You need a new keypad. The keypads have tiny little traces that, over time, start lossing connection. Slaming the door causes them to make contact. There is not much more you can do. Let me know what the model number and brand is. Thanks for using fixya.

    Go to http://www.repairclinic.com/Home.aspx and put in you model number. I saw that they have 2 circuit boards for this model but one did not have a picture. You may have to call them to find out if they have the keypad or if it is even available. Other than that you can probably find it at Sears. I hope this helps. Thanks

I have a Frigidaire Microwave oven CFMV156DBA. The clock, lights and the keypad works. The turntable does not turn and it does not heat


This 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 only need a switch, you can order a universal type here for $5 postpaid.

Keypad Problems


Sometimes a keypad may not work because the door switches are faulty. When the door switches are working correctly it will allow the keypad to operate. They tell the microwave that the door is closed and the unit is dafe to use.

Many models have 3 door switches, it's wise to get all 3 replaced at once.

Microwave wont start


Assuming the Start pad on the keypad is good, I would strongly suspect the upper or lower door switch or the switch's mount, depending on your model number.

I've replaced the computer on my kitchenaid kems378gss3 oven/microwave combo. I need the "codes" to key in on the keypad - to make the microwave actually "cook: things. Everything else works...


If you don't have the owner's manual you can download it here:

Some units will not allow time programming if the door is open - or if the microwave thinks it is due to a bad door switch or door switch mount, etc.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

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.
