Kenmore Elite electric range Model 911.99002990 with F4 code and beeping. What does it mean?

Periodically, when I use my oven, it starts beeping and displays an F4 code. Turning the oven off and on again usually works. What is the problem? Can I fix it myself? How expensive is the repair?

The first link that Barbara H. provided in the above response correctly identifies the F4 as indicating that you have a problem with the oven temperature sensor probe. The first image below shows how to access this component.

Unplug the range

to disconnect electrical power before accessing internal components.

If you have a volt/ohm meter, you can check the resistance of the oven temperature sensor probe. It should measure around 1100 ohms at room temperature. If it measures less than 950 ohms, then this is the failed component that is causing your F4 code.

You can order the sensor from the

Sears PartsDirect

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

Sensor

. This part costs around $40.

If the resistance of the sensor is okay, then you could have a wiring failure or a bad electronic oven control board. You can plug the sensor back in and check the entire sensor circuit from its connection to the electronic oven control board in the console (with the range still

unplugged

). The second image below shows the wiring diagram for this range with the sensor circuit circled in red. To access the control board,

unplug the range

and remove the back panel behind the console. Unplug the connector for the sensor circuit from the control board and measure the resistance through that circuit using a volt/ohm meter. If the resistance is the different than what you measured directly at the sensor probe, then you apparently have a problem with the wiring harness between the control board and the sensor.

If the resistance through the wires that connect to the control board is the same as the measurement at the sensor (around 1100 ohms), then a bad control board is likely causing this problem.

An intermittent problem may be difficult to diagnose.

If you need more help, reply with additional details and we will assist you further.

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:

Sears Home Services

. A repair visit will likely cost around $130 for labor. The parts would likely cost between $40 and $150.

Diagnosing all the error codes that the modern appliance displays can be confusing. I found a similar question from a previous expert post that may answer your question. If you decide you prefer to have an experienced technician make repairs and do the further testing, an option is to visit Sears Home Services and use the handy scheduler. I attached the links below. Hope this helps!
