Est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

How can I get the fan to turn off when the microwave is turned off?


Most GE over the range microwave ovens have a cavity heat thermostat. if the exhaust fan cut on due to external heat generated to oven, the fan will run until unit totally cools down. in this case unplug unit. Also fan can run if you have a broken door paw or if one of the door secondary switches is bad.

Fan failure /Intermittent heating


quite likely your microwave is trying to prevent it self from self destruct, because if the fan is not keeping the electronics components cool enough while its running the high limit thermo will disconnect power from the heating circuit, if the fan is not working it should be replaced , that's a techs job.

First the motor cooling fan quit working and then it was running without the cooling fan working and everything shut off. It is as if it is unplugged.


The cooling fan protects the magnetron from overheating when it is running, the magnetron has probably been damaged and has shorted due to the excessive heat that they generate and blown the main fuse in the microwave to stop any further damage. The repairs for parts and labor will not be justified and replacement in the long run will be cheaper.

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
