User Suggested Solutions

Clean or replace the filters. Remove the filters from the range hood, wash them with warm soapy water, and let them dry completely before reinstalling. If they are damaged, replace them with new filters.
Check ducting for obstructions. Inspect the ductwork for any blockages or kinks that could impede airflow. Clear any debris and ensure that the duct is properly installed and sealed.
Test the motor and electrical connections. Use a multimeter to check if the motor is receiving power. If the motor is faulty, it will need to be replaced. If electrical connections are loose, tighten them.
