Why does my Kenmore oven show the F3 error code?

by Manage My Life Last activity date:
December 10th, 2007

I have a Kenmore range model number 790.75761002. It has serial number SVF05102795. I started the clean cycle on my oven. The light came on and shows F3. The oven door will not open. The F3 flashes on and off with a buzzing sound. The range has been unplugged for 48 hours. I still can't get the door open. I can only cook on the stove top. When I am using the cooktop, the oven buzzes and the oven door cannot be opened.

The F3 error code indicates that the EOC (Electronic Oven Control board) senses a problem with the oven temperature sensor. You could have a defective sensor, a failed EOC or a bad wiring connection between these 2 components.

Normally, a technician is needed to diagnose and repair this type of failure. The technician would unplug the range and access the EOC in the console. He would pull the 15-pin plug from the EOC and measure the resistance between pins 12 and 13 of the plug. This would check the temperature sensor and connecting wiring. The tech should measure about 11000 ohms at room temperature (75 degrees Fahrenheit).

If this reading is good, the EOC would be the failed component and would need to be replaced.

If the resistance reading of the sensor circuit is bad, the reading would be taken directly from the leads on the temperature sensor. If the resistance reading taken directly off the sensor is bad, then the temperature sensor has failed and would need to be replaced. Otherwise, the wire harness is the failed component.

If you have a volt/ohm meter and the technical expertise to safely access and test internal components of your range as described above, you may be able to diagnose and repair the range yourself. If you attempt this repair and need additional assistance, resubmit your question for more help with this problem.
