Temperature seems inaccurate; food is undercooked or overcooked compared to the set temperature.

Safety first: Use an oven-safe thermometer to test temperature; avoid touching hot surfaces.

Steps to correct temperature inaccuracy:

• 1. Verify with thermometer: Place an oven thermometer in the basket, set the air fryer to a known temperature (e.g., 180°C/356°F), and compare readings after preheat.
• 2. Clean interior: Remove grease and debris from the heater area and fan guard to restore proper airflow.
• 3. Inspect sensor placement: Access the temperature sensor near the heater. Ensure it is firmly attached and positioned in the airflow, not touching the heater directly.
• 4. Replace sensor: If readings are consistently off by a large margin, replace the NTC temperature sensor with a Proscenic-compatible part.
• 5. Replace main PCB if needed: If a new sensor does not correct the issue, the control algorithm or ADC on the main PCB may be faulty; replace the board.
• 6. Adjust usage: Until repaired, you may compensate by adjusting set temperatures, but this is not a permanent fix.

Warning: Incorrect temperature can pose food safety risks; ensure meats reach safe internal temperatures.
