Why-my-microwave-is-not-heating-up, most times, when microwave ovens refuse to heat up as it should, its likely that the microwave oven magnetron has become defective. this main part of the microwave oven that is the responsible for generating the microwaves themselves.. The magnetron has burnt out. the magnetron is a critical feature of the microwave heating function. unfortunately, if the magnetron has burnt out, it can mean an expensive repair. if the magnetron is not drawing energy, it also means the high voltage capacitor could remain charged for a long time, which makes the microwave especially dangerous., when your microwave turns on but does not heat up, it may mean the door switch is broken. the door switch signals other microwave components to supply power when closed, and to stop heating when open. the door switch can also be called an interlock switch..
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., like any appliance in your home, a microwave can break down and need repairs. of course, this often happens at the moment you need it the most. whether your microwave is leaving too many unpopped popcorn kernels in the bag, or your frozen meals keep coming out chilly, the appliance experts at....
Fixing the magnetron. the magnetron is the part of the machine that generates the microwaves, which are used for cooking your food. if your magnetron is broken, that may cause your microwave to blow a fuse, in which case the entire machine won’t work., if your microwave is not heating, then the problem could also be with the magnetron. magnetron is an important part of the microwave and is responsible for providing the heat which cooks the food. in case the magnetron is broken then this may lead to blowing up of the fuse which could further result in 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..., 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. if the diode burns out, the magnetron won’t receive enough voltage to operate, preventing the microwave from heating. when the diode fails, it is often visibly burned out.
