"F2" on a Whirlpool means you have a shorted membrane keypad. It's not uncommon for it to be intermittent or partially operable, too.

On some models, you have to peel off the old keypad and stick on a new one.
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. It's here.

On 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 DIY job.

You can find helpful exploded view diagrams and order parts by entering your full model number (with suffix) 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.

If you have to replace the frame, you unplug the keypad (as per the photo below) and move the circuit board into your frame.

Microwave Model KHMS155LWH3 is showing a trouble code F-2 What does it mesn?

F2 is saying the key pad has a problem:
See this tech sheet:
https://www.servicematters.com/docs/wiring/Tech%20Sheet%20-%208205612.pdf

The touch/keypad can be found here: (Item 9) BLACK
http://forum.appliancepartspros.com/microwave-repair/19054-kitchen-aid-microwave-error-code-f2.html
I am assuming yours is white but the model number does not cross for some reason to a white control panel. When I cross it to your model it comes up Biscuit color ITEM 3 here:
($122.18)
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5133020&diagram_id=948095#d948095

I would check to make sure that no keys are stuck by rubbing your 1st finger FLAT across the membranes to unstick them and then check inside the unit to make sure the flexible ribbon connector is properly mated to the control board. Inside the unti there is usually a tech sheet inside the cabinet stored in a 4 X 6 envelope that may give you some insight on the keypad error. It should be Item 1 here as far as location only:

Kitchenaids microwave error message F2.Q1. What to

F2.Q1 Not reading keypad
inputs
1. Unplug microwave oven or disconnect power.
2. Replace the user interface board (UIB).
3. Replace the door control assembly.
4. Replace all parts and panels before operating.
5. Plug in microwave oven or reconnect power.

Many of the error codes may be solved by power cycling: unplug microwave oven or
disconnect power. After one minute, plug in microwave oven or reconnect power.

i found this info on a tech sheet hope this helps, let me know how it goes... some of those electronics had 5 year parts warranty i would check that out....Also u might be better of buying a new one if its out of warranrty as some of those boards are expensive, obvioulsy unplug unit first try to reset it self.

Mh1150xms-3 with f2 error

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.

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.

40716d4.jpg

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 number to order is 8205031 (formerly 8204739) and you can get it here for $140.37 plus shipping.

You can also find helpful exploded view diagrams at that link.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Microwave is beeping, lock comes on, F2, just keeps beeping by itself

F2 on a KitchenAid mike usually means a Keypad short. Beware if it is a KHMS155LSS, it can self start on its own with a KeyPad short. A real stunning defect.

Microwave mh1150xms-4 code f2

F2 on a Whirlpool is a failed keypad.

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. It's here.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should 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.

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

Please feel free to contact me directly if you need more help.

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.
