How to check if a microwave magnetron is working?
You can check to see if the magnetron is working by unplugging the unit, removing the cabinet housing, safely discharging the high-voltage capacitor, and removing the magnetron. With your multimeter, you can check the charge from the terminals. They should read 2 to 3 ohms of resistance if the magnetron is still working. Then, use one probe to touch the metal housing that encloses the magnetron; if it reads zero, there’s a problem. This step should only be completed once the capacitor has been discharged properly using a rubber-handled screwdriver or other safety tool.
Where is the diode on a microwave?
The diode is the piece of equipment that helps channel and provide the electricity in one direction to the magnetron, and it’s usually located behind the microwave front panel near the controls. If it’s burned out, then the microwave won’t generate power to spin the magnetron and heat the food.
