Step 01
Signs
• Oven will not heat or heat inconsistently
• Temperature display shows incorrect readings
• Oven shuts off during cooking cycles
• Error code F1 appears on the control panel display
• Unable to preheat oven to desired temperature
• Range may not respond to temperature adjustments made via control panel
• Stovetop burners may work normally while oven is non-functional
Step 02
Possible Causes
• Faulty or damaged oven temperature sensor (RTD sensor)
• Loose or disconnected wiring harness connected to the temperature sensor
• Corroded or damaged sensor connector pins
• Sensor wire short circuit or open circuit condition
• Control board malfunction unable to read sensor signals
• Manufacturing defect in the sensor resistance element
• Thermal damage to sensor from prolonged high-heat exposure
• Moisture or debris contamination in sensor connector
Step 03
Safety Checks You Can Do
• Power reset: Turn off the circuit breaker supplying power to the range for 60 seconds, then turn it back on to clear temporary error codes
• Verify circuit breaker: Check that the 240V double-pole circuit breaker for your range is in the ON position and has not tripped
• Inspect oven interior: Ensure the oven interior is clean and free of food debris, spills, or racks that could obstruct heat circulation
• Check oven door: Confirm the oven door closes completely and latches properly, as a loose door can trigger sensor errors
• Review control panel settings: Verify all settings are correct and the range is not in a lock or demo mode that would prevent oven operation
• Allow cooling time: Wait at least 15-20 minutes for the range to cool completely before attempting to use it again
• Test stovetop functions: Confirm cooktop burners operate normally to isolate whether the issue is oven-specific
• Examine visible wiring: If safely accessible, look for any visibly loose connections or damaged wires near the sensor area (do not force any components)
• Power cycle multiple times: Try turning the breaker off and on several times in succession, as intermittent connection issues may clear temporarily
