Temperature is inaccurate; food undercooks or overcooks compared to the set temperature.

Safety first: Unplug the fryer and allow it to cool before accessing internal components.

• Verify with thermometer: Use an oven-safe thermometer placed in the center of the cavity. Run the fryer at a known temperature and compare the reading after preheat.
• Clean sensor area: Locate the temperature sensor inside the cavity (small metal probe). Clean any grease or debris around it to ensure accurate sensing.
• Inspect sensor mounting: From the rear, verify that the sensor is firmly mounted and not pulled away from the cavity wall.
• Replace sensor if drifted: If readings are consistently off by a large margin (e.g., 50°F or more), replace the temperature sensor (NTC probe).
• Control board replacement: If a new sensor does not correct the issue, the control board’s regulation circuit may be faulty. Replace the main control board.
