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.
