When the defrost cycle is terminated, what happens to the evaporator fans?

When the defrost cycle is terminated, the evaporator fans typically experience a brief delay before being energized. This delay is intentional and serves a crucial purpose: it ensures that any residual moisture from the defrosting process is allowed to drain away properly before the fans are activated. Starting the fans too soon could lead to reintroducing moisture into the air within the refrigerated space, potentially causing ice to form on the evaporator coils again or affecting the temperature balance in the unit.

By ensuring a delay before the fans turn back on, the system helps maintain proper operational efficiency and prevents moisture-related issues that could negatively affect the refrigeration process. This method is a common practice in refrigeration systems to protect the equipment and optimize performance.
