I heated up my coffee this morning and when it was finished I opened it as usual to enjoy my steamy cup and when I closed the microwave door it turned on again- lit and turning. I hit cancel but it kept going. I opened it, and it stopped. I closed it and it started on again. after several attempts of unplugging, canceling, open and shutting and banging, it is still turning on every time the door is closed. help!

SOURCE: Microwave still runs when door is open
Is this by any chance a combination microwave? It is is-what you are hearing/seeing is the fan running to cool it down. If it is not a combi then indeed you hav a problem-probably linked to the door catch.

Hi
It could be due to a faulty fan on your microwave, check whether the fan is running. Check and clean all the exhaust vents. If the fan is running then it could be due to faulty control board of the microwave. Hope this helps... Please post back with model# if you need more information.

SOURCE: Jenn-Air Microwave vent grill opens and closes
I have this same problem occasionally. Pull the vent grill open and look for a white cam that rotates when the microwave is on. To the right of that cam, there are two gray switches. The bottom switch should have a red tab that pops out. When the vent grill opens and closes continuously, the red tab is stuck in. Take a flat screwdriver or tooth pick and push gently in on the red tab to release it. It must get stuck due to grease or dirt accumulation. Good luck.
