Hello,

This error code on a Kitchen Aid range indicates a keypad short on the Electronic Range Control (ERC) board. This is the clock/timer on the operator console. The recommended fix is to replace the ERC. You can generally find replacement parts at these websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

All these sites offer great service with competitive pricing, so shop and compare.

Replacing an ERC is not a difficult repair and can be accomplished by the average do-it-your self offer. If you decide to order the part and wish to repair this on your own, follow these steps:

1. UNPLUG the range. Dangerous voltage is still present inside even with the range turned off.

2. Pull the range away from the wall and turn the unit around so you can access the rear panel.

3. Remove the screws on the back of the operator console.

4. Carefully disconnect the connector plugs to the ERC. Take note of how they are connected, so that you can reinstall them correctly.

NOTE: The connectors are usually color coded with the colors printed on the circuit board. However, if the colors are not printed on the board, write them down. (A digital camera also comes in real handy for this).

5. With the connectors removed, remove the mounting screws to the ERC and the assembly will come out.

NOTE: Most replacement ERC boards do not come with the overlay. This is the plastic pre-printed number display. The overlay can easily be peeled off and re-used. Just make sure you properly orient the overlay so that you don't inadvertently place it on the new board upside down. If your existing overlay is damaged, you will need to order separately.

6. Install new ERC using the steps provided in reverse order. Minimize handling the new circuit board with your bare hands to avoid damaging the board.
I hope this information helps you.


thank you for using fixya.

Will not operate. displays f2


F2 means you have a shorted membrane keypad.

On some models, you can get the membrane keypad replaced by a servicer or your can do it yourself, but on some models, you would have to order a new control panel frame which comes with a new keypad.

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.

Microwave will turn on by itself and display PAN on screen.


Does everything come on by itself or is it just a fan that comes on? If so, is it a convection oven?

63792 reports F2 error as well


An F2 error on these is a shorted keypad (either the main keypad or the transparent one in front of the tocuh screen). In some cases, this is a pretty easy do-it-yourself repair. Please contact me for an estimate and DIY tips.

NOTE: The FixYa system is not currently notifying me when folks reply to my posts, so please contact me directly for FREE help & do-it-yourself advice.

Kenmore microwave model 63792 displays F2 error message


The F2 error code on your microwave oven is a membrane failure.
It is recommended that you replace the membrane first & if you still have problems to replace the control board.

The microwave is displaying "-F2-" on its screen and will not otherwise work. What do you think the problem is?


It is a bad keyboard error code. Try this, unplugg the unit, open the control panel and disconnect the ribbon cable from the control board, plugg back in, if f2 comes back on the board needs replacing, if it does not, then the problem is with the keypad.
F2 means you have a shorted membrane keypad, which would have to be replaced.

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.
good luck

Model mh1150xms3 displays F2 and touchpad stops working


F2 on a Whirlpool microwave means you have a shorted 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 please do not leave it cooking unattended.

On this model, 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.

It's actually a pretty easy do it yourself job.

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.

Next, disconnect the strip as shown in the photo below, then remove the screws that hold your circuit board in the old frame.

Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of disassembly.

The part numbers to order are shown below by color you can get it here.

8185286 White
8185288 Biscuit
8185287 Black
8204739 Stainless

Display has a f2 code on it. whirlpool oven is model mh1150xm and less than 3 years old.


determined from whirlpool that the f2 display is from the control circuit board. the board's problem is intermittent and needs eventually replacing. not covered by warranty. determined that whirlpool has reduced the warranty for the electronic circuits in its appliances from 5 to 1 year. this is great for consumer confidence in whirlpool. have had trouble with 2 other new whirlpool appliances. probably will not buy another whirlpool appliance.

Kenmore microwave


If this has a controller that runs a microwave and an oven, then the problem F2 means a temperature related fault such as a bad temp sensor / thermostat or a defect in the control board. If it's just a microwave, then the problem is likely a failing keypad. In many cases, those can be replaced economically. If you repost with your exact model number (62622 is not a complete model number) then we can advise you further and more specifically.
