Step 01
Signs
• Oven will not heat or heats inconsistently
• Temperature display shows incorrect readings
• Oven may cycle on and off repeatedly
• Unable to preheat oven to desired temperature
• Error code F32 displays on the control panel
• Cooking results are uneven or food is undercooked
• Range may lock out and prevent cooking functions
Step 02
Possible Causes
• Temperature sensor (thermistor) is faulty or defective
• Loose or disconnected wiring harness to the temperature sensor
• Corroded or damaged sensor connections
• Temperature sensor is physically damaged or broken
• Control board failure affecting sensor signal reception
• Buildup of debris around the sensor probe in the oven cavity
• Electrical connection issue between sensor and main control board
• Sensor resistance values out of acceptable range (common in 240V USA models)
Step 03
Safety Checks You Can Do
• Turn off power to the range by switching off the circuit breaker for at least 60 seconds, then turn it back on to reset the appliance
• Verify the circuit breaker serving the range (typically 40-50 amp double-pole breaker for 240V models) is in the ON position and has not tripped
• Allow the range 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 visible debris, food buildup, or obstructions around the oven walls
• Ensure the oven door closes fully and latches properly with no gaps
• Check that all control panel buttons and knobs are functioning normally and responding to input
• Review the range's user manual to confirm correct temperature settings and cooking mode selection
• Attempt to manually set the oven to a low temperature (such as 200°F) and listen for heating element activation
• If error persists after these checks, contact a certified GE appliance repair technician or call GE Customer Service for further diagnostics
