The microwave continues to run each time I close the door, despite the fact that I did not program any times.

1. Defective control board
2. Defective door interlock

this is a problem with your programme timer these can be expensive to replace and because of the age you will probably be better buying a complete new unit as you could repair it and you could come across other related problems and could end up spending a fortune sorry i couldnt be any more help

The door switch is adjustable. one or more need adjusting to solve the problem

Good Afternoon Friend,

I understand that your Frigidaire microwave continues to run, when you close the door and no time is set. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. Restore power. You might need to set your clock before doing anything else. Put a cup of water inside your appliance and try to heat it up. If you are still noticing your microwave continuing to run, even after no time is set, I suggest contacting your local authorized technician. Hope this is helpful.

Only time I have run into that problem, there was a bad micro-switch for the door. First thing make sure that you un-plug the microwave. You will have to take the outside cover off and look for a series of small switches mounted on a frame where the door latches. If you have access to a multi-meter you can check the switches for continuity. Easiest way is to remove that frame making sure that you mark or write down what color wires go each switch and then remove the wires. It may be immediately visible which switch is bad but if not check each switch with the meter. Your contacts will be a common terminal and either a normally open (NO) or normally closed terminal (NC) and sometimes both. The "NO" terminal will not have continuity until you press the switch button, the "NC" terminal will have continuity all of the time until you press the button. If you do not have any continuity at all or if you have continuity on one terminal no matter which way you push the button, that will be your bad switch. Hope this helps.

Probably a bad door switch or door switch mount. See help file here.

It's normal for a microwave turntable to run either direction at random. That's common in such AC motors.

Our microwave in office won't shut off. It continues to heat and fan is running as soon as we close the door. Tried everything, unplugged, canceled everything. Please let me know what to do.

Clear the cook cycle when you remove the food. Some microwaves pick up where they left off, so you don't have to keep pressing buttons.

Did you pressed the stop/clear button? or disconnect the micro.. for a couple of hours and try again?

This is usually caused by either a bad door switch, a loose door switch mount.

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.
