I would most suspect a shorted high voltage rectifier diode, a bad connection on the FA terminal of the magnetron, or a bad magnetron.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

You can usually find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

My Sharp R-1870F microwave in our rv heats intermittantly and the turn table is stuck. Any advice?


Hello,

Check the oven door if it locks up, the oven has an automatic feature that when it is not closed properly it won't initialize. Since it heats up intermittently I think the heating capabalities of the microwave is still good, and this problem might be just due to something that is preventing it to operate. which most likely the the locks of the door.

Had problem with Sharp R-520L. Microwave suddenly


One of the door switches is the problem. Open the casing, and you should find the schematic diagram. Find the switches, and test if you can. If you cannot - replace all of them except the monitor switch.

My microwave does not heat anything. The touchpad, exahustfan, light works. The motor turns on and turn-table works for the number of mins specified but does not warm up the stuff. Please help!


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.

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.

Most likely the lower door interlock switch is bad. Cheap and pretty easy repair.

Martin Microwave Inc. sells the switches for around $5....
