Quick overview
- Genuine Raypak Factory kit 007142F, supplied as a complete flow switch kit.
- Fits P962 through P1826 Covers the larger Raypak heater models in that range.
- A safety device The flow switch is what tells the heater there is water moving through it. Without that proof the control will not light the burner.
- The usual no fire fault A heater that runs the pump and then locks out on flow is very often a failed or fouled switch rather than a real flow problem.
- Kit, not a bare switch Supplied as a kit so the switch goes in complete.
- Do not bypass it Jumping a flow switch to get heat can dry fire the exchanger, which is a far more expensive repair.

Product details
The Raypak 007142F is the genuine flow switch kit for the P962 through P1826 pool heaters. It arrives as a kit, so the switch goes back in complete.
What the flow switch does
A gas heater will not light until it knows water is moving through it. The flow switch is that proof. When flow drops or stops, the switch opens, the control drops out and the burner cannot fire. It is a safety device first: without it, a heater can fire against a static column of water and cook its own heat exchanger.
When to suspect it
A heater that starts, runs briefly and then locks out on flow is the classic symptom. Rule out the ordinary causes first, a blocked filter, a closed or partly closed valve, a low water level, a clogged pump impeller. If flow through the heater is clearly good and the switch still will not make, the switch itself is the fault.
One thing not to do
Do not jumper the switch to get heat for the weekend. That defeats the only thing standing between the burner and a dry exchanger, and the repair that follows costs many times what this kit does.
