What Does Error F4 Mean?
The Admiral oven F4 error code indicates a malfunction in the oven temperature sensor (thermistor). This issue leads to erratic temperature readings, causing the oven to stop heating or fail to maintain consistent cooking temperatures. The fault may be due to a shorted or open circuit in the temperature sensor, which is crucial for accurate temperature regulation during cooking cycles.
Common Symptoms:
- Oven stops heating or will not maintain temperature
- Error appears during oven operation or when temperature sensing is active
Possible Causes
- Oven temperature sensor short or open circuit (medium)
How to Fix Error F4
DIY Fix Power cycle and basic checks
- Disconnect the oven from power for at least one minute.
- Reconnect power and observe if F4 reappears during a cooking cycle.
Technician Only Test and replace oven temperature sensor
- Disconnect power to the oven.
- Access the oven temperature sensor (thermistor) inside the oven cavity.
- Disconnect the sensor at its connector and measure its resistance with an ohmmeter.
- If resistance is open or out of normal range for the model, replace the sensor.
- Inspect and repair any damaged wiring or connectors between the sensor and oven control.
- Restore power and verify the F4 code does not return.
Parts needed: oven temperature sensor (thermistor), wiring harness/connector
- If error persists after sensor replacement and wiring inspection
- If control board diagnostics indicate underlying control electronics failure
- If any diagnostics require specialized tools or internal access that could risk safety
