Fan stays on when door is open, door switches test good

We recently started having an issue with our 6 year old GE microwave (model # JNM1951SR1SS) where the fan stays on when the door is opened. It's an intermittent problem, but in the last day or so the fan stays on almost every time the door is opened (turntable doesn't turn).

Sorry, I checked the switches again. You're right, the top and bottom are NO, and the middle switch is NC. I was going off of memory when I wrote my original post, so I appreciate you bearing with me. I retested all the switches again, and they all "appeared" to be changing state when I closed the door, according to my multimeter.

Hi Adam - I had the same issue and my Microwave is GE Profile. The Overhead Fan was TURNING ON, when I closed the door. I kept it ON for an hour and NEVER TURNED OFF. After my investigation and following your directions, the TOP Door Micro Switch (NO) was FAULTY (seems got HOT, Melted a BIT, and Went Bad) and verified/confirmed with Multi Meter too. I replaced the BAD Switch with a NEW ONE. PROBLEM FIXED and WORKS NORMAL.
