How to Fix It
1
Remove and clean the lint filter thoroughly; wash with warm soapy water if coated with residue from dryer sheets
2
Disconnect the exhaust vent duct from the back of the dryer and check for lint accumulation
3
Use a vent cleaning brush or leaf blower to clear the entire vent duct run from the dryer to the exterior vent hood
4
Inspect the exterior vent hood for obstructions and ensure the flap opens freely
5
Verify the total vent run length does not exceed 35 feet for 4-inch rigid duct, reducing by 5 feet per 90-degree elbow
