Key pad stuck

If you have already tried turning off the breaker and following the steps in the manual, it's possible that there is a problem with the oven's control panel or the temperature probe itself.
Here are some additional steps you can try:

1. Unplug the oven and wait for a few minutes before plugging it back in. This may reset the oven's control panel.
2. Check if the temperature probe is inserted into the oven. If it is, try removing it and see if the oven turns off the probe function.
3. If the problem persists, you may need to contact a professional technician to diagnose and fix the issue.
4. If the oven is still under warranty, you can contact the manufacturer or retailer to request a repair or replacement.

It's important to be cautious when attempting to fix any electrical appliance, so if you're not comfortable with troubleshooting or repairing the oven yourself, it's best to seek professio

sounds like your probe connection may be shorted. Can you inspect the probe itself, and perhaps do a test for continuity with an ohm meter? Also, you might be able to disable the probe in the menu settings, and run it on manual, just for a test.

Do you still have the user's manual for this unit?

I had another brand with that fault from new. We disconnected the probe wiring from the control board and it stopped looking for it.
Also, could be a setting has been changed inadvertently.

I suggest you contact this appliance timer repair company
They can tell you over the phone whether this is likely something that they can repair. If it is repairable, you just remove the timer, send it to them and they repair it and send it back for $106 plus shipping. There is no charge if they can't repair it.

Hi,

Here is what Kitchen Aid says about F4:

F4 Meat probe shorted
1. Disconnect meat probe and measure probe resistance (78kω at 60° F [15.6° C],
37kω at 90° F [32.2° C]).
2. If resistance is not valid replace probe.
3. Insert probe and check for a firm connection between probe and jack (in oven cavity).
4. Check connection between jack and harness (in rear of oven).

It sounds like the probe jack may be bad or the wiring between the jack and the control board above.

I had a similar problem today with my KitchenAid Superba wall convection oven (2002 model). I was roasting tomatoes at 225 degrees F for 3 or 4 hours when the control pad changed and showed that the probe was in use (never have I used it and had to look for it). I, too, tried to plug in the probe and take it out, but nothing changed. My worry was that I could no longer use the timed bake function. After trying to reset by turning off the oven at the breaker, with no change, I turned on the oven to 400 F and left it on for 10 - 15 minutes hoping that the high temperature would dry out whatever moisture that must have gotten in the place where the probe connects. Then I turned it off and just waited. After a half hour or so the control pad cleared and nothing showed (that is what you want when the oven is off!). Everything is back to working now.

F7 indicates a stuck touch pad key. Try pressing all teh buttons on the key pad to see if one is stuck. If you don't have a stuck key, there may be a problem with the key pad module itself

Press "0".

The fault code "F0" is indicating a possible stuck or shorted key pad or oven control board failure.
Determine if the problem is with the key panel or the oven control board by:
1. Pushing Clear/Off pad.
2. Disconnecting the Ribbon Cable Connector from the control board and waiting at least 32 seconds to see if the Code recurs.
If the code recurs, problem is in the control. Replace control.
If the code does not recur the problem is the Key panel and it would need replaced.
This test is normally done by an experienced service technician to avoid any possibility of getting shocked. This has to be done with voltage applied to the wall oven. Extreme caution should be exercised while testing.
I recommend calling a service technician to diagnose and repair your oven.

It seems you have a stuck button. Here is a list of fault codes:
