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
