Kenmore Wall Oven error codes F3, F4, F5

I own a Kenmore wall oven model number 911-41065791 that is giving error codes (F3, F4, F5, etc.) Codes usually occur when baking for 10 minutes or more but are not consistent. We have used the self clean mode, but we have not been able to determine if this helps with the codes because the codes seem to be intermitant. We have owned this house since 2005 and never replaced any parts or had any service on this oven. Error codes started over 1 year ago and seem to be getting more frequent over the past year. Typically every other use at this point. If we shut the oven off and then restart, usually the code goes away at least to finish the current item being baked. What do these error codes mean and what do you suggest to fix it?

Those links for previous answers that Pvalde2 posted in the above response may help you with this failure. Those codes are normally caused by a problem with the oven temperature sensor probe. I recommend that you

shut off the house circuit breakers for the oven

and check that component first. You can access that component as shown in the image below. You can test it using the information in this video:

Oven Sensor Testing

. The sensor should measure around 1100 ohms at room temperature. If it is bad, it will need to be replaced. You can order that part from the

Sears PartsDirect

website. The part number is WB23T10002. Here is a direct link for that part:

Sensor Assembly

.

If that sensor is okay, then you could have a problem with that wiring harness or a bad clock control board in the console of the range. Reply with additional details if you need more help with this failure.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:

It seemed that my sensor probe was bad because it was reading 850 ohms at room temp, so I ordered a new one and replaced it today. I thought I was in good shape because it ran for about 35 mins at 350 degress but then I got the error code F3. I shut it off and restarted and got the same error F3 again. What should I do next?

That sensor probably was bad. It is a good sign that the oven initially heated properly to 350 degrees. You likely have a problem with the wire harness connection on that sensor probe or there is a possibility that you have a bad clock control board in the consol of that oven. You can SHUT OFF THE CIRCUIT BREAKER for the oven to disconnect electrical power and check that wire harness connection at the back of the sensor probe. If you are able to access the clock control board in the console, you can check the resistance of the entire sensor circuit from the connection on that control board. I provided a wiring diagram for that oven in the image below. That sensor circuit connects to the control board through white wires. If you measure the resistance through that circuit with the sensor plugged in and it is not around 1100 ohms at room temperature, then you probably have a bad wiring harness. The most suspect portion of that wiring harness is the disconnect plug at the back of the oven temperature sensor probe. You may be able to fix your problem by cutting that disconnect plug out of the circuit then stripping the wires and connecting them properly together using ceramic wire nuts. If that resistance through the sensor circuit is normal, then you will probably need to replace that clock control board. I hope that these additional tips help. If you need more assistance, let us know. NOTE: Be sure that you shut off the house circuit breaker for the oven before accessing internal components.

Thanks Lyle. I think it is the clock control board. Do you know that part number and how much it costs? Is this something easy like the sensor probe for me to remove and install? I'm starting to wonder if this oven is worth it or if I should look at something newer if the control board is expensive.

The part number for that clock control board is WB27K5273. That clock control board is no longer available as a replacement part. You would need to send that control board into a repair center to have it fixed. The cost for repairing that control board would be around $150. Core Centric Solutions is the company that is set up to repair that control board. I provided a link for that company below this response. You can use the contact information from that website to arrange the repair of that control board if you decide to fix the oven instead of replacing it. Be sure that you shut off the house circuit breaker for the oven before removing that control board. NOTE: Based on the age of that oven and the availability of replacement parts, I recommend that you seriously consider replacing it instead of completing this repair. You can view current oven models on the Sears.com website. Let me know if you need more help.

We own a Sears Kenmore oven, Model # 911.41065. It was in the house which we purchased in 2008. We have had no problems with it until 3/19/14, when in the process of baking some chicken at 425 degrees, it abruptly stoppped working, flashing a red F7 sign with a beep. On resetting, the beep stopped, and the red sign disappeared but the time on the clock was replaced by a green F4 sign. The clock resumed display on resetting, but shortly the beep and flashing red F7 started up again. The only way to stop this was to turn off the system by way of the circuit breaker. We let it cool for over an hour, then tried to restart. we got the same response as above!

Any suggestions?
