F3E0 Oven temperature sensor open circuit
The Whirlpool F3E0 error code on your oven indicates: Oven temperature sensor open circuit. This typically requires troubleshooting the temperature sensor system.
What Causes This Error
Faulty temperature sensor/thermistor
highThe sensor has drifted out of range or failed completely, sending incorrect readings to the control board.
Damaged wiring to sensor
mediumThe wire harness connecting the sensor to the main board is pinched, corroded, or disconnected.
Control board malfunction
lowThe main PCB is not correctly reading the sensor signal, even though the sensor itself is fine.
How to Fix Error F3E0
- 1
Power cycle the appliance
Unplug it from the wall for 5 minutes, then plug it back in. This resets the control board and clears transient errors.
- 2
Locate the sensor
The oven temperature sensor is a metal probe usually located at the top rear of the oven cavity. It has two wires connecting it to the control board through the back wall.
- 3
Inspect wiring
Look for pinched, burned, or disconnected wires between the sensor and the control board. Reseat any loose connectors.
- 4
Test the sensor with a multimeter
Disconnect the sensor and measure resistance. At room temperature (~77°F), most thermistors read 3,000-10,000 ohms. If it reads 0 (short) or infinite (open), it's failed.
Unplug the appliance before testing electrical components. - 5
Replace the sensor
If the reading is out of spec, order a replacement thermistor for your specific model. Installation usually requires only a screwdriver.
Replacement Parts
If the steps above don't fix it, you may need one of these parts:
Oven Temperature Sensor Probe
$15-$45Sensor Harness
$10-$25When to Call a Professional
If the error persists after replacing the sensor, or if you're uncomfortable working with electrical components
- Control board diagnosis requires specialized knowledge
- Intermittent sensor faults can indicate deeper wiring issues
- Incorrect diagnosis could lead to unnecessary part replacements
