Description
The Jandy Air Pressure Switch R0456400 is an authentic OEM safety device designed for Jandy JXI and LXI pool and spa heaters. This precision switch continuously verifies that adequate airflow exists inside the combustion chamber before allowing the heater to fire. When airflow drops below the minimum safe level, it immediately signals the control board to halt ignition, protecting the unit from unsafe operating conditions. Constructed with resilient, heat-tolerant materials, this switch is a cornerstone of your heater’s safety architecture and long-term operational reliability.
