Hello. My name is ***** ***** I'll be helping you with your appliance question today. Please wait a few moments while I review your question.

Expert:  Tyler Z. replied 3 months ago.

The fact that the microwave is running when the door is closed and it's not heating mean that one of your 3 door switches has failed. There are 3 door switches for safety reasons and if one of them is acting up you get this symptom so you need to determine which switch is faulty and then replace the faulty switch. Below is a video on how to test door switches if you have a multimeter to test the switches. Just replace the faulty switch and you should be good to go again.
