Popular General Electric Microwave Switches
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.

light worked, timer and control pad worked, but no turntable, no heat, no noises of any sort, just didn't start up
Noted on partselect.com that someone else with this problem, found it to be secondary door switch. There are three door switches in this model, but online info noted that one of the three might feel "soft" (in my case, one switch clicked in a rather "jiggly" way, the other two were strong decisive clicks.) To access the door switches on

this model was the only difficult part. First use a torx bit to remove the two torx screws below the latches inside the microwave. This frees the latching part inside, that holds the door switches, which you will remove after you take off the control panel. The top grill has to come off before you can remove the door panel. Remove the screws above the grill, on the microwave top cover, The grill on this model is covered with a panel that moves out when it vents. After removing the two top screws, the covered grill vent slides left to remove. Be careful, as the sliding tabs are plastic. Wiggle and jiggle it, to slip it off. Below the removed grill, is a small metal grill with one screw in lower center. Remove that screw, and wiggle that out. You'll then see the one screw that holds on the control panel. Remove this screw, and lift the control panel up to remove. Again, go slowly and gently, as the bottom tabs holding the control panel in, are also plastic and easily broken. Lay the control panel on something, (I used the coffee maker) and pull out the wire bundles tucked on the left, that are attached to the latching panel. Wiggle the latching panel gently to lift it up off of it's plastic tabs and pull it out towards you, so you can see the three door switches. Each switch (part number WB24X829) has a little black switch on it. Feel each switch with either your finger, or a screwdriver to see which one doesn't "click" strongly. The weak one is the one you will replace. The door switches are fitted into a tab, and plugged into their wires. Remove the defective switch, pull out the wires, and replace it with the new switch, plugging back the wires, and slipping it back into it's plastic tabs. Then put everything back together in reverse order. The entire job took me fifteen minutes EXCEPT for figuring out how to slide off the upper grill, which I have told you. A repairman would have cost $150, the part was $18. AND, there's a good chance, the other two switches will get "used up" in the next year or so as well, so I'll be ready next time. Thank you, Partselect, why work all day, to make money, only to give it to somebody else, for fifteen minutes of work. All I needed was the knowledge.

Unplug your microwave before attempting this repair. You will need to remove the grill, which is held into place by two screws at the top of the grill (open your microwave door before doing this). Remove the grill. Remove the screw on the left holding the control panel in place. Loosen the screw behind the panel. You should now be able to lift the panel up and pull forward to detach. You will find the door switch by removing the screws to detach the switch assembly. Press on the release tab to remove the middle switch. Disconnect the wire connector to release the old switch. The door switch is normally closed.

GE Microwave turns on when door is opened
I saw a similar problem description at partselect.com and was confident to take the challenge to repair it myself. (Thanks to partselect.com). When I opened the microwave cover I found 3 similar switches. 2 of them works the same way and the other in reverse direction. Image diagram provided to buy parts is helpful to identify the switch.

This microwave door switch provides power to the various components in the microwave when the door is in a closed position, and interrupts power when the door is open. This door switch is approximately 1 1/2 inches long, and has 2 metal prongs called terminals that extend from its body. If your microwave will not turn or heat properly, there could be an issue with the door switch. You can check the switch for continuity using a multi-meter. With the actuator button depressed, you should see continuity between these terminals. If there is no continuity the switch will need to be replaced.

eft side of this difuser, but difuser is slotted for easy removal). Once the difuser is removed you will see 1 screw at the top that secures the pannel cover on the left side of the unit. Remove screw and slide this panel slightly up and out. This exposes the plastic frame that holds the upper and lower door switches. To locate the door switches and observe how they work, close and open the door and watch the door (bayonets) open and close the micro switches. Do the (red) buttons on top of the switches move up and down when the door bayonets push and release? If the buttons do not "pop" up when opened the switch is defective. The switch frame is secured with 2 screws. Remove screws and rotate the unit out for easy access to the micro switch(s). The internal (spring?) on my unit that is suposed to allow the red (visible) button on top of the switch to "pop" up when the door is opened was broken. Carefully pry the switch outward while being careful to lift the plastic holder-piece that holds the switch in place. Be careful, there is a small pin on the frame, so rotate the switch OUT toward you while lifting (carefully) the plastic holder-piece (you will see it on top of the switch). You can use an ohm meter to test the continuity of the switches. But if the buttons don't "pop" they are defective. Replace switch and reassemble.

Microwave not heating
Rmovd top vent screen. Removed control panel. Removed fuse cover panel. Replaced fuse. Removed housing of door switches. Removd wiring from door switches and and removed door switches from housing. Replaced with new switches and re-connectd wiring. Re-attached panels.
This switch monitor interlock is a critical safety component designed to ensure proper communication between the microwave door latch and the control board. When functioning correctly, it confirms that the door is securely closed before allowing the microwave to operate. A damaged or faulty switch may prevent the unit from starting, even if the door appears latched. Replacing this genuine part restores safe and reliable operation. Installation should be performed with care, and it's recommended to disconnect power before beginning any repair.

itch (which is the middle switch) and tested it for continuity. This is a normally closed switch. I tested the other two switches as well and found these (normally open) switches for continuity to be good and the monitor switch to have a short. This switch should show continuity when the door is open and should show no resistance when the door is closed. (Take care removing the switches) After I received the parts I installed them in the new Locker Holder and installed the latch board (ensure to follow the latch board adjustment steps located in the control board). I then attached the wiring to the control board and then plugged in the unit. I tested the unit to ensure it functioned correctly. I then installed the outer cabinet, and then installed the unit above the range (Use 2 people for this process). Overall an easy fix you just need to ensure you follow safety procedures (especially when dealing with capacitors.
Take a lot of pictures of the wiring and of the components and take care with the latch board or you'll have to buy a new one when all you really needed is a monitor switch.
