Door switch inconsistent operation for Open/Close sensing.
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. Read more...

Secondary Door Switch
★★★★★
★★★★★
(39)
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.

Marla from Arlington, TX
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. Read more...

Micro Switch

PartSelect Number PS3522738
Manufacturer Part Number 3B73362F
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. 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.

Installation Instructions
JAMES from BILLINGS, MT
Broken door micro switch. (unit does not start heating)
Unplug the unit before servicing. Need phillips screwdriver. Open door. Use step ladder to access and remove 2 small screws from top of the room air diffuser at top of unit. Slide diffuser slightly to the left to align the diffuser's plastic tab on the left side to rotate toward you. (The wires for the front control panel are at the far left 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. Read more...

PartSelect Number PS237422
Manufacturer Part Number WB24X830
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.
Steps:
Remove the built-in microwave from the wall and keep it in an open space.
Remove the microwave screws and take the cover out.
Remove the 2 screws(inside) from the plastic panel where switches are snapped in
Gently remove the faulty switch and replace with the new one.
(In my case the topmost secondary door switch was broken)

ARNEL from WAUKEGAN, IL
Pressing the start, microwave will start and dies out. Electric is tripping.
The diagnosis is about an hour. Coz, I need to open the control panel, got a tester, and trsted all critical parts inside the panel.
Also, replaced the fuse just to make sure its a new one. Found out it was a switch (bottom part) that control the open/close of the microwave door.

When found out the problem, the rest of the work is easy.
