Kenmore double oven f4 fault code - door locked.

I self cleaned my kenmore oven and everything was fine. It finished cleaning and the fan was running when I left the house. When I got back it had an F4 fault code and the door was locked. I cannot get the door to unlock. (I found the repair parts guide for my double oven and it lists the model numbers as 911.4942590 or 911.4942990. Since the microwave has the model number of 911.4942590, I am assuming that the other model number is for the oven.) How do I get the door unlocked? From everything that I have read it seems that the heat sensor has shorted out, but I can't get the door open in order to get at the part. Please help e as I am about to go crazy. It is the baking season and I can't bake! Thanks, Janet

    Thank you. With this advice and a little tweaking, I was able to get the door open. Will the lock reset once I replace the sensor?

    I have the same problem, tried to clean oven and door is stuck locked and getting F4 and F8 message....what can I do?

  • featherbrain Mar 03, 2009

    I bought my unit used, installed it and from the get-go am getting the F4 fault. So I have tried finding a place to buy this sensor but even Sears acts like I'm speaking Greek. What is this part called and where on the oven is it actually located?? Maybe if I found the part on the oven I could get a number off it to research and try to find....Thanks!

We had the F4 problem and called Sears repa. They sent someone out. The guy opened the panel above the bottom oven (we have a double oven) and hit a reset button - then charged us $75. This has worked on several occasions (my husband did it after that). But then that didn't work and Sear's told us it was the electronic panel which they replaced twice. Now it's (F4) happened again on the top oven only on a brand new electronic panel. So I guess it's the heat sensor this time.

The perfect tool for this is a locksmith's "slim jim" but for the rest of us try this: Make a small hook in a wire coathanger and slip it between the door and frame from the left and try to catch the hook in the latch mechanism. Use a small mirror for navigation. Pull just enough to release the door.

    You shouldn't get the error code after you replace the sensor. Then if you need to, put it in clean, wait 30 seconds then cancel it. That should reset the mechanism

SOURCE: f4 error code

Ok, test the element for its operational value. if the element is not getting a signal to warm from the control board, this will be the issue, considering that the element is new and able to warm. replace the Oven control in this case.

JUst to be safe, back track the installation to make sure every connection was properly united. make sure the element was installed correctly. if so, replace the control.

SOURCE: Kenmore ovens flashes -F4- when I try to set it to


The problem likely originates from the oven temperature sensor. While not all but most manufacturer's use the "F4" code for a shorted or open sensor, you'll need to provide your model number to be certain. If you are able, check the value of the sensor, it should be approx. 1100ohms at room temperature, if not, replace it.

**Unplug the unit from the wall before performing any service**

hope that helps,

Good Luck :)

F4 usually relates to a temperature sensor fault. Meaure the temp sensor at ambient temp and it should measure approx. 1K . If it doesn't, then replace. However, and a big however, I've seen frequent faults such as these where the control board is at fault. The proper procedure is to verify the sensor though first before replacing control board.

What does error code F-90 mean on a Kenmore delf cleaning wall oven

The F90 error code indicates that the door unlock time exceeded. This will happen if the lock is in the locked position with the oven door open or if the lock motor fails. Have someone hold in the oven door light switch while you set the control up for the self-cleaning cycle. Let the self-cleaning cycle run for only 4-5 minutes then press stop/cancel. This should allow the lock assembly to reset & retract the door lock back into the unlocked position.

You can also try resetting the appliance by disconnecting it from the outlet or switch off the circuit breaker for 20-30 minutes. Once power is restored run a test cycle. If this does not work I suspect a door lock assembly failure. This type of diagnosing will require accessing the lock assembly & using a volt/ohm meter for testing

I have an older model double oven by Kenmore - probably 15-18 years old. I was baking bread in foil three days ago and the oven set on bake 325 degrees. (I had been cooking a roast in it for several hours...


the oven may have locked in consequence of the self cleaning cycle.

After unplugging, allow the oven cooling down for few hours.

If the is still locked, then the high temperature generated in self cleaning cycle may have damaged temp probe, door latch, or electronic control.

Parts must be tested to discover the fault.

Call Kenmore at the number listed on the owners manual.

Oven door will not unlock

Hello,, Some times this will happen after a self clean cycle if the timer did not finish the entire clean. Try to set the clock to start the self clean again then simply end the self clean. This should unlock the door. If the door remains locked. You may check the oven for an error code, or the door latch itself may need to be replaced. One other possible would be to turn off the power to the oven and try to let the oven control reset. leave the power off for about 15 minutes then turn the power back on. That will sometime work aswell. Good luck and feel free to call me if you need more help.

Self cleaning oven directions

Press the self-clean button.  The panel becomes blank(---), then press the up arrow( ^ ).  The panel will appear 3:00 (indication for the duration of self-cleaning). The oven will lock on its own and start the self-cleaning.  Good luck, ya'll!
