I have an old National NE-8060 Microwave Oven. First an issue which I think is now fixed. The oven would stop, even several times, during cooking. Had to press Start to continue. I cleaned all relay and door switch lugs and that seemed to have fixed the problem.
One more issue still remains. After cooking, open and then close door, the light, turntable motor and fan motor will run by themselves. Has to re-open and close door a couple of times before that would stop. 
All door switches and relays are tested fine. What could be the cause. Schematic and switches diagrams attached.

Thanks for the tip. I think you are right on the money. After cleaning the WD40 on the body of the door switch and area around the push button, problem goes away, at least for now. Will see if good luck will last.
