Based on customer reports and repair data, this part commonly fixes these issues:
Many range vent hoods have a vent damper positioned above the blower motor to help keep the outside air from migrating back into the house when the vent is not in use. If the damper is damaged or obstructed it may be unable to open to allow the air to vent properly. Inspect the vent damper for an obstruction or damage and replace if necessary.
