Microwave-oven-working-but-not-heating, 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.... 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., 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..
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..., 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..
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., detecting the malfunction and troubleshooting. check the power supply voltage. when the voltage drops below 215 volts – the microwave does not heat the food well enough.. 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., did the keypad respond and the microwave start? yes no; did the water heat after the test? yes no; if the keypad does not respond, it is possible that the child lock feature is active.. child lock is a safety feature used to lock the control panel when cleaning the microwave, so that children cannot use the microwave unsupervised.
