How to Fix / Troubleshooting
Safety first: Unplug the air fryer and allow it to cool fully before opening the housing.
Steps to address excessive exterior heat:
- 1. Confirm normal expectations: The exterior may become warm, but should not be too hot to touch briefly. If it is, continue.
- 2. Check ventilation clearance: Ensure proper spacing around the unit and that vents are not blocked.
- 3. Inspect internal heat shields: Remove the cover and look for metal shields around the heater and cooking chamber. Ensure they are intact and properly mounted.
- 4. Check insulation: Some models use insulation blankets or pads. Verify they are in place and not burned or missing.
- 5. Verify correct heater: If the heating element was previously replaced, confirm it matches the original Insignia wattage and design.
- 6. Replace damaged shields or insulation: Install OEM heat shields or insulation if any are missing or degraded.
Warning: Excessive exterior temperatures can be a burn hazard and may indicate internal overheating.
