Fine Your Idea

Microwave-is-not-heating-but-the-timer-is-working, 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. 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, ..., new well explained video here if your microwave works, has power and timer runs but there is no heating, the most common problem....

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., 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..

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., 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.. How to detect the malfunction. at first, you need to check a high-voltage fuse, check the parts diagram. if the fuse has burnt, we need to check multiplier components (here, the doubler components) – a diode and a capacitor., 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..

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.
