Customer Questions and Answers for Capacitor High Voltage by Ge

Chris, if the model number of your appliance could be verified from the model/serial tag and provided in a new question, this may allow the most accurate information to be presented.

Lola, This issue will likely be that it would be either a capacitor that is faulty or a faulty transformer.

Carlos, The first check should be the door switches and bracket The WB24X25397 monitor switch, WB24X10047 primary switch have to have the proper circuitry, when the door is closed, or the fuse WB27X10928 will "blow". Then visually inspect the control board for discolored and damaged areas on the board, especially in the area of the RY2 relay on the board.

Hello Tony. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the transformer should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. All of these are +- 10%. If all the readings are proper and in range, replace the magnetron.

Hello Joe. You will need to order WB27X11033 for the capacitor.

Hello Gary. Sorry, we do not offer parts for that brand.

Ann, You will need to get the high voltage transformer WB27X10073.

Hello Jordan. Based on the information you provided, TJ13QBP21097K is the correct capacitor. Hope this helps.

Hello Jordan. The capacitor WB27X11033 is 2100 V and 1.05 F. Hope this helps.
