F4 error code on Jenn-Air W30400BC expressions built in oven

Hi,
i have posted this tip that explains what the F3(and F4) error code means and what to check to fix your oven

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. This is a failed oven temperature sensor error code. Simply replace the temp sensor, asap. This will clear the code. The temp sensors are generally located inside the oven, mounted on the back wall, in the top left or right corner.

It will look like a 4 inch slim probe.

F4 failed temp sensor.

HI thanks for your question. the code F 4 means an open temp sensor. which is located in the oven , top left corner. replace the oven sensor. thanks the appliance doc. please rate my answer. thanks

no adjustments hinges are mounted inside door panel right?check to make sure theres no damage to inner door panel

just scroll down on this e mail and in the comment box you can answer my question

What problem are you having with the oven and are there any error codes?

It seems you have a stuck button. Here is a list of fault codes:

JENN AIR
Range/Stove/Oven Fault Codes
Failure
Code Condition Check/Repair F1 Defective touch pad or membrane Replace touch pad or membrane (this problem is usually the touch pad) F1 Watchdog on board Replace touch pad or clock assembly (also called the ERC) F2 Oven too hot Replace relay board (if present) or oven temperature sensor F3 or F4 Open or shorted oven temperature sensor Replace oven temperature sensor F5 Hardware and watchdog circuits disagree Replace clock assembly (also called the ERC) F6 Missing AC signal Check for proper voltage F7 Function key shorted or stuck button Replace touch pad or clock assembly (also called the ERC) or attempt to un-stick button F8 Analog/Digital supervisory Replace clock assembly (also called the ERC) F9 Door latch supervisory Check door lock circuit or replace clock assembly (also called the ERC) F0 Function key stuck Replace touch pad or clock assembly (also called the ERC)

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

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.
