Kenmore microwave Keypad display shows -F2-. Unplug unit for 20 minutes or so and microwave will work fine for a short time. Keypad display then goes back to -F2-.

Here is a previous answer that might be of help.......

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If it is still locked or goes into lock mode by itself, the "clear" key on your keypad may be shorting.
Here's how the child lock works on model FMV145:

Child Lock-Out
You may lock the control panel to prevent
the microwave from being accidentally
started or used by children.
To lock or unlock the controls, press and
hold CLEAR/OFF for about three
seconds. When the control panel is
locked, an "L" will be displayed to the
extreme right.

SE is an error code for a shorted keypad, although the keypad might not really be shorted.

Unplug the oven for a few minutes to see if it clears the error code. If not, then leave it unplugged over night. If the problem persists, then you probably do have a shorted membrane switch on the keypad.

"F3" on a GE / Hotpoint microwave means you have a shorted membrane keypad.

On RVM1435-series microwaves, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.


In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.
You can find helpful exploded view diagrams and order parts by entering your full model number (RVM1435XX###) from the tag on the oven here.

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.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.




Some connectors on the relays have a lock:

F2 on a Maytag / Kitchenaid / Whirlpool model means you have a shorting membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

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.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

But please note that for some models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

Please contact us with your full model number and we can tell you if yours is one of these models, and if so, we'll also give you the part number you need to order and a link to the best priced supplier.

Either way, we can let you know what your options and costs would be and send you other helpful info.

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.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
