The Pentair 461100 repair kit is intended for compatible Pentair MasterTemp and Sta-Rite Max-E-Therm high performance heaters in 175, 200, 250, 300, 333, and 400 model sizes. It is not designed for the MasterTemp 125 heater.

Before ordering, verify the heater model, BTU size, fuel type, serial information, and the specific failed component. Heater parts can vary by model, production date, and configuration.

Installation Notes

Heater diagnosis and repair should be performed by a qualified pool professional or licensed technician. Gas, electrical, ignition, combustion, and water system components must be serviced according to manufacturer instructions and applicable codes.

Always turn off power and gas before servicing the heater. Do not replace components unless the cause of failure has been properly diagnosed. Repeated component failure may indicate an underlying issue such as poor water flow, improper gas pressure, blocked venting, wiring problems, or incorrect installation.

  • Maintain proper pool water chemistry to help protect heater components.
  • Keep the pool filter clean to maintain proper water flow through the heater.
  • Inspect electrical connections, sensors, switches, and wiring during service.
  • Have gas pressure, water flow, and combustion conditions checked if heater problems continue after parts are replaced.
