Kenmore Range Error Code F3-E0

Break in oven sensor circuit

Kenmore codesKenmore range codes

Break in oven sensor circuit — Open sensor, loose or disconnected sensor connector at sensor or control, or open wire in harness.

First step from the service manual

1. Verify failure if not displayed. Go to manual diagnostics screen 5 to view and clear error codes. 2. Use manual diagnostics screen 2 to view the status screen. 3. Check temperature reading; should read approximately room temperature. 4. Disconnect sensor and measure resistance between connector pins (1000 ohms at 32°F to 2697 ohms at 900°F, approx. 1080 ohms at room temp). 5. If measurement incorrect, replace sensor. 6. Trace wires and connectors; replace harness if damaged. 7. If failure remains, replace the control.

What F3-E0 means on a Kenmore range

The F3-E0 error code on a Kenmore range indicates an open circuit condition in the oven temperature sensor system. The oven sensor, also called a resistance temperature detector (RTD), is a probe mounted inside the oven cavity that changes its electrical resistance in proportion to temperature. The electronic control board continuously monitors this resistance to regulate oven temperature. When the control detects an open circuit rather than a valid resistance signal, it sets the F3-E0 code and typically disables the bake and broil functions to prevent unsafe operation.

The open circuit can originate at three points: the sensor probe itself, the wiring harness running from the sensor to the control board, or the connectors at either end of that harness. A properly functioning oven sensor should measure approximately 1080 ohms at room temperature, rising to roughly 2697 ohms at 900 degrees Fahrenheit, and dropping to around 1000 ohms at 32 degrees Fahrenheit. Any reading significantly outside this range, or a completely open reading with no continuity, points to a failed sensor. A reading of infinite resistance (OL on a multimeter) when the sensor is disconnected confirms the probe element has broken internally.

Diagnosis follows a structured path: first confirm the code using manual diagnostics screen 5, then check the live temperature reading on diagnostics screen 2. If the display shows an unrealistic temperature or an error in place of a temperature value, proceed to disconnect the sensor connector and measure resistance directly across the sensor pins. If resistance is correct, the fault lies in the wiring harness or connectors between the sensor and the control board. If wiring checks out and the fault persists after sensor replacement, the control board itself may have a failed input circuit.

Common causes of F3-E0

  1. 01

    Failed oven temperature sensor

    Part replacement

    The RTD probe inside the oven cavity can fail internally, breaking the electrical circuit entirely. Disconnecting the sensor and measuring resistance across its pins will confirm failure if the reading is open (infinite resistance) or well outside the expected range of approximately 1080 ohms at room temperature.

  2. 02

    Loose or disconnected sensor connector

    Wiring / connection

    The connector at the back of the sensor probe or at the control board can work loose over time due to heat cycling and vibration. Visually inspect both connector ends and reseat them firmly before replacing any parts.

  3. 03

    Damaged wiring harness

    Part replacement

    The wires running between the sensor and the control board can chafe against metal edges, burn from oven heat, or develop breaks from repeated flexing. Trace the full length of the harness and look for visible damage, scorching, or pinched sections.

  4. 04

    Broken wire at a terminal

    Wiring / connection

    Individual wires can break internally at a crimp terminal while the insulation looks intact, making the fault invisible to a visual inspection. Use a multimeter to check continuity along each wire in the sensor circuit.

  5. 05

    Failed electronic control board

    Part replacement

    If the sensor measures correctly and the wiring and connectors are intact, the sensor input circuit on the control board may have failed. This is the least common cause and should only be suspected after all other components have been confirmed good.

Frequently asked questions about F3-E0

What does F3-E0 mean on a Kenmore range?
F3-E0 indicates an open circuit in the oven temperature sensor system. The control board is not receiving a valid resistance signal from the oven sensor, which it needs to regulate baking and broiling temperatures. The fault can be located at the sensor probe itself, the wiring harness, or the connectors linking those components to the control board.
Can I reset the F3-E0 code by unplugging the range?
Cycling power may temporarily clear the code, but it will return as soon as the control board attempts to read the sensor again and finds the circuit still open. A proper fix requires identifying and correcting the underlying fault, whether that is a bad sensor, a loose connector, or a damaged wire. Use manual diagnostics screen 5 to view and clear stored codes after the repair is complete.
Is it safe to use my Kenmore range while F3-E0 is displayed?
It is not advisable to use the oven while this code is active. Because the control board cannot monitor oven temperature, it has no way to regulate the heating elements accurately, which creates a risk of overheating. Surface burners on a gas or electric range may still function, but the oven should remain off until the sensor circuit is repaired.
How do I fix the F3-E0 error on a Kenmore range?
Start by checking the sensor connector at the back wall of the oven cavity and reseating it firmly. Then disconnect the sensor and measure its resistance with a multimeter; it should read close to 1080 ohms at room temperature. If the resistance is open or incorrect, replace the sensor. If the sensor reads correctly, inspect the wiring harness for damage and replace it if needed. If the fault persists after addressing the sensor and wiring, the control board may need replacement.
How much does it cost to repair a Kenmore range F3-E0 error?
Repair costs vary depending on which component has failed. An oven temperature sensor typically costs between 20 and 60 dollars for the part, and professional labor to install it can add 75 to 150 dollars depending on your area. A replacement wiring harness generally falls in a similar parts price range. A new control board is the most expensive scenario, with parts often ranging from 100 to 300 dollars or more depending on the model.
