My-microwave-is-loud-and-not-heating-up-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 you'd like to support the channel, you can do so by shopping for tools or whatever you need on amazon through this link, https://amzn.to/2mfxmeq type in t..., 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 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., watch the microwave during use. if there is no light when the microwave is in operation but it heats food properly without noise or odors, the bulb is burned out and should be replaced.. My ge profile spacemaker 2.0 started to hum a bit louder and now makes no heat. i followed the ge troubleshooting flow-chart and it points to the magnetron, but the resistance checks (continuity pin-to-pin, open pins-to-case & no sign of any arcing or cracks in magnets)., the magnetron makes the heat, so disconnected it cannot. leave the wires off the mag. disconnect the other wire from the transformer that goes to the capacitor and run the unit again-if quiet then you have either a bad diode or capacitor here then so you would replace both of them..
Warning!! always put safety first when dealing with electricity!!! microwave not working?? quick troubleshoot and what you may need to fix video! to support ..., 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..
