Description

The Teledyne Laars R0471500 is the pilot generator for the LRZM model pool and spa heater. It is the genuine Laars part, the same one fitted at the factory.

What it does

On a standing pilot heater the pilot flame has to prove itself before the main burner is allowed to fire. The pilot generator sits in that flame and turns its heat into the small electrical output that holds the gas valve open. As the generator ages its output falls, and the heater starts lighting the pilot only to shut down a moment later.

Before you order

Check the pilot itself first. A partly blocked orifice or a flame that no longer wraps the generator tip produces the same fault and costs nothing to correct. If the pilot burns clean and steady and the heater still drops out, the generator is the part to change.
