Whirlpool Cooktop Error Code F3-E0

The F3-E0 error code on a Whirlpool cooktop indicates that the main oven temperature sensor (RTD sensor) for the upper oven has been detected as either open or shorted. The control board continuously monitors the resistance signal from the oven temperature sensor to track cavity temperature and regulate the bake and broil elements. When the resistance reading falls outside the expected range, either reading near zero ohms (a short) or showing no continuity at all (an open circuit), the control interprets this as a sensor fault and triggers F3-E0 to prevent unsafe oven operation.

The oven temperature sensor is a resistance-based probe mounted inside the oven cavity, typically near the rear wall. Under normal conditions, the sensor resistance changes predictably with temperature. At room temperature, roughly 50 to 90 degrees Fahrenheit, the sensor should read approximately 1080 to 1090 ohms. An open circuit reading or a reading near zero ohms points directly to a failed sensor or a wiring problem between the sensor and the control board connector P10. Corrosion, heat damage, or a pinched wire in the harness are frequent contributors to this type of fault.

Diagnosis begins by entering Diagnostic Mode using the CANCEL, CANCEL, START sequence, then confirming whether the sensor temperature display reflects a reasonable room temperature reading. If the reading is absent or extreme, the next step is to inspect the sensor connector at P10 for secure seating, corrosion, or damaged pins. If connections are intact, the sensor itself should be tested with a multimeter to confirm whether it is open or shorted before replacing components.
