Microwave-not-heating-diode-and-capacitor-test-fine, 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.. Once you own a microwave oven, you can never go back to the days of waiting for food to thaw or stovetop reheating. if you have a convection microwave oven, then you probably do a good amount of your cooking with it., if your microwave oven doesn’t heat, you may have a problem with a door switch. the door switches, often referred to as interlock switches, provide power to the various components in the microwave when the door is in a closed position, and interrupt power when the door is open..
Many viewers have been asking how to test the microwave oven's hv diode. since ohm meters and diode checkers cannot test these diodes, i will show you a quic..., sometimes microwaves don’t break down completely as a result of a blown fuse or a busted transformer. instead, sometimes your microwave can carry on the passive functions of lighting up, telling time, and even rotating the turntable inside without actually heating up your food. in these circumstances, something is interfering with your microwaves ability to fully utilize its power. if ....
3. problem with the magnetron. 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 this video, i show you how to diagnose and replace a faulty microwave capacitor. if you are wondering why the microwave fuse board blew up, it is because .... When i start a heat cycle only the light in the oven comes on, no fan, no magnetron, turn table not moving, but the time counts down. i have tested several components and know some are good/working after replacing magnetron, diode, and hv transformer. i provided external power to the high..., the line marked as diode on (not in scale ) in the above drawing corresponds to the voltage developed in the hv diode in the forward polarization, a very very small voltage, as compared to the 5.6 kv magnitude, is applied to the magnetron..
** remember! ** the microwave can still shock you even unplugged!! always discharge the high-voltage capacitor first if you even think your hands will come close to any high voltage components. jeff mentions this: anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
