purchase parts.

After the surround is replaced, it is important that the microwave oven is properly tested for radiation leaks. This is a serious specification. I think they will strongly tell you to send the oven in for proper service and testing rather than fix it yourself.
