Whirlpool Oven Error Code F3
Open oven temperature sensor — sensor circuit open
The most common cause of the F3 error on a Whirlpool oven is oven temperature sensor (RTD) failed open (~60% of cases); start with: power cycle.
What Does Error Code F3 Mean on a Whirlpool Oven?
Open oven temperature sensor — sensor circuit open.
F3 fires when the Electronic Range Control reads an open circuit on the oven temperature sensor (RTD) input — resistance appears infinite rather than the expected ~1080 ohms at room temperature. Without a valid reading the control cannot regulate bake or broil heat and locks out. It differs from F4, which flags a shorted or out-of-range (low-resistance) sensor, and from F2, which relates to over-temperature or keypad faults rather than a broken sensor connection.
What Causes Error Code F3?
Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Oven temperature sensor (RTD) failed open 60% of cases
- 2 Sensor harness/connector broken or disconnected 30% of cases
- 3 Control board sensor input fault 10% of cases
