Possible Causes
Blocked grease filters, disconnected vent duct, obstructed exhaust outlet, fan running in recirculation mode unintentionally
How to Fix / Troubleshooting
Safety: Unplug before removing filters or accessing ductwork.
Steps:
- 1. Clean filters: Remove and clean any grease filters according to the Tower manual. Clogged filters restrict airflow.
- 2. Check vent settings: For models with convertible venting, ensure the vent is configured correctly (recirculating vs. external vent).
- 3. Inspect duct: For externally vented installations, inspect the duct for kinks, blockages, or disconnections.
