None Range Hood: seeking effective ventilation

Professional Repair Guide

What is this symptom?

Is your range hood running but failing to provide effective ventilation? If smoke, odors, or steam linger during cooking, the issue may lie in clogged filters, internal grease buildup, or obstructed ducting. Addressing these common causes can significantly improve your kitchen's air quality.

Urgency: Medium

Possible Causes

Clogged or heavily soiled filters

How to Identify: Visible grease build‑up on filters and noticeably reduced airflow; air flow test with tissue shows weak suction.

Part: Filters (mesh/charcoal)

Fan (blower) and internal grease build‑up

How to Identify: Fan blades coated with grease; persistent poor suction after filter cleaning.

Part: Fan blades and internal housing

Obstructed or inefficient ducting

How to Identify: Long, bent, blocked or collapsed ducting; exterior vent cap clogged.

Part: Duct/vent pipe

Insufficient make‑up air (room air supply)

How to Identify: House extremely airtight; opening window improves hood performance.

Part: Room ventilation/makeup air

Damaged or sticky damper/vent flap

How to Identify: Vent flap doesn’t open when hood runs; external inspection shows blockage.

Part: Exterior damper/vent flap
