How to Troubleshoot & Replace Ge AP2622452 / WB24X10047 Door Interlock Switch

Replaced upper latch micro switch. (After removing the Advantium from the wall and removing the cover, all four fuses, the diod, and Magnetron tested okay with a multimeter. The upper latch micro switch was visibly defective - the spring function no longer worked.) 

Replaced door switch for the second time in 8 years of ownership. New switch looks a little different so hopefully it's been upgraded. Unplug, take off upper vent cover (2) screws, open door, remove screw on top of display pannel. Lift pannel and let pannel hang out of your way without removing any wires. On left side remove upper screw that hold in door switches. Remove switch, disconnect leads, install lead on new switch and make sure connection is good. Reinstall new switch and reassemble pannel and vent cover. 

Watched a YouTube video for simple switch replacement. 

I told Appliance Parts what the problem was and a Tech e-mailed me what the problem was. It was a door switch. He also included how to check the switch with a volt meter. There are three door switches. I checked them and found the bad one and ordered it and fixed the problem. Both the Microwave and Convection oven work as new. 

Replaced door switch obtained from Appliance Parts. 

Replaced the door microswitches. I ordered the parts from Appliance Parts Pro's and received them the next day. All parts came in Genuine GE Parts packaging and they worked great. Other than having to figure out the sequence of removing parts to access the micro switches the replacement was really straight forward and fairly easy. 

Found a YouTube video that indicated a bad door switch. Did a continuity check on one of the switches and confirmed it was bad. Found the part easy on your site and got it the next day. Easy fix for only $32 including shipping. 

YouTube videos identified the likely problem and gave me confidence to open the GE microwave panel and test the switches. The major difficulty was removing the defective switch from the frame. The replacement switch arrived in two days and was quickly installed. Everything is working. 

Ordered part. 

After reading the helpful troubleshooting stories on your website, I disconnected the power from the microwave and had a look around behind the control panel and behind the door frame. I saw the microswitches mentioned in the troubleshooting information, and I immediately noticed the primary interlock switch was charred. I disconnected it and tested it for continuity. Indeed it had failed. I ordered the replacement switch and something told me to also order the latch board which holds the switch. I was afraid I would damage the existing latch board, I suppose. I'm glad I ordered both items. When I removed the old switch from the old latch board, the tabs which secure the switch broke off, as they seemed brittle. Once I discovered that the switches pivot on a plastic pin before locking in place, I quickly and easily installed the new switch in the new latch board, along with the existing switches, and the microwave came back to life when I restored the power. I was very pleased with how quickly I got the job done and that I thought to order the new latch board. I saved a lot of money by avoiding a service call, too!
