Whirlpool Range Error Code F3E3

F3E3 means the LCC or LCX control board detected that the oven cavity exceeded the maximum allowable temperature during a self-clean cycle. The control stores this code and shuts down the clean operation as a protective measure. The most common causes are a failing oven temperature sensor or a wiring connection problem between the sensor and the control board.

Normal baking and broiling functions may still operate, but you should not run another self-clean cycle until the F3E3 fault is resolved. The code indicates a temperature monitoring problem during cleaning, and running self-clean again risks damaging the control board, door latch, and oven interior due to uncontrolled or falsely measured temperatures. Using the stovetop burners is generally unaffected by this fault, but resolve the underlying issue before using the oven's clean function.

F3E3 is stored as a persistent fault code in the LCC or LCX control system and will not clear simply by letting the oven cool. You can attempt to clear it by pressing CANCEL, but the code will return during the next self-clean cycle if the underlying cause, such as a faulty sensor or bad wiring connection, has not been corrected. Diagnose and repair the root cause before attempting another clean cycle.

Start by pressing CANCEL>CANCEL>START to enter Diagnostics Mode and confirm the fault code and live sensor temperature reading. Unplug the range and inspect the wiring harness connections at the oven temperature sensor and at the control board for burns, corrosion, or looseness. Test the RTD sensor with a multimeter; it should read around 1080-1090 ohms at room temperature. If the sensor is out of range, replace it. If the sensor tests good and connections are secure, the LCC or LCX control board may need replacement.

If the oven temperature sensor is the cause, the part typically costs $20-$50 and replacing it is a manageable DIY repair requiring only a screwdriver. If the LCC or LCX control board is at fault, the board can range from $100-$300 depending on the specific model, and professional labor adds $100-$200 on top. Checking wiring connections yourself first costs nothing and can resolve the fault without any parts.
