GE Oven F03 Error Code
Open oven temperature sensor
What this error means
F03 means oven temperature sensor circuit is open.
How F03 is detected
Temperature and pressure sensors on GE oven models provide feedback loops the control uses to modulate heat, defrost, and cycle timing. F03 indicates the sensor circuit read open, shorted, or out of range. On GE JGB735SPSS, GE PTS9200SNSS, and similar variants, wiring harness damage at hot connectors, corrosion from steam, or the sensor element itself fails most often.
breaker off. Reseat connectors before replacing sensors—RTD oven probes should read approximately 1,080 ohms at room temperature on many GE and Whirlpool platforms. Compare your reading to the service chart for GE JGB735SPSS, GE PTS9200SNSS, and similar variants. Intermittent F03 during high heat often traces to wire routing touching hot internal surfaces.
If F03 persists after the steps above on GE JGB735SPSS, GE PTS9200SNSS, and similar variants, request service with the exact cycle phase noted (fill, wash, drain, heat, or cool-down) and whether the fault clears after a breaker reset. GE warranty and extended service plans may cover control boards and sealed-system work depending on age and installation date.
Common causes
- Loose plug
- Broken wire
- Failed RTD
- Corrosion

When to call a technician
New probe with F03 needs ERC wiring.
Affected models
- GE JGB735SPSS
- GE PTS9200SNSS
- GE JB735SPSS
Prevention & maintenance
- Avoid steam cleaners directly on control panels; moisture ingress causes sensor and keypad faults including F03.
- Record when F03 appears in the cycle and whether it clears after a 60-second power reset on your GE oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F03; GE 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.
