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 F4 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 return shortly after startup or during the affected cycle stage.
Fans or heating/cooling loads may cycle abnormally.
The appliance may run longer than expected.
Other components may be disabled because the control cannot trust the sensor input.
Why it happens
Possible causes
A fan, heater, compressor-related, or relay/control problem depending on the appliance.
An open, shorted, corroded, or loose sensor connection.
A blocked vent or prolonged door-opening condition.
Wiring damage between the sensor and the main control.
A temperature sensor reporting an implausible value.
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.
Allow for recovery after a large warm load or long door opening before judging a one-time temperature event.
Confirm doors/lids close fully and that user-accessible vents are not blocked.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
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.
