Oster-microwave-not-heating-food, 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 the high voltage diode or rectifier. this component helps provide the high voltage that powers the magnetron. the high voltage diode is located near the magnetron and the high voltage capacitor, so access will require removal of the cabinet., hello,usual problem with microwaves not heating would be busted diode form the high voltage capacitor to the chassis. in some models, there is also a fuse from the transformergoing to the high voltage capacitor. these two parts are the cheapest that you can replace..
Get tips to help you get back to successfully heating meals in the microwave again. there are issues you can correct yourself. transcript if you love to kick..., 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. how to test microwave magnetron with a multimeter:.
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, 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..
