The microwave starts when the door is opened.
Answer Hello Joe,
You will need to replace all three door switches since they cause the complaint listed and if one has failed, the other two will fail soon and replacing them now saves the trouble of doing the job again.
My microwave surface light stopped working I put in a replacement bulb but the light does not turn off with the switch? What is the correct part to replace and any tips to replace it
If when you push the light button on the control to turn the light off but it stays on then the control board would have a stuck relay on it for the light. You would need to replace the control board for this issue.

Answer Hello Rick. One of the door switches are bad and you will need to replace the door switch on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
