Customer Questions and Answers for High Voltage Capacitor by Whirlpool

Hello Desmon, There are several things that you would want to check. You would want to check the diode and magnetron thermal fuse to make sure that they have continuity. You would want to check the magnetron for ohm reading and make sure that magnet is not cracked. You would want to check the capacitor and the transformer. If these check ok then you would want to check the stirrer.

Hi Tony. Remove the unit cover assy. There is a 15a fuse in line from the power cord at the top rt. area of the controls. This is the first part I would check. Use an ohm meter on the fuse with it out of the holder. Part # W10856869. Thank you.
