Question about Frigidaire FMV156DC Microwave Oven

1 Answer

Door closure does not activate microwave

If I strongly hold the door upwards, then only will the microwave work.
How can I get it to work automatically as it once did. It was installed in 2004.

This is caused by either a bad door switch or 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.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

My GE XL1400 over-the-range Microwave does not power on to cook. The inside light will not turn off when the door is open or closed. Unplugged and re-powered with no change....where to start?


Easy....the reason the light does not go out when the door is closed and the microwave gun is not activating...is due to your door switch not "sensing" it being closed. Sometimes there two electrical switches on the door...yours probably have one and the actuating arm...metal tab on the switch is probably bent and need to be re-bent to sense door closure. Take apart the microwave and re-bent this switch tab...it's relatively easy to find and correct. The door switch might be bad too...won't cost much. 9 times out of 10 it's a bent switch bar.

Hello estela281 :

Your microwave problem could be happen because of a bad door switch or loose door switch mount . There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly .

That could happen because of slamming the door and not closing it gently .

WARNING : A microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. I strongly recommend you seek the assistance of an appliance repair technician when conducting any microwave oven repair .
