AquaCal STK0073 Fan Pressure Switch

The AquaCal STK0073 Fan Pressure Switch is a genuine OEM safety and airflow monitoring switch designed to verify proper fan operation in compatible AquaCal pool heat pumps. This switch confirms adequate airflow across the heat exchanger before allowing the system to operate, helping protect internal components and ensure safe, efficient heating. When a fan pressure switch fails, heat pumps may display fault codes, shut down unexpectedly, or refuse to start. Replacing it with the STK0073 restores proper safety monitoring and reliable system operation.

Airflow verification is critical to heat pump performance and longevity. The fan pressure switch ensures the fan is moving sufficient air to prevent overheating and system stress. Installing a factory-spec replacement helps resolve airflow-related faults, improves operational reliability, and supports consistent pool heating performance.
