Beyond cleaning the lint trap between each use, the dryer is a simple appliance when it comes to general maintenance. This once-yearly action is easy and will prevent clogs and keep your efficiency high.
Once a year, pull out the dryer and clean inside the dryer housing as well as cleaning through the dryer vent pipe with a brush or pipe cleaner.
Cleaning the filter housing every month for excess lint with a vacuum hose is recommended as well.
