Step 01
Signs
• Oven will not heat or maintains incorrect temperatures
• Error code F2 displays on the control panel
• Oven may shut off unexpectedly during cooking
• Unable to start baking or broiling functions
• Range may enter a lockout mode preventing operation
• Uneven cooking results when oven does operate
Step 02
Possible Causes
• Faulty or defective oven temperature sensor (thermistor)
• Loose or corroded electrical connections on the sensor or wiring harness
• Damaged sensor wiring or broken sensor probe
• Control board malfunction preventing proper sensor signal reading
• 240V supply issues at the wall outlet affecting sensor circuit
• Buildup of food debris or grease around sensor location blocking accurate readings
• Sensor reading outside normal operating range (typically 32°F to 500°F)
• Improper sensor installation or positioning within the oven cavity
Step 03
Safety Checks You Can Do
• Check that the range is receiving proper 240V power by verifying the breaker is in the ON position in your home's electrical panel
• Allow the range to cool completely for at least 2 hours before attempting troubleshooting
• Inspect the oven interior for any visible food debris, grease buildup, or obstructions and clean if necessary
• Verify the oven door closes fully and latches properly
• Check that all control panel settings are at their default positions
• Review your user manual to confirm you are using correct cooking modes and temperature settings
• Power reset the range by switching the circuit breaker OFF for exactly 60 seconds, then switch it back ON
• Wait 5 minutes for the range to complete its initialization cycle
• Attempt to preheat the oven to 350°F and monitor for 10 minutes to see if the error reoccurs
• If the error persists after these steps, contact a certified GE service technician as the sensor or control board likely requires professional replacement
