Question and Answers

Q:

display fading in and out oven won't keep temperature 2784038891 Kenmore Kenmore electric built-in oven

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the display fading in and out and not holding temp. I know how frustrating that is.

Typically if a display is fading in and out, there is a loose wiring connection, an open wire, or an issue with the board. The lack of maintaining temperature could be an issue with the sensor or the board. It's recommended to first test the resistance of the sensor before replacing parts. At room temperature, the sensor should measure approx. 1100 ohms. If it checks out, a board replacement would be needed. 

In this case where the sensor is no longer offered, you could try running an online search for part number 334300 to see if there is one available in circulation on sites like Ebay. However, you would want to test it first to see if its the issue. If it checks out, there is more than likely an open wire or loose connection somewhere. 

In regards to the control board, we would recommend contacting Customer Care at 1-800-469-4663 to see what options are available. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Q:

F3 Code 278 4038891

A:

Thanks for the inquiry and for using SearsPartsDirect.com.
I am sorry to hear of the error code you've received on the unit, I know how frustrating that is to have occur.
The F3 error code indicates that you have a problem with the oven temperature sensor circuit. I recommend that you shut off the circuit breaker and check the resistance of the oven temperature sensor probe first. You can measure the resistance of that component using a volt/ohm meter. It should measure around 1100 ohms at room temperature (around 72 degrees). If the resistance is way off (by more than 100 ohms) then the sensor probe is defective. If the sensor reads between 1000 and 1200 ohms, it is good and your electronic control/clock is bad. 
Unfortunately, the oven temp sensor has since been discontinued for the unit and is no longer available for purchase through Sears. The part number was 334300. The electronic control is still available, and the part number is WB19X255.
If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, you can call 1-800-349-5071, or click here to be directed to the page to set up service.
