Step 01
Signs
• Oven will not heat or maintain temperature
• Temperature display shows incorrect readings
• Oven cycles on and off unexpectedly
• Unable to complete baking or roasting functions
• Error code F33 appears on the control panel display
• Range may not respond to temperature adjustments
• Cooking times are significantly longer than normal
• Food cooks unevenly or remains undercooked
Step 02
Possible Causes
• Temperature sensor (RTD probe) is faulty or has failed
• Loose or disconnected wiring harness to the sensor
• Corroded or damaged sensor connector terminals
• Damaged sensor wire from normal wear or exposure to moisture
• Oven interior has excessive food debris blocking proper sensor operation
• Manufacturing defect in the sensor assembly
• Voltage fluctuations from 240V circuit affecting sensor signal
• Control board failure preventing sensor signal interpretation
Step 03
Safety Checks You Can Do
• Check your home's circuit breaker panel to ensure the 240V breaker for the range is in the ON position; reset if tripped
• Allow the range to cool completely for at least 30 minutes before proceeding
• Inspect the interior of the oven for any visible food debris, spills, or obstructions; gently clean with appropriate oven-safe materials if needed
• Verify the oven door closes completely and the latch engages properly
• Check that no cookware or racks are touching or blocking the temperature sensor probe
• Review the control panel settings to ensure correct temperature and cooking mode are selected
• Power cycle the range by turning off the 240V circuit breaker for 60 seconds, then switch it back ON
• If F33 clears, retry the oven function at a moderate temperature (350°F) to see if error recurs
• Do NOT attempt to remove or repair the temperature sensor yourself as this may void warranty and create safety hazards
