Step 01
Signs
• Oven will not heat or begin cooking cycles
• Display shows F0 error code continuously
• Oven beeps repeatedly and locks out user controls
• Unable to set temperature or select cooking modes
• Oven may appear completely unresponsive to button presses
• Interior light may still function while heating functions remain disabled
• Error code may appear shortly after power is applied or during mid-cycle cooking
Step 02
Possible Causes
• Loose or disconnected wiring harness between control board and temperature sensor
• Faulty oven temperature sensor (RTD or thermistor) unable to communicate readings
• Damaged or malfunctioning electronic control board
• Power supply voltage fluctuations affecting 240V or 120V circuit delivery
• Failed relay or contactor preventing proper signal transmission
• Corroded electrical connections due to moisture or normal wear in North American kitchens
• Software glitch or corrupted control board programming requiring reset
• Door latch switch malfunction preventing proper oven closure detection
Step 03
Safety Checks You Can Do
• Verify the circuit breaker dedicated to your oven has not tripped; check your electrical panel and reset if necessary
• Allow the oven to cool completely for at least 30 minutes before attempting any troubleshooting
• Inspect the oven door to ensure it closes fully and latches properly with no visible gaps
• Check that the oven interior is clear of any food debris, racks, or obstructions that may interfere with sensors
• Review your oven's control panel to confirm no settings are locked or in a special mode
• Perform a complete power reset: turn off the breaker serving the oven for 60 seconds, then switch it back on and wait 5 minutes for the control board to reinitialize
• Attempt to run a simple test cycle (preheat to 350°F) to see if the error clears after reset
• Verify that your home's electrical service is delivering proper voltage and that no other appliances are causing power fluctuations
• If the error persists after these steps, contact a certified GE service technician as internal component replacement may be required
