Jenn-Air Oven F3-E1 Error: Lower Sensor Short
What Does Jenn-Air Oven Error Code F3-E1 Mean? Error code F3-E1 on a Jenn-Air double wall oven indicates the lower oven temperature sensor has a short circuit. Instead of reading the correct resistance, the sensor returns a value that is too low, which the control board interprets as an excessively high temperature. Common Causes The […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A shorted sensor causes the control board to misjudge temperature, potentially underheating or overheating the oven. The upper oven may still be used if it has a separate sensor.
Can I reset the code?
Yes. A reset clears the error temporarily, but the shorted sensor will trigger it again during the next heating cycle.
When to stop immediately?
Stop if you notice: Lower oven does not heat at all, Temperature display reading is clearly wrong.
Symptoms You May Notice
Lower oven heats unevenly or not at all
The lower oven fails to reach the set temperature or heats inconsistently.
Display shows temperature much higher than actual
The control panel displays a temperature that is clearly too high compared to the real oven temperature.
Lower oven shuts off prematurely
The heating element turns off before the oven has actually reached the target temperature.
Possible Causes
Shorted sensor probe
The RTD sensor inside the lower oven has developed a short circuit, giving a low resistance reading.
Requires ProfessionalPinched or damaged sensor wiring
The sensor wire is touching a grounded metal surface, creating a short to ground.
Requires ProfessionalSafe Checks You Can Do
-
1
Check sensor wiring for pinch points
Turn off the breaker and inspect the sensor wire routing inside the lower oven for any spots where the wire touches metal surfaces.
Wires can get pinched by oven racks or the oven door hinge mechanism.
-
2
Measure sensor resistance
Disconnect the sensor and check resistance at room temperature — should be around 1,080-1,100 ohms.
A reading significantly below 1,000 ohms confirms a shorted sensor.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Sensor resistance is below 900 ohms at room temperature
- Wiring shows bare copper touching grounded metal
- Sensor probe is discolored or physically damaged
