Safety: Use caution when working in a hot oven.

Verify with thermometer: Place an oven thermometer in the center of the oven and run at 350°F for 20–30 minutes. Compare average reading to set temperature.
Adjust calibration: Many GE models allow temperature adjustment in the settings menu (e.g., +/- 35°F). Follow the user manual to calibrate.
Check door seal: Inspect the door gasket for gaps, tears, or compression. Replace if damaged.
Sensor replacement: If calibration cannot correct large errors, replace the oven temperature sensor.

Oven temperature too hot or too cold compared to set temperature.
