Possible Causes
Missing or damaged internal heat shield, Degraded insulation around cooking cavity, Blocked ventilation, Operating too close to walls or cabinets
How to Fix / Troubleshooting
Safety first: Always allow adequate clearance around the air fryer and avoid touching metal surfaces during operation.
Steps to address excessive exterior heat:
- 1. Improve placement: Move the unit away from walls and overhead cabinets. Provide at least 5 inches (12 cm) clearance on all sides.
- 2. Check vents: Ensure all ventilation openings are clear.
- 3. Inspect heat shields: With housing removed, verify that internal heat shields and reflective panels are in place and not bent or missing.
- 4. Replace insulation: If insulation material around the cavity is burned or missing, replace it with high-temperature insulation specified for your Granitestone model.
