What Does Error F3 Mean?
The Admiral oven F3 error indicates a malfunctioning temperature sensor, causing erratic temperature readings and inconsistent cooking results. This error arises when the control board detects a shorted or open signal from the oven temperature sensor (RTD), leading to failure in heating or temperature regulation. Common symptoms include the F3 code display, inaccurate temperature, and fluctuating heat levels.
Common Symptoms:
- Oven displays F3 on control panel
- Oven fails to heat or regulates temperature incorrectly
- Temperature may be inaccurate or fluctuating
Possible Causes
- Open or shorted oven temperature sensor (RTD) (high)
- Loose, disconnected, or damaged wiring between sensor and control board (medium)
How to Fix Error F3
DIY Fix Initial checks for F3 error
- Disconnect the oven from power (turn off circuit breaker or unplug).
- Visually inspect the oven temperature sensor (inside oven cavity) and surrounding wiring for obvious damage.
- Ensure sensor is not touching the oven wall and that connectors are seated properly.
Technician Only Test and replace temperature sensor
- Disconnect power to oven.
- Access the temperature sensor and harness (typically inside oven cavity or rear panel).
- Use a multimeter to measure sensor resistance; compare to expected values per model service manual.
- If sensor is open or out of range, replace with correct RTD sensor for the oven model.
- Reassemble and restore power, verify error code is cleared.
Parts needed: oven temperature sensor (RTD), possibly wiring harness or connectors
- If error persists after sensor inspection and replacement
- If control board appears to have damage or other unrelated faults
