About This Item
The Hayward Blower Vacuum Switch (FDXLBVS1930) is the OEM replacement blower vacuum switch for Hayward Universal H-Series gas heaters.
IMPORTANT: PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The blower vacuum switch monitors the pressure differential created by the heater's blower motor to confirm adequate airflow before and during ignition. When the switch detects insufficient vacuum — indicating a blower failure or airflow obstruction — it interrupts the ignition sequence to prevent unsafe heater operation.

Poolaroo Pro Tip
A blower vacuum switch that trips repeatedly after replacement typically points to a restricted flue, a failing blower motor, or a blocked intake — not a defective switch. Have a licensed technician inspect the venting and blower assembly before condemning the new part. Always confirm heater power is fully disconnected before servicing any switch or control component.
