Affected model seriesrange and wall-oven common-code family
Quick answer
Oven-temperature sensor fault.
Model compatibility: GE reuses codes across series and model years, so F3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Oven-temperature sensor fault.
Signs
Symptoms you may notice
The code may appear after the control fails to reach or maintain a temperature target.
Food/cabinet/cavity temperature may be outside the set range.
The appliance may run longer than expected.
Temperature-related performance can become inconsistent.
Why it happens
Possible causes
A control fault that mismanages temperature after the physical system is checked.
A temperature sensor reporting an implausible value.
Wiring damage between the sensor and the main control.
A blocked vent or prolonged door-opening condition.
An open, shorted, corroded, or loose sensor connection.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Power the appliance off once and allow it to restart normally if there is no leak, overheating, or electrical damage.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
Confirm doors/lids close fully and that user-accessible vents are not blocked.
Do not disconnect internal sensors just to “test” whether the code clears; that can create additional faults.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
