KitchenAid Oven Error Code F3-E1 — Oven Temperature Sensor Open Circuit
What this means
Error code F3-E1 indicates the oven temperature sensor (also called the RTD or resistance temperature detector) has an open circuit. The sensor is a probe mounted inside the oven cavity that measures temperature. When the circuit is open, the control board cannot read the oven temperature, preventing the oven from heating or regulating temperature properly.
Alternate codes: F3E1
Step-by-step fix
4 stepsPower cycle the oven
Turn off the circuit breaker for 1 minute, then restore power. Sometimes a temporary connection issue triggers this error.
If the error clears, monitor the oven during the next few uses for recurrence.
Access the temperature sensor
Open the oven door and locate the temperature sensor probe inside the oven cavity. It is typically at the top rear of the oven, secured by one or two screws.
The sensor looks like a thin metal rod or probe extending a few inches from the back wall.
Test the sensor resistance
Unplug the oven. Disconnect the sensor wires from the back of the oven (or at the control board). Measure resistance across the sensor terminals with a multimeter. A working sensor reads approximately 1,080 ohms at room temperature.
An OL (infinity) reading confirms an open circuit. A reading far from 1,080 ohms also indicates a bad sensor.
Replace the temperature sensor
Remove the mounting screws inside the oven, pull the old sensor out, feed the new sensor wire through the opening, and secure it with the screws.
This is one of the simplest oven repairs — the sensor is accessed from inside the oven cavity.
When to call a professional
If the new sensor still shows the error, the control board's sensor input circuit may be damaged. Professional diagnosis is recommended.
