Question about Frigidaire FMV156DC Microwave Oven
The timer will run when you push start but the microwave doesn't cook. Used to when you adjusted the door, but now it does nothing. How, or, who can I call, to fix this? I haven't had the microwave for 2 years yet.
is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually 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.
If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.
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.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
If you don't find yours, or if you want to look at it without disassembling the oven, you may be able to download it here.
If you only need a switch, you can order a universal type here for $5 postpaid.
