Microwave-running-not-heating, disconnect the microwave from its power source. remove the microwave’s cabinet to locate the magnetron. clean up the microwave cavity if needed; discharge the high voltage capacitor to ensure that the high voltage diode is working and the mounting bolts are tightened.. If your microwave oven doesn’t heat, you may have a problem with a door switch. the door switches, often referred to as interlock switches, provide power to the various components in the microwave when the door is in a closed position, and interrupt power when the door is open., a microwave that does not heat up may have a broken magnetron. this is the part that makes the heat to cook the food. if it is broken, it may blow a fuse in your microwave which could lead to other components failing..
New well explained video here https://youtu.be/sgj0hvi6aj4 if your microwave works, has power and timer runs but there is no heating, the most common problem..., microwave runs but does not heat if the microwave runs but is not heating, it could be one of many components. make sure the “timer” function was not inadvertently used. check to ensure the door is closed firmly..
Common solutions for: microwave not heating 01 - diode the 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 to heat the food., the two major systems in the microwave two separate but connected systems comprise the microwave's inner workings: the control section and the high-voltage section. the control section channels electricity safely from the source to the microwave i.... My ge profile microwave is running but not heating -- in doing research, it stated 80% of the time it is the fuse. - answered by a verified appliance technician, my microwave stopped working. the light would come on and the timer would count down but the heat didn't work and the turn table did not turn. see the easy, ....
Microwaves are truly dangerous. you do not want to fry yourself. strictly from an academic point, it could be the power diodes or a defective capacitor. your microwave may turn on but does not heat.
