Code F2 on GE oven displays points to a defective temperature sensor that disrupts proper oven operation. Replacing the sensor resolves the fault in most cases without needing professional service.
Checking the wiring for damage follows as the next step if the code returns after replacement. Owners should verify the new sensor resistance values match specifications before final assembly. This approach restores accurate temperature control during bake and broil cycles.

A quick reference helps isolate the F2 error on GE ovens before any disassembly begins. The table below matches common symptoms to likely causes and rates repair difficulty. Users review this data first to decide whether to proceed with a home fix or seek outside help. Accurate identification avoids wasted time on unrelated components like the control board.
| Symptom | Primary Suspect | Difficulty 1-5 |
|---|---|---|
| F2 code during preheat | Temperature sensor open circuit | 3 |
| Intermittent F2 after heating | Damaged sensor wiring | 2 |
| F2 with no heat at all | Failed sensor element | 4 |
GE Oven F2 Sensor Resistance Causes
The F2 code triggers when the control board detects resistance outside the normal range from the oven temperature sensor. This sensor sits inside the oven cavity and sends temperature data through a wiring harness. Corrosion or physical breaks in that harness produce the same error as a bad sensor itself. Heat cycles over years eventually degrade the sensor probe or loosen its connections.
GE Oven F2 Sensor Replacement Steps
Disconnect power at the breaker before starting any work on the oven. Remove the oven racks and unscrew the sensor mounting clip inside the cavity. Pull the sensor gently through the rear access panel while supporting the wiring. Install the new sensor by reversing the removal steps and secure all connections. Restore power and run a test cycle to confirm the code clears.
GE Oven F2 Sensor Resistance Readings
Technicians test the sensor with a multimeter set to ohms before ordering parts. Normal readings at room temperature fall between 1000 and 1100 ohms for most GE models. Higher or infinite readings confirm an open circuit that requires replacement. Lower readings often indicate a shorted sensor that will not regulate heat properly.
Users repeat the measurement at the control board connector to rule out wiring issues. Consistent values at both ends point directly to the sensor. Inconsistent values require harness inspection next.
GE F2 Oven Wiring Harness Checks
The wiring harness runs from the sensor through the oven back wall to the control board. Remove the rear panel screws to expose the harness route. Check each connector for corrosion or bent pins that interrupt the signal. Replace damaged sections of harness if visual inspection shows fraying or melted insulation.
This step prevents repeat F2 codes after a new sensor installation. Secure all plugs firmly before reassembling panels.
GE Oven F2 Sensor Calibration Adjustment
New sensors sometimes require a small offset adjustment through the control panel menu. Enter diagnostic mode per the model manual and compare displayed temperature to an external thermometer. Adjust the calibration setting if the difference exceeds 10 degrees. Run multiple cycles to confirm stable performance without error codes.
GE F2 Sensor Part Number Matching
When addressing an F2 error on a GE oven, matching the temperature sensor part number to the exact model prevents installation of incompatible components. Accurate selection restores sensor function and eliminates the fault without repeated disassembly. This step confirms the replacement aligns with factory specifications for reliable temperature control.
Order the correct GE sensor part number matched to the oven model from an authorized supplier. Keep the old sensor as a reference during installation.
