Product details

The Hayward CHXTSW1931 is the three way toggle system switch used on the H-Series heater control panel. It is the genuine Hayward part.

What it controls

The system switch is the selector on the front of the heater that sets which mode the unit runs in. Every call for heat passes through it, so when the contacts inside wear, the symptoms look like a much bigger fault: the heater does not fire, or it fires only sometimes, or it ignores the position you have set it to.

Check the switch before the board

Toggle switches are mechanical and they wear out. A switch that feels sloppy in the hand, or that has to be held to keep the heater running, has failed even if it looks fine. Testing continuity across the terminals in each of the three positions settles it in a couple of minutes and often saves a control board that was never the problem.

Fitment

Hayward lists CHXTSW1931 under H-Series heater parts and under the CZ 150 through 400 heater range. Isolate power at the breaker before opening the heater panel.

Questions and answers

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

What does the system switch do?
It is the three position selector on the heater panel that sets which mode the heater operates in. If it fails, the heater may not fire at all or may not respond when you change position.
Which heaters does it fit?
Hayward lists it under the H-Series heater parts and under the CZ 150 through 400 heater range.
How do I know the switch has failed and not the board?
A switch that feels loose, has to be held to work, or only makes contact in part of its travel is the switch. Test for continuity across the terminals in each position before condemning the control board.
Is this a genuine Hayward part?
Yes. It is the Hayward OEM switch, part number CHXTSW1931.
