I have a Samsung Model SMH1713 Microwave that keeps the fan and light on when you close the door when not cooking. We are unable to close the door when not using it. I have checked all the switches for the door, the 2 TCO's behind the keypad (one is normally open and one is normally closed) and the fuse. Microwave functions normally but when you close the door it acts like it is cooking. I have verified that it is not cooking and it appears just the light and cooling fan are running.
Any ideas? Magnetron replaced in Feb., 2014.
I have search the forum already to no avail.
