Jenn-Air Oven F3-E0 Error: Upper Sensor Open
What Does Jenn-Air Oven Error Code F3-E0 Mean? Error code F3-E0 on a Jenn-Air wall oven signals an open circuit in the upper oven temperature sensor. This sensor is a resistance temperature detector (RTD) probe mounted inside the oven cavity that the control board relies on to regulate cooking temperatures. Common Causes The sensor probe […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. The upper oven cannot regulate temperature without a working sensor. The lower oven (if equipped) may still work if it has a separate sensor.
Can I reset the code?
Yes. A reset clears the error display, but it will return as soon as the oven tries to heat.
When to stop immediately?
Stop if you notice: Oven refuses to heat at all, Temperature display is clearly inaccurate.
Symptoms You May Notice
Upper oven will not heat
The upper oven cavity does not produce heat when a bake or broil cycle is selected.
Heating cycle cancels after a few minutes
The oven starts heating but shuts down shortly after because it cannot verify temperature.
Display shows extreme temperature reading
The temperature display reads an unrealistic number — very high or stuck at zero.
Possible Causes
Failed RTD temperature sensor
The resistance temperature detector inside the upper oven has an internal break, creating an open circuit.
Requires ProfessionalDisconnected sensor wiring
The wire from the sensor to the control board has come unplugged or has a broken conductor.
DIY PossibleSafe Checks You Can Do
-
1
Check the sensor connector
Turn off the breaker. Locate the sensor probe at the top rear of the upper oven and check that its wire connector is firmly seated.
The connector is usually accessible through the back panel of the oven.
Tools required -
2
Measure sensor resistance
Disconnect the sensor and measure resistance with a multimeter. It should read about 1,080-1,100 ohms at room temperature.
An open circuit (OL on the meter) confirms a failed sensor.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Sensor resistance is open at room temperature
- Connector shows corrosion or heat damage
- Wiring insulation is melted or brittle
