Product details

Hayward IDXLVPS1930 is the genuine OEM vent pressure switch for H-Series pool heaters.

What it does

The vent pressure switch is a safety interlock. Before the heater is allowed to light, the switch has to see that the venting is doing its job. If it does not, the control locks the heater out. That is deliberate: a gas appliance that fires without proving its venting is a hazard.

Diagnosing it

A failed switch reads as a heater that runs its start sequence and then refuses to fire. Before replacing the switch, rule out a blocked or restricted vent, a failing blower, and a wiring or connector fault, because all of them look the same from the front panel. If the venting is clear and the switch never closes, the switch is the part.

Never jumper a vent pressure switch to get the heater running. It removes a combustion safety and leaves the underlying fault in place.

Questions and answers

What people ask about this product, answered by our pool techs.

What does the vent pressure switch do?
It confirms the heater is venting properly before the burner is allowed to light. If it does not see the expected condition, the heater will not fire.
Is this the genuine Hayward part?
Yes. It is Hayward OEM part IDXLVPS1930.
My heater will not light. Could this be it?
It is a common cause, but not the only one. Blocked venting, a failing blower or a wiring fault can produce the same symptom, so diagnose before you replace.
Can I just jumper the switch?
No. It is a combustion safety device. Bypassing it may get heat for a day and removes the protection the heater depends on.
