Why the control reported this error
GE groups F3 and F4 around the oven temperature sensor. Depending on the model and failure state, the sensor circuit may be open, shorted, disconnected, or reporting an implausible value; wiring and the control input should be checked before a sensor is replaced.
Possible causes
Check the most likely causes first
- 1
open, shorted, or failed oven temperature sensor
Start here when it matches your symptoms.
- 2
sensor harness or connector fault
- 3
electronic control sensor-input fault
Diagnostic sequence
Work through these checks in order
Stop when you find the fault. Do not perform a step that requires skills or live testing you are not qualified to do.
- 1
Check 1
Turn the oven or range off and record the code.
- 2
Check 2
Disconnect power for at least 60 seconds, then restore power once.
- 3
Check 3
If the code returns, stop repeated resets and diagnose the listed circuit using the model service information.

Common questions
Quick answers for this fault
What should I check first for F3?
Start with open, shorted, or failed oven temperature sensor. If that checks out, continue through the diagnostic sequence above rather than replacing a part based on the code alone.
Does F3 always mean Oven Temperature Sensor is bad?
No. An error code identifies the condition the control detected, not a guaranteed failed part. Confirm the likely causes and wiring first. The exact OEM part number varies by model and production revision. Verify the complete model number before ordering.
When should I stop troubleshooting F3 myself?
Stop if the next step requires live electrical testing, sealed-system work, gas or combustion service, or any procedure outside your training. Turn the appliance off before internal service. Cooking appliances can contain 120/240-volt circuits, high-temperature surfaces, and on gas models combustible fuel; qualified service is recommended for internal electrical or gas work.

Bad Line appears when the range or oven detects incorrect electrical wiring at the power connection.
GE documents F0, F1, F6, and F7 as keypanel-related faults on applicable ranges and wall ovens.
F2 or F20 indicates that oven temperature exceeded a preset safety threshold.
Code F30 indicates the electronic control board senses an open circuit (infinite resistance) in the oven sensor circuit.
