    Exactly the same problem. My microwave continues to beep and displays an F 2 error message. What should I do? Thank you!

  • Anonymous Nov 16, 2008

    The microwave beeps on its own then locks itself. Sometimes the F2 message is displayed. It's not frequent, but started this about a month ago.

    This is a great site!! Thanks!

    I have the exact same problem - Fault #2. I believe it's the control panel that's malfunctioning. I had to resort to unplugging the microwave also.

  • Anonymous Dec 06, 2008

    Our Kitchen Aid oven touch pad will intermitantly (two or three times a year) malfunction by going into LOCK MODE, become inoperable and BEEP.It will not unlock using the manuals instuction guide by pressing and holding the 0 pad for three seconds.If the 0 key pad is depressed for 20 or 30 seconds it will LOCK ALL key pad functions and flash a E-2 message. The only way to get it operable again is to unplug it for a few hours (overnight) and it will function again. I am now awaiting service from my exteneded warranty policy provider in hopes they will replace the complete touch pad assembley.Always assumed that Kitchen Aid was a superior product but that mith has been shattered.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here:

I'd say you have a contaminated or failing keypad or possibly residue on the boar dor where the keypad connects to the board.

Is it possible that some spray cleaner got into the controls?

I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.

Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

We're happy to help and we appreciate your thoughtful rating of our answer.

Microwave was beeping a single beep once in awhile now nothing happens but the clock still works

A lot of the time when that happens the touch pad is bad and may have a colappsed air pocket on a pad. ( it makes the unit think you are pushing a pad ) The only way to fix it is to replace it (the touch panel) . Did you see any numbers coming up in the display. Like if the 3 pad was bad and making it beep it may have been showing a 3 in the display,. Always possible it could be a bad main board. But most commonly I have found it to be the touch panel. Try to unplug it and then plug it back in and try to set the clock. when you do, try each number pad and see if they all work. See if any feel different.

Error code F2

Per the tech sheets (page 8), "F2" error code means "Keyboard failure". Recommended by the manufacturer to replace the touch panel first and, if it would not solve the problem, then the control board has to be replaced too. Not the best recommendation but we have to follow it.

- The part number for the touch panel (aka a membrane switch) is AP3130765

- The part number for the control board AP3130764

Operation manual is lost, how do I set the clock?

The manual for the Magic Chef MCD1311ST Microwave can be downloaded in pdf format from the following site (follow the link then click the "Manuals" tab):

If you don't have time to download, here's what the instructions state:

When the oven is first plugged in, the display will flash ":0" and a tone will sound. If the AC power ever goes off, the display shows ":0" when the power comes back on.

1. Touch CLOCK pad.
This is a 12 hour clock system.

2. Touch CLOCK pad once more.
This is a 24hour clock system.
NOTE: This oven has multiple clock system. If you want 12 hour clock system, omit this step.

3. Enter the correct time of day by touching the numbers in sequence.

4. Touch CLOCK pad.
The display stops blinking, and the colon start blinking. If you selected 12 hour clock system, this digital clock allows you to set from 1:00 to 12:59. If you selected 24 hour clock system, this digital clock allows you to set from 0:00 to 23:59.

5. Touch STOP/CLEAR pad.

NOTE: If you attempt to enter an incorrect time, the time will not be set and a error signal tone will sound. Touch the CLOCK pad and re-enter the time.

F2 E0 "Stuck key" ????????????

F2-E0 - Shorted Touch Pad (Keypad) - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure.
Select the 'cancel' function and wait 60 seconds.
If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
