How do I clean the condenser, and how often should it be done?

In normal home environments, there is no need for routine condenser cleaning. 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, unplug the refrigerator, 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.
