How do I clean the condenser, and when is it necessary?

There is no need for routine condenser cleaning in normal home operating environments. However, if the environment is particularly greasy, dusty, or has significant pet traffic, the condenser should be cleaned every 2 to 3 months. To clean it, remove the base grille and use a vacuum cleaner with a soft brush to clean the grille, open areas behind the grille, and the front surface of the condenser, then replace the base grille.
