Hood fan runs but extraction is weak
Possible causes. Grease-loaded filters, an obstructed duct, a stuck exterior damper or a worn blower can reduce airflow. A recirculating hood filters air rather than exhausting outdoors.
What the technician checks. The technician identifies the hood configuration, checks permitted filter access and observes blower operation. Duct routing and termination may require a separate building or ventilation assessment.
Typical repair. A suitable filter, blower component, switch or control may be replaced after diagnosis. Structural duct changes are not assumed to be part of appliance repair.
First-visit outlook. The model, safe access and required parts determine the visit scope. We explain the findings and quote before work; completion on the first visit is not guaranteed.
