Whirlpool Range F3E1 Error: Oven temp sensor open circuit
If you are dealing with a whirlpool range f3e1 error, this guide will help you understand the cause and find the right solution quickly. What Does the F3E1 Code Mean on a Whirlpool Range? F3E1 indicates the oven temperature sensor (also called an RTD or resistance temperature detector) is reporting an open circuit to the […]

Answer to continue safely
Is it safe to keep using?
No. Without a working temperature sensor the control board cannot regulate oven heat safely. Using the oven risks overheating and potential fire.
Can I reset the code?
Yes. F3E1 reflects a real hardware fault — a broken sensor or disconnected wire. A power reset will not fix the underlying problem; the sensor or wiring must be repaired.
When to stop immediately?
Stop if you notice: The oven begins heating but the temperature reading stays at maximum or shows dashes., You smell burning or see smoke from inside the oven cavity when attempting to cook..
Symptoms You May Notice
Oven produces no heat at all
The oven cavity remains at room temperature even after a long preheat period, indicating the heating element is not receiving power.
Preheat indicator never turns off
The "preheating" indicator stays on indefinitely because the control board cannot confirm the target temperature via the sensor.
Baking results inconsistent
Food comes out undercooked in some batches and overcooked in others because the oven temperature is uncontrolled.
Temperature fluctuating wildly
A separate oven thermometer shows the internal temperature swinging by 50 °F or more above and below the set point.
Possible Causes
Failed oven temperature sensor probe
The RTD probe element inside the sensor has broken, producing an open circuit that the control board interprets as an infinite temperature reading.
DIY PossibleBurned or broken sensor wiring
The two-wire harness running from the sensor to the ERC board passes through areas exposed to heat. A broken wire — often near the connector — causes an open-circuit fault.
DIY PossibleLoose sensor connector at the control board
The push-on connector at the ERC board can loosen after the range is moved or serviced, breaking the sensor circuit without damaging any components.
DIY PossibleSafe Checks You Can Do
-
1
Check and reseat the sensor connector
Unplug the range. Locate the oven temperature sensor on the upper rear wall of the oven cavity (two screws hold it in place). Disconnect and firmly reseat its wiring connector. Restore power and check if F3E1 clears.
Inspect the connector pins for any signs of corrosion or heat discoloration — darkened pins indicate arcing and the connector should be replaced.

Test sensor resistance with a multimeter
With the range unplugged, remove the sensor's two mounting screws and disconnect the wiring connector. Set a multimeter to ohms and measure across the two sensor terminals. A reading of 1,080–1,100 ohms at room temperature is normal. An "OL" or infinite reading means the sensor is open and must be replaced.
Sensor part numbers for WFG and WFE series are often printed on a label on the sensor body — photograph it before ordering a replacement.
Tools required
When to Call a Professional
Contact a qualified technician if:
- The sensor tests open (OL on multimeter) — it needs replacement, which most homeowners can do, but call a technician if you are uncomfortable with appliance disassembly.
- After replacing the sensor F3E1 persists — the wiring harness between the sensor and the ERC board has a break that requires professional tracing.
