Air fryer heats but cooking temperature is too low; food takes much longer than recipe times.

Safety first: Unplug and cool before touching internal parts.

• Verify settings: Confirm the correct temperature and time are selected and that preheating is allowed when required.
• Check door/lid seal: Inspect the silicone or rubber gasket around the lid for gaps, tears, or hardened sections. Replace if damaged.
• Avoid overloading: Do not overfill the basket; thick layers of food reduce effective temperature.
• Test with thermometer: Use an oven-safe thermometer in the basket to compare actual temperature to the set value. If significantly lower, the sensor or control board may need replacement.

Warning: Internal calibration is not user-adjustable on most Panasonic models; component replacement is usually required.
