I have a GE microwave from 2012 (WES1452SS1SS) That developed door switch issues. It would stop mid-cook or not start at all. I used it for years this way until it had a full failure. I opened it up and found the lowest door switch had failed. That switch is for the door open lever on the front. I ordered 3 new Omron switches of the same specs from Newark. They went in fine, and I had reference pics to compare wiring. Now the light and fan com on with the door closed instead of open. I tried running it for a few seconds with the door closed and it blew the fuse? I don’t have my multimeter here to check things. What could the problem be? They’re simple switches and fit perfectly. The old switches were Starion SZM-V16 and the Omrons are V-15-2C26-K
Hi Ryan, Those microswitches come in three flavors, NO (Normally Open), NC (Normally Closed), and ones with three contacts that support both. I’m seriously wondering if you’ve gotten one that’s backwards from what you wanted; i.e., NO when you needed NC or vice versa. Whenever I’m replacing door switches, I just buy the one that supports both operations; that way I can use it in any position whether it needs to be NO, NC or both. Here’s a picture of a switch that I’m talking about.
The red arrow is pointing to the common connector; that one is used on all switches.Orange shows the NO contact and yellow is the NC contact. Check your replacement switch against the original and verify that the contact you have is in the same position on both switches. If not, there’s your problem; you’ve got the wrong polarity switch.
