Dec 23, 2021 - The Ge Wall Oven F4 Error Code is an oven temperature sensor fault. It means the temperature sensor is shorted (under 950 ohms). The temperature ...

Fix it because it need repair

F4 is a temp sensor error. you can find more info here

Hello,

When checking the sensor it shouls be checked at room temp (even if power off) at it should be between 1060-1100 ohms at room tempature. 16 ohms the new sensor is shorted the F2/F3/F4 all relate a faided sensor and the F5 error code says the clock (electronic oven control) is defective.

Test the sensor again at room temp...if only 16ohms its no good and will throw the F4 code everytime again a good sensor measured at room temp should be between 1060-1100 ohms

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.

Hi, replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.

Hi, the F4 error code means Open or shorted oven temperature sensor (RTD)..
Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

I dislike new electronically contolled ovens so much. Electronics are never meant to be near temperatures reaching more then 200 degress.
F3 or F4 Open or shorted oven temperature sensor Replace oven temperature sensor

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.

Mewood What part did you call "thermostat"? If you?re talking about the device which operates the oven temperature, your oven does not have such thermostats. It has two oven temperature sensors (one in each oven) and a control board (ERC). An error code "F4" will be displayed along with a beeping sound if the ERC determines an open oven temperature sensor circuit. It can be the sensor itself or the wires that connect the sensor to the ERC. The F4 message will not be displayed in the time of day mode. To get access to an oven sensor and wires, the oven has to be removed from the cabinet. Then you have to remove the rear cover. Then unplug the oven sensor and check the resistance across the oven sensor. It?s supposed to be about 1100 ohms at room temperature. If the resistance is incorrect, the sensor is bad and needs to be replaced. If not, check all the wires from the oven sensor to the ERC. If it is not the sensor and wires, you have to replace the ERC, but most likely the problem is with the wires and/or connections. Part number for ERC is 62965, part number for oven sensor is 62593.
