Frigidaire Oven F03 Error Code
Open oven temperature sensor
What this error means
F03 means the oven temperature sensor circuit is open on Frigidaire ranges and wall ovens.
How F03 is detected
When F03 appears on a Frigidaire oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On Frigidaire FGEH3047VF, Frigidaire FPEH3077RF, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most F03 calls are resolved without parts: shut off breaker. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If F03 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Sensor plug loose
- Broken probe wire
- Failed RTD
- Connector corrosion
Step-by-step fixes
- 1Shut off breaker
- 2Reseat sensor harness behind range
- 3Measure ~1080 ohms at room temp
- 4Replace probe if open
When to call a technician
New probe with F03 needs ERC wiring check.
Affected models
- Frigidaire FGEH3047VF
- Frigidaire FPEH3077RF
- Frigidaire GCFE3067AF
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use ovens to prevent F03 from lint and food debris buildup.
- Record when F03 appears in the cycle and whether it clears after a 60-second power reset on your Frigidaire oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F03; Frigidaire uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F03; reversed plugs on pumps and valves cause immediate repeat faults.
