My-microwave-not-heating-but-runs, 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.... 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., 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..
A new and better video update for the previous one where i explain how to fix your microwave that works but doesn't heat. easiest fix you can find. follow th..., 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.. When your microwave doesn't heat or start, it's probably in demo mode. however, there are some other things that can cause the problem such as door errors, an issue with the control panel, the setting being used, or not enough clearance., start right here find appliance parts, lawn & garden equipment parts, heating & cooling parts and more from the top brands in the industry here. click on shop parts, or select the kind of product you're working with on the left and we'll help you find the right part. shop parts.
My first thought would be a blown magnetron. on microwaves, these can generally go dead, usually with a popping sound. i think there might also be a fuse in your microwave, but i do believe that if it was a blown fuse, your mw would not start up. the technician should also not forget the door... - microwave, cause 1 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. if the diode burns out, the magnetron won’t receive enough voltage to operate, preventing the microwave from... - kenmore microwave
