The Hayward IDXLVPS1930 Vent Pressure Switch is a genuine OEM safety component engineered for use in compatible Hayward pool and spa heaters. This switch monitors the vent pressure or draft in the heater’s exhaust system to ensure that combustion gases are being properly expelled before the burner fires. Proper draft is crucial for safe and efficient operation—without it, combustion by‑products can remain trapped in the system, potentially causing malfunctions or unsafe conditions.
When vent pressure is within acceptable limits, the switch signals the control board that it’s safe to proceed with ignition. If acceptable draft is not detected—due to blocked venting, poor airflow, or system issues—the vent pressure switch prevents firing to protect internal components and maintain safety.
