Oven comes on then beeps and a code F4 comes on

Could be control module, but not sure. I had issues with a code a long time ago, and the broiler kept coming on and wouldn't shut off, so finally had to shut it off at the breaker. Turns out the control module is fried. But just a thought.

Hi

F4 Error indicates a loose/broken wire on the oven temp sensor or the oven temp. sensor itself is bad and should be replaced. To solve this issue test the oven temp. sensor, it should read between 1080-1120 ohms, if the rating is more then that and the door appears to be closing fine then it is the control board that is bad and should be replaced. Hope this helps...please post back for further assistance.

Hello & Welcome to FixYa

F4 error code indicates a open/shorted oven temperature sensor and to solve this problem the sensor needs replacement. If you wan to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more then this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. However, I believe it is the sensor as the problem is only with bottom oven. Please get back to me if you have any other questions.

F-2 is shorted or stuck keypad.
F-4 is meat probe shorted.

Your temperature sensor is inside the oven in the top rear section. It is metal about 3 inches long. You can remove it from inside the oven. The F2 and F4 codes is a bad temp sensor.

Sorry to say you will need an engineer to check the heat sensors as they may be faulty

Replace the oven temperature sensor. It is located in the back wall of the oven. 4-6 inches long,up high on the right or left side depending on model. Most can be changed from inside the oven rather than through the back.

Slone, F4 is the code for a shorted temperature sensor. This is the temp probe in the oven. There are 2-quarter inch screws holding it on. It should pull out through the insulation until the quick connect comes through. If you want to make sure, the sensor should ohm out at 1143 ohms at 100 degrees. I think you can be pretty sure that this is the problem. The part number I have is 704657. Catriver.

f4 means it has a shorted oven temp. sensor and will need to be replaced.
