Product Overview

Keep commonly needed heater repair parts organized and ready for service with the Pentair 461100 Pro Service Heater Master Kit. This professional package brings together water-system and electrical-system parts for compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters in a reusable hard case.

Built for service technicians who maintain multiple heaters, the kit provides a convenient supply of components used in diagnosis and repair. Individual parts can be replenished as they are used. This is a parts assortment, not a complete replacement heater or a single repair that fixes every heater fault.

Check the kit contents and the heater’s model-specific parts diagram before selecting a component for a repair. Heater revisions may require a particular replacement part.

Warranty & Compatibility

Professional Service Guidance

Diagnose the heater fault before replacing parts. Service involving electrical power, gas combustion, or the pressurized water system should be performed by a qualified pool-heater professional following Pentair instructions and applicable codes. Disconnect power, shut off the gas supply when required, and relieve water pressure before opening the heater.

For a technician servicing only one known failure, an individual replacement component may be more appropriate. Kit 461100 is intended as a stocked service assortment for ongoing work.
