Product details

The Jandy R0458601 is the flame sensor rod for the Legacy model LRZE pool and spa heater. It is the genuine Jandy part.

What it does

The flame sensor rod sits in the burner flame and tells the heater control that ignition succeeded. Without that signal the control assumes the burner never lit and closes the gas valve as a safety measure. The result an owner sees is a heater that fires, runs for a few seconds, and then shuts itself down again.

When to replace it

A rod that is heavily oxidized, cracked at the ceramic, or no longer producing a reliable signal after cleaning is due for replacement. The hot surface ignitor for the Legacy LRZE is a separate part, and many techs change both while the burner tray is open.

Questions and answers

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

Which heater is this for?
The Jandy Legacy model LRZE pool and spa heater.
What does the flame sensor rod do?
It confirms to the heater control that the burner has actually lit. If the control gets no flame signal it shuts the gas back off.
My heater lights then shuts down. Is this the part?
That pattern often points at flame sensing. A rod that is dirty, cracked or failed is the usual suspect, though the ignition and gas train should be checked as well.
Is this a genuine Jandy part?
Yes. It is Jandy part R0458601.
