Occasionally, when the microwave turns off or we interrupt the time, we remove the food and shut the door and the microwave light, turntable, and fan begins running on it's own. The clock is displayed (so there is no time remaining) or if we interrupted the cycle, the time remaining is displayed without counting down. We have found that we have to open the door (to stop it because the "clear" button doesn't work) close it again and that usually corrects the problem.
This is usually caused by either a bad door switch, a loose door switch mount, or occasionally by a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.
We're happy to help and we appreciate your thoughtful rating of our answer.

Door switches
If one of the door interlock switches
is not switching properly or there is a condensation problem on the
sensor control panel, either can cause the turntable/light/oven to
come on even though the "Starts" button has not been
depressed due to the wiring of the switches.
Check for faulty door
switches and/or contaminated actuators.
I hope that helps.
