This igniter replacement kit is designed specifically for pool and spa heaters from the Pentair Sta-Rite Max-E-Therm and MasterTemp series, covering models rated at 200, 250, 300, and 400 BTUs. Constructed with a robust ceramic base and a durable metal alloy heating element, the kit serves as a direct replacement for the factory igniter component. The materials are chosen to withstand repeated thermal cycling and exposure to the combustion environment, contributing to consistent ignition performance over time. Fitment is precise, as the dimensions and connector configuration match the original part number 77707-0054. The installation process involves removing the old igniter and securing the new unit into the heater’s burner assembly, making it suitable for both do-it-yourself replacements and professional service calls. Quality control during manufacturing ensures that each igniter meets standard electrical resistance and thermal output specifications, providing reliable spark generation each time the heater is activated.

Functionally, this igniter kit delivers a steady, focused flame to ignite the gas burner, enabling the heater to raise water temperature efficiently. Its thermal stability reduces the risk of premature failure, and the straightforward design minimizes compatibility issues with the listed heater models. At a very affordable price point, it offers a cost-effective way to restore heating capability without purchasing an entirely new assembly. This replacement part is ideal for homeowners or service technicians maintaining an existing pool or spa heating system. The core advantage lies in its balance of dependable thermal performance and value, making it a practical choice for maintaining year‑round comfort. As a component‑specific solution, it addresses the most common failure point in gas pool heaters—the igniter—while keeping overall maintenance expenses low.
