Line Fuse


Every microwave oven has a line fuse. This fuse is designed to blow if too much current is drawn through the microwave circuitry. The fuse can be replaced, but the underlying issue should still be investigated and resolved. Otherwise the new fuse will blow also.
Main Control Board


If the microwave is not working the main control board may be defective. This is not common. When a microwave stops working the problem is usually the line fuse or within the high voltage circuit; either the high voltage capacitor, diode, transformer or magnetron.


Thermal Fuse


If the microwave is not working the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.
Thermoprotector


If the microwave is not working 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

microwave ovens

when that happen to me i change the bulb and the fuse in of the microwave f the don't work send it to the company that made it and they should tell what wrong.

turn table motor may be going bad.. it is almost impossible to diagnose untill it stops working completely.. when it stops working completely you can test for 120v down at the motor if you get 120v you need to replace the motor.
