So the oven lamp comes on but the turntable and internal cooling fan do not?

If that is incorrect, please reply back and correct me.

If that's the scenario you have, then you have a bad primary interlock (bottom door switch) or its mount is broken or loose.

We have the service manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

You will need the
free Acrobat Reader to view or print it in case you don't have it already.

The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

My microwave stopped working you can input time but when you push start nothing happens it has power and everything just will not start its like the start button does not work


Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.


There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

If the timer counts down and nothing else happens, the secondary interlock switch is bad. This switch completes the cook circuit and this is why it doesn't run. You need an ohm meter to diagnose and find the right switch. Switch failure is caused by opening the door when it is in cook mode. Push the stop button first before opening the door and this failure will cease to occur. BE CAREFUL !!

No! The problem is one or two bad door switches, or possibily the keypad control board.

The timer counts down but the microwave doesnt turn on.


I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.

Stops cooking


This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

Frigidaire won't run


Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
