Jenn-Air Range F3-E0 Error: Oven Temp Sensor Open

What Does Jenn-Air Range Error Code F3-E0 Mean? Error code F3-E0 on a Jenn-Air range indicates the oven temperature sensor has an open circuit. This sensor — a resistance temperature detector (RTD) probe mounted at the top rear of the oven cavity — is essential for temperature regulation during baking, roasting, and broiling. Common Causes […]

Quick Assessment

Answer to continue safely

Is it safe to keep using?

No. Without a working temperature sensor, the oven cannot regulate heat and could overheat. Do not use the oven until repaired. Stovetop burners are unaffected.

Can I reset the code?

Yes. A power cycle will clear the error temporarily, but it will return as soon as the oven attempts to heat.

When to stop immediately?

Stop if you notice: Oven does not heat at all, Temperature reading is clearly wrong.

Symptoms You May Notice

Oven will not heat at all

The oven refuses to start a bake or broil cycle because it cannot verify the temperature.

Oven shuts off shortly after starting

The heating cycle begins but cancels itself within a few minutes.

Temperature display shows abnormal reading

The display shows an extremely high or low temperature that does not match reality.

Possible Causes

1

Failed temperature sensor (RTD)

The resistance temperature detector probe inside the oven cavity has an open circuit from a broken wire or failed element.

Requires Professional
2

Disconnected sensor wiring

The wire harness from the sensor to the control board has come loose or a wire has broken.

DIY Possible
3

Corroded sensor connector

Heat and moisture have corroded the plug connecting the sensor to the harness.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Inspect sensor connection

    The oven temp sensor is a thin metal probe at the top-rear of the oven cavity. Check that its wire connector at the back of the range is firmly plugged in.

    Unplug the range first. The sensor connector is accessible from the back panel.

    Tools required
  2. 2

    Test sensor resistance

    At room temperature, the sensor should read approximately 1,080-1,100 ohms with a multimeter.

    An open circuit (infinite ohms) confirms a failed sensor.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • Sensor reads open circuit at room temperature
  • Wiring shows heat damage or melted insulation
  • Connector pins are corroded or bent
