Probably Magnetron is burned out. Only way to know is servicing it.

I'd check to make sure you don't have a door switch that isn't functioning properly. Also, might be a control panel or control panel interface issue.

Runs but doesn't heat


if it has a turntable does it move? Possible diode, inverter board (may have the diode on it or the Magnetron.

If an inexpensive unit it may be cheaper to replace than repair.

Sharp micro doesn't heat


see this causes and fix it. God bless you
Diode The high voltage diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron which emits the energy that cooks the food. If the diode burns out, a lower A/C voltage reaches the magnetron, which is not sufficient to power the magnetron. When the diode fails it is often visibly burned out. If it appears to be good, it can be tested with a volt-Ohm meter capable of testing diodes. High voltage diodes frequently fail and are one of the most common points of failure in a microwave oven.

Door Switch If the microwave does not heat, one of the door switches might be defective. Microwave ovens normally have three door switches, if any of them fail the microwave does not turn on and does not heat. Check the switches for continuity with an Ohm meter.

Magnetron If the microwave oven doesn't heat the magnetron tube might have burned out. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. If the microwave oven is turned on when it is empty this can cause the magnetron to burn out. Once it is burned out it has to be replaced, it's not repairable.
High Voltage Capacitor If the microwave doesn't heat the high voltage capacitor might be defective. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor is burned out the entire high voltage circuit stops working properly. The high voltage capacitor can be checked with a special VOM meter which has a capacitance testing capability. Be aware that the high voltage capacitor can retain a charge of more than 3,000 volts and can injure or kill a person if not handled properly. Only trained technicians should perform this type of testing.

High Voltage Transformer If the microwave does not heat, the high voltage transformer might be burned out. Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food.

Thermal Fuse If the microwave doesn't heat the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Thermoprotector If the microwave doesn't heat the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.

Main Control Board If the microwave doesn't heat the main control board may be defective. This is not common. When a microwave doesn't heat the problem is usually within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.

what problem do you have mention ? attached is there a list please indicate. God bless you
    No Lights or Power, Unit seems Dead The voltage to the unit is good.Lights come on, but can not program unit, Touchpad dead
    Microwave Runs, but no Heat Turntable rotates, acts like it is heating but doesn't. This is the big one, many possibilities.
    Microwave Runs, Heats, but turntable does not move
    Microwave is arcing
    Microwave Vent Hood is not working Over The Range(OTR) Models.
    Microwave Stove Light not Working OTR models, light bulbs good.
    Microwave overheats and keeps turning off

Microwave wont heat up food


If your microwave runs, but doesn'theat your food, verify that you have selected a cooking setting. You mayaccidentally set the timer. Test the magnetron by placing 1 cup of water in themicrowave and heating the water for three minutes. If the water doesn't heat,your magnetron is dead.

Sometimes when I go to heat something in the microwave it doesn't heat but when I open the door and then close it it sometimes will work?


Sounds like the door switch is going bad this is the switch that "tells" the microwave the door is closed so that way it doesn't run with it open

The microwave timer runs but turnable plate doesn,t rotate and the heating elements doesn't comes on


you need a new microwave. There are no heating elements in mocrowaves just micro-waces. It only heats moisture it does not heat objects. It is to dangerous to replace the actual device that heats liquids.
