Product details
This is the Jandy R0457501 hot surface ignitor for the Legacy model LRZE pool and spa heater. It is the genuine Jandy OEM part.
What a hot surface ignitor does
Instead of a standing pilot, the heater energizes a ceramic element that glows hot enough to light the gas at the burner. It is a wear part. The element degrades over years of heating and cooling, and eventually it no longer reaches ignition temperature, so the heater goes through its sequence and never lights.
Before you replace it
Watch the ignitor through a start cycle if you can. If it never glows, or glows dull and uneven, it is the part. If it glows properly and the heater still will not light, look at the gas supply and the control side instead.
Fitting
Handle the ignitor by its bracket. The ceramic element is brittle and skin oils shorten its life, so keep your fingers off it and never force it into the mounting.
