Secondary Door Switch
PartSelect Number PS237421
Manufacturer Part Number WB24X829
The secondary door switch is a simple on/off mechanism that stops the microwave from operating when the door is open (normally opened). The switch monitors the door latch position, and communicates whether the door is open or closed to the electrical control board. This door switch is approximately 1 inch long, and has 2 metal prongs called terminals that extend out of its body. Common symptoms related to a faulty secondary door switch include: microwave will not turn/shut off, or the microwave will not heat properly. NOTE: Before you begin this repair, first make sure your microwave is unplugged, and that your capacitor is discharged. A capacitor stores large amounts of electricity even when your microwave is unplugged.
