If my microwave works besides actually heating, would that be the diode or the megnetron? Should I order a diode and see if that is the solution as it’s much cheaper then the megnetron?
For model number WMH2175XVB4
Hi Mike, thank you for the question. According to our research, first, you may need to check the diode, part number PS12584264. When the diode burns out, the magnetron does not receive enough voltage to operate, preventing the microwave from heating up. When the diode fails, it is often visibly burned out. Inspect the diode, and if the diode is burned out, you may need to replace it. If the diode is not faulty, then you may need to check the door switch, part number PS10057151. To determine if the door switch is defective, use a multimeter to test the switch for continuity. If there is no issue with the door switch, you may need to check the high-voltage capacitor, part number PS11731152. If the capacitor is burned out, the entire high-voltage circuit will stop working properly, and the microwave will not heat. To determine if the high voltage capacitor is defective, use a VOM meter with capacitance testing capability. If the problem persists, then you may need to check the magnetron, part number PS11703077. If the magnetron is burned out, you may need to replace it. We hope this helps!
The nightmare was that this microwave is installed under the cabinet....in order to get to the light bulb I had to pull out my stove then squeeze into the space between the stove and counter....my old microwave light bult was much easier to change.....Shame on Whirlpool for making this so difficult.....must be a better way to cover the light bulb so that we do not need a screwdriver to remove the door to get to the light bulb
Ordered top & bottom micro-switches and mounting plate parts. Internet reviews could not find specifics if the issue was due to a top/bottom or combination of micro-switch or mounting plate failure. Pulled the plug. Removed the top vent assembly cover held in by 2 Phillips screws inside the vent. Removed the control panel held in by 1 Phillip screw at the top vent assembly area. Lifted control panel upward to release the catch and moved it off to the side - didn't disconnect any leads. Used a Torx bit to remove the door switch mounting plates at the front and pulled the plates through the opening from the control panel. Documented the wire color code connections, the top plate uses 2 micro's with one using both the closed & open contact. Installed the respective micros on the mounting plates and worked backwards with the wiring and removal steps. Once completed, the open/close sensing has worked every time.
