The Hayward IDXL2VPS1930 Vent Pressure Switch is a genuine OEM safety control component designed for use in compatible Hayward pool and spa heaters. This switch monitors the vent pressure (draft) in the heater’s exhaust system to ensure that combustion gases are being properly evacuated before allowing the burner to fire.
Proper vent pressure is essential for safe operation: if the vent path is blocked or draft is insufficient, the heater may not safely expel combustion by-products, which could risk equipment damage or unsafe conditions. The vent pressure switch helps prevent ignition under these unsafe conditions by signaling the heater control to inhibit firing until acceptable vent pressure is detected.
