Question and Answers
An error code can stir up many concerns. I researched your question and found someone with a Kenmore oven had the same question about the f3 error code. An expert posted a very helpful link. I have provided the link below. I hope this helps!
The answer from Jacqueline S has good information for testing the sensor. Here is a different approach to the same problem.
The F3 error code can be caused by either the ERC (electronic range control), or the oven temperature sensor. You can't test the ERC (electronic range control), but you can test the oven sensor. Begin by disconnecting the power to the range and removing the rear panel covering the ERC. Remove the lower panel from the range and follow the oven sensor wires up to the control. Disconnect the plug on the ERC containing the oven sensor wires and read the resistance of the oven sensor. It should read between 1000-1200 ohms.
If the oven sensor tests within this range the ERC is defective. If it tests out of the range disconnect the wires from the oven sensor and measure the resistance of the oven sensor. If it tests out of the range the oven sensor is defective. If it tests within the range the harness between the ERC and the oven sensor is defective.
