Microwave exhaust fan (over-the-range) does not remove steam or smoke effectively.

Safety first: Turn off power at the breaker before removing filters or accessing ductwork.

Step-by-step checks:

• 1. Clean filters: Remove metal or charcoal filters and clean or replace them according to the Paderno manual.
• 2. Check vent direction: Verify that the blower is oriented correctly for your installation (recirculating or external vent).
• 3. Inspect duct: Check for crushed, blocked, or disconnected vent ducts above the microwave.
• 4. Test fan speeds: If airflow is weak on all speeds, the fan motor may be failing and require replacement.
