What Does Error F3 Mean?
The Roper oven F3 error code signifies a malfunctioning temperature sensor circuit, which may cause erratic temperature readings or prevent the oven from heating properly. This issue is typically due to an open or faulted temperature sensor (RTD) circuit detected by the control board. Immediate symptoms include the F3 code displayed on the control panel, failure to heat, and the error appearing right after power-up or when starting a cooking cycle.
Common Symptoms:
- F3 displayed on oven control panel
- Oven fails to heat or begin cooking cycle
- Error appears immediately upon power-up or when starting operation
Possible Causes
- Open oven temperature sensor (RTD) circuit or failed sensor (high)
- Faulty wiring or connection to the temperature sensor (medium)
How to Fix Error F3
DIY Fix Basic diagnosis and reset
- Disconnect power by unplugging the oven or turning off its breaker.
- Wait a few minutes and restore power to see if the F3 code clears.
- Observe whether the error returns immediately when starting a cooking cycle.
Technician Only Inspect and test oven temperature sensor circuit
- Disconnect power to the oven.
- Access the oven cavity rear to locate and remove the temperature sensor (RTD).
- Use a multimeter to measure sensor resistance; typical RTD sensors should read around ~1100 ohms at room temperature.
- Inspect wiring harness and connectors for continuity and secure connections.
- Replace the temperature sensor if readings are out of expected range or if wiring is compromised.
- Reassemble and test the oven to verify that the F3 code no longer appears.
Parts needed: Oven temperature sensor (RTD), Wiring harness/connectors (if needed)
- If after replacing or verifying the temperature sensor and wiring the F3 error persists, indicating a potential control board fault
- If you are uncomfortable or inexperienced working with electrical components inside the oven
