How do I clean the condenser and how often is it needed?

In normal home environments, routine condenser cleaning is not necessary. 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, the open areas behind it, and the front surface of the condenser.
