Display shows H1 or "HOT" and the unit refuses to start a new cycle immediately after finishing one.

Safety first: Do not attempt to force the unit to run while it indicates high temperature; internal parts are hot.

Steps to handle H1/HOT:

• Allow cooling time: Open the basket drawer slightly and let the unit sit powered off for 10–20 minutes to cool down naturally.
• Improve ventilation: Ensure the air fryer has adequate space around it and is not placed under low cabinets that trap heat.
• Clean vents and interior: Remove grease and dust from vents and the interior cavity. Grease buildup can retain heat and slow cooling.
• Sensor check: If H1 appears even when the unit is cold, inspect and test the NTC temperature sensor as described in the E1/E3 procedures. Replace if out of range.

Note: A brief H1/HOT indication immediately after cooking is normal behavior and not a fault unless it persists for an unusually long time.
