Step 01
Signs
• Oven will not heat or maintain temperature
• Error code F14 displays on the control panel
• Oven beeps repeatedly or continuously
• Display shows "F14" followed by a number (such as F14-1 or F14-2)
• Inability to preheat the oven
• Cooking cycle stops unexpectedly
• Control panel may become unresponsive
• Oven door locks and will not unlock
Step 02
Possible Causes
• Temperature sensor (RTD probe) has failed or is defective
• Loose or corroded wire connections between the sensor and control board
• Damaged wiring harness leading to the temperature sensor
• Control board failure preventing proper sensor signal reading
• Sensor disconnected during previous maintenance or repair
• Moisture or corrosion in sensor connectors
• Manufacturing defect in the temperature sensing circuit
• Power surge damage to sensor electronics (120V/240V related)
Step 03
Safety Checks You Can Do
• Turn off the circuit breaker supplying power to the oven for 60 seconds, then switch it back on to perform a hard reset
• Verify the oven's circuit breaker has not tripped; check your electrical panel and reset if necessary
• Ensure the oven door is fully closed and latched properly
• Allow the oven to cool completely for at least 30 minutes before attempting to use it again
• Open the oven door and visually inspect the interior for any obvious obstructions, debris, or damage blocking the sensor area
• Check that no foil, racks, or food particles are touching the temperature sensor (typically a metal probe on the interior wall)
• Press the oven's reset button or clear error button on the control panel if available
• Attempt to manually set a cooking temperature and initiate a preheat cycle to see if the error clears
• Consult your user manual to confirm F14 error code definition for your specific model
• If the error persists after these steps, contact a GE-authorized service technician as sensor replacement typically requires professional repair
