Customer Questions and Answers for Fuse, 20Amp by Ge

Hello Deena. It is located in the control panel section of the unit. You must remove the outer cover off the microwave to access and replace the fuse in the unit.

Hello Rita. 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 trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.

William, With the microwave working the fuses would not have anything to do with the cooktop lamps not working. The lamps route through the control board and if the control board is not sending power then the board would need to be replaced.

Steven, remove the top vent grille 1. Disconnect oven power. 2. Remove Phillips-head screws (2) from grille. 3. Lift bottom of grille and push top of grille down to remove. Remove the control panel 1. Disconnect power and remove grille. 2. Remove I screw at top of control panel. Lift up on control to release tabs. 3. Disconnect grounding screw and connectors. 4. Lift up on control to release hinge from mounting screw (GE Models, others remove mounting screw). The fuse WB2X3910 and fuse holder WB06X10005 are located up near the ceiling of the opening, and can be removed and replaced.

Hello Martin, If the fuse is blown, you need to check the following to prevent a repeat of the same issue. Check the interlock switches for the door, the monitor switch, the power relay (ry-2), the varistor, the power transformer, and the high voltage transformer. There should be a mini manual inside the unit with the specifications on the parts. If not or you should need any further assistance, please let us know.

Hello Ben. On most GE model microwaves, when this is on the control, it indicates the keypad is bad and will need to be replaced. However, to be sure, we would need the model number of the unit. Please post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx

Chris, Based on the post information, at this point there are a couple of possibility(s) a faulty monitor door switch [AP2024338 or wiring or the control board secondary relay WB27X10032 not completing the circuit. Thanks and Good Luck

Hello Linwood. Yes, based on the model, WB2X3910 is the correct fuse. Hope this helps.

Pat, No, it's not likely to be the fuse. It's most likely a faulty touchpad assembly WB27X10357 . The circuitry in the touchpanel has started to deteriorate and has become inoperative for those two selections. Good Luck and Thanks

Hello Steve. No, this part can be installed either way. I hope this info helps.
