What the F3 error code actually means
The F3 error means your oven's control board is having trouble reading the temperature inside the oven because the temperature sensor is sending a faulty signal. This usually happens when the sensor has failed or its wiring has become damaged, causing the oven to lose track of how hot it actually is. As a safety measure, the oven shuts down the bake and broil functions until the problem is resolved.

First diagnostic step
Measure sensor value between connector pins: 1000 Ω at 32°F to 2697 Ω at 900°F (room temperature approx. 1080 Ω). If measurement does not correlate to real temperature, disconnect power and replace sensor. Also measure from sensor connector to sensor casing for possible short. Trace wires and connectors. Disconnect power longer than 30 seconds, re-apply and press BAKE and START/ENTER, observe for longer than 1 minute. If failure remains, replace control.

Questions people ask about F3
What does the F3 error code mean on a Whirlpool range?
F3 means the control board has detected that the oven temperature sensor probe is either shorted or open, meaning its resistance reading is outside the normal operating range. The board cannot reliably measure oven temperature, so it disables the oven heating functions. The fault can originate from the sensor probe itself, its wiring, or in less common cases the control board.
Is it safe to use my Whirlpool range while F3 is displayed?
The oven portion of the range should not be used while F3 is active. Because the control board cannot read oven temperature, it cannot regulate the heating elements, which creates a risk of overheating. Surface burners on a gas range may still function, but do not rely on the oven for cooking until the fault is resolved.
Can a bad oven sensor cause the F3 code even if the oven was working fine before?
Yes. Oven temperature sensor probes degrade over time and can fail suddenly or after prolonged heat exposure. A sensor that worked correctly for years can develop an internal open or short circuit, immediately triggering F3. This is actually the most common cause of this code, which is why Whirlpool's diagnostic process starts with testing the sensor rather than the control board.
How do I fix the F3 error code on my Whirlpool range?
Start by testing the oven temperature sensor probe. Remove the sensor from the oven cavity, place it in ice water at 32 degrees Fahrenheit, and measure the resistance across its terminals with a multimeter. A good sensor reads 1000 ohms plus or minus 20 ohms. If the reading is outside this range, replace the sensor. If the sensor passes this test, inspect the wiring harness for damage and then replace the control module if no wiring faults are found.
How much does it cost to repair a Whirlpool range F3 error code?
If the oven temperature sensor is the cause, the part typically costs between 20 and 60 dollars and is a common DIY repair requiring only a screwdriver and a multimeter. If the control board is at fault, parts range from 150 to 350 dollars or more depending on the model, and professional installation can add 100 to 200 dollars in labor. Testing the sensor first prevents unnecessary expense on the more costly component.
