Question about KitchenAid KBMC140HSS Convection/Microwave Oven
When attempting to start the microwave using EasyMinute Start button, the microwave beaps three times and won't start. If I set the timer and press Start, the word DOOR is displayed on the front panel and the microwave beeps 3 times and does not start. How is the door open indicator detected? I replaced the electronic control panel but that did not work.
This is usually an indication of a bad door interlock. Take resistance readings with the power turned off on the primary and secondary interlocks. You will need to remove the control panel to access them. There should be a wiring diagram somewhere inside the control panel to assist you in determining if the interlock is normally OPEN, or normally CLOSED. As you open and close the door the interlock should change states. Additionally, double all your connectors to make sure they are plugged in correctly. I had a similar problem once and it turned out to be a loose connection on one of the interlocks. I hope this helps you.
