Thoroughly clean the dryer every year. Have an authorized service representative perform this maintenance.
Clean the lint filter before drying each load. The lint filter may be washed if needed. Annually remove lint filter and screw to vacuum the duct under it.
Inspect the exhaust duct for lint build-up after one year of service. Clean if necessary. Inspect every one to two years as required thereafter.
Inspect the outside weather hood frequently to make sure dampers move freely, dampers are not pushed in and that nothing has been set against them.
