Possible Causes

Clogged or dirty grease filters

How to Identify: Visible build‑up of oil/grease on filters; reduced airflow when holding a tissue near intake

Part: Grease or mesh filters

Accumulated grease/dirt on fan/blower

How to Identify: Diminished suction despite clean filters; greasy buildup on fan blades upon inspection

Part: Fan/blower assembly

Insufficient makeup air in room

How to Identify: Poor airflow only when room is tightly sealed; slight improvement when window/door is opened

Part: Kitchen ventilation environment (air supply)

Ductwork blockage or restriction

How to Identify: Weak suction even with filters and fan cleaned; debris visible at duct exit; tissue test shows minimal pull

Part: Duct/vent pathway

Fan motor/fan assembly wear or failure

How to Identify: No unusual blockage detected but airflow remains weak; motor noise abnormal or reduced speed

Part: Fan motor or blower
