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.

What is the name of the lowest switch on the latch body? I see the secondary switch and the monitor door switch in the diagram, but i don't see the name of the lowest switch.
For model number JVM1750SM1SS
Hi Tom,
That is a great question! The bottom switch on the latch body is another Secondary Switch part number PS237421. The top and bottom are the same switch and the middle is the Monitor.
Good luck with this repair!

My microwave turns on when i open the door. What causes this?
For model number JVM1730DP1WW
Hi Kelly,
Thank you for your inquiry. Based on what you described, there are 3 switches in your microwave that you will need to check to see which one is causing the issue. You will need a multimeter to verify which one is the faulty switch. I hope this helps. Thank you and have a great day!

I read somewhere that you should make sure the capacitor is discharged before you work on a microwave. How do you find the capacitor and how do you discharge it?
For model number jvm1950sr1ss
Hi Jack,
Thank you for your inquiry. The capacitor is found in the back of your microwave. The capacitor is discharged by creating a short circuit between the two capacitor terminals and from each terminal to chassis ground.For the proper procedure to discharge the capacitor, you will need to consult your owners manual. I hope this helps. Thank you and have a great day!

I have 3 dor switches on my micro. Looking at diagram, only 2 switches are called out with numbers, door switch #29 (upper) & #30 (middle) in the diagram, they show as two different switches upper wb24x829 and middle wb24x30. No number for the lowest switch. However when i look at the switches on my particular unit, the upper and middle switch are the same and the lower 3rd switch is a different number. What should i order to replace all 3 switches? Which goes where? Follow what is on my unit or per the diagram? The switche have never been replaced. Thanks in advance for the help.

Hello, microwave fan, light and turntable do not come on when door is closed. Key pad works fine. When i try to start nothing happens but then if i hit start again i hear an electrical noise, again with no fan, light and turntable. Already replaced the line fuse and i have the same problem
For model number JVM1650SH01
Hi Matt,
Thank you for your question. If the microwave is not working when the door is closed, there are some parts that you will need to check to see which one is causing the issue. You will need to check the fuse, the secondary door switch, the monitor door switch, the light socket, the drive motor, the thermostat cut-off and the thermal cut-out fuse. I hope this helps. Thank you and have a great day!

Can I get to the interior light to replace it or do I need a technician to come out and do it? I'd much rather do it myself...but I saw on another site a call needed to be scheduled.Thanks!!
For model number JEM25DM3BB
Hi Christy, Thank you fort he question. You can do the repair on your own but you will need to be very careful and discharge the Capacitor. It can hold a charge long after the microwave has been disconnected from its power source.You will need to touch the blade of a insulated handle screwdriver to one of the capacitor terminals and hold it there for a few seconds. Repeat this process a few times. Hope this helps!

My microwave fan motor run every time no stop door seitch ok some panel button no work
Hello Reinaldo, Thank you for the question. With the information provided, sounds like a stuck keypad, Part Number: PS2374119. The fan button could be stuck on and not allowing it to turn off. This would also explain some buttons working and others not. Hope this helps, good luck with this repair!
Microwave buzzes when close door. Stops buzzing if left open. Which switch do I need to replace?
For model number JEM31SF001
Hello Dave, Thank you for the question. I suggest testing each switch to see what switch needs to be replaced. The PartSelect Number PS237421 should read Normally Open and the Part Number: PS237422 should read normally closed. Thank you for your inquiry, good luck with this repair!
Microwave stops working and has this electrical hum when the door is closed. It did this once before and we unplugged it over night and then it worked again. Now when we unplug it and plug it back in it still has this electrical hum. Its about 9 years old, is it on its last leg or is there a reasonable fix?
For model number PVM1870SM1SS
Hello Joe, Thank you for the question. I suggest testing the Door Switches Part Number: PS237421 and Part Number: PS237422 for continuity. This is a common issue with a switch issue. Hope this helps, good luck with this repair!
Microwave was working fine until one day about 1 min into heating the normal hum and table stopped. Turning off power for 10 min would fix it. Now turning off power doesn’t help. Keypad works fine, microwave light turns on with door open, exhaust still works. It will even count down but no heat. What should i check?
For model number PVM1870SM1SS
Hello Jason, thank you for your question. I would recommend checking the line fuse, the diode and door switches first. If those all test as being working parts, you might need the magnetron. I hope this helps!

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)
After closing door the display panel must be tapped on to keep the unit operating.
The switches are not the problem! The problem is in the tolerences of the latch housing. I have ordered two new housings (Upper & Lower) and will see if the tolerences are closer. If not I will try epoxying a shim to the plate that operates the microswitches. The other option is to file the mounting slots of the housing to allow adjustment, which would be iffy,keeping them from moving with use. The exploded drawings really need to be clarified. The scale is way too small. It was extremely difficult to pick out the individual parts of the mechanisiam.
All electrical worked (fan, lights, control panel) door switch was broke. Pulled the oven out. Took out two big screws from the cabinet above. (be careful not to drop oven)Set the oven on kitchen counter. Took off five screws that held the vent cover. Removed vent cover. Took out one screw that held the control panel. Lifted, turned and slid the panel into the space below so I could get to the upper door switch. Replace door switch and re-assemble.

Microwave stays on when door opened
Removed control panel first then removed bracket holding door switches 8 screws total very easy fix ????
After researching on line and watching installation videos, ordered all three switches and installed. Disassembly of microwave was simple, removing the bracket holding the switches was a little tricky, it sits behind a metal post and you have to angle and wiggle it out. One note of caution when replacing all three switches, be sure to install correct switch in correct location. Had two of one style switch and one of a second style, and put one in wrong place, causing microwave to power up again when door was opened. After thinking it through and doing a second disassembly, and double checking installation instructions, corrected problem and microwave now works fine.
When you open the door at the start the fan wood come on
I removed the unit from the wall removed the top two screws holding the panel above the door I the two screws holding the control panel removed the three switchs I found the top one to be blown and replaced it

Microwave wouldn’t shut off when door was opened
Followed the online videos to enter the cavity to the switch holder. Noticed right away the dreaded capacitor was in back right corner behind where the touch pad had been removed. I isolated the capacitor with an old computer mouse pad for extra safety. Took some manipulations to get the switch mount out from behind the wire bundles. Once out front, easy to use small flat blade screwdriver to release each switch and replace with matching new switch. Only one switch was bad but replaced all three. Back together and working great.
Pulled it from the wall remove the front vent covers removed the control panel remove the door switches by a special screw driver bit which looks a star remove the electrical terminals pressed the plastic clip pulled the switch replaced it with new one then followed initial steps backward

Very easy to carefully take unit apart as others and replace. I was not for sure if this was the problem but I guess it was! Works like new again. Saved taking microwave down and replacing. Easy fix!

GE Microwave door switches
I am highly practiced at disassembly of my GE Microwave. When it malfunctioned after running and closing the door I surmised it was one of the 3 door switches. I ordered all 3 switches. The existing switches checked with a meter. I still replaced all 3 switches. That fixed the issue!
