Pentair Pro Service Package Master | MasterTemp & Max-E-Therm | 461100

Description

The Pentair Pro Service Package – Master (461100) is the OEM master repair kit for the MasterTemp and Max-E-Therm High Performance gas heater series, covering the most commonly replaced electrical, sensing, and sealing components in a single, organised hardcase.

IMPORTANT: THIS IS A KIT — MULTIPLE COMPONENTS INCLUDED
This listing is for the complete Pro Service Package – Master kit. It contains multiple individual components supplied in a reusable hard case. You are not purchasing a single part. Review the component list below before ordering to confirm you need this master-level kit.

IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
This kit contains gas ignition, high-voltage electrical, and safety-critical control components. Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.

The 461100 Pro Service Package – Master consolidates the most frequently replaced components of the MasterTemp and Max-E-Therm heaters into one stocked kit. When a heater presents with ignition failure, control faults, sensor errors, or water/air pressure issues, this package provides the OEM replacement parts needed to complete a thorough diagnostic service without multiple part orders.

Poolaroo Pro Tip

Service professionals keep the 461100 kit stocked for MasterTemp and Max-E-Therm call-outs precisely because heater fault codes rarely point to a single failed component — a failed thermistor often accompanies a degraded pressure switch, and an ignition control fault can mask a failing air flow switch. Having the complete set on-site eliminates the delay of a second visit. Before opening the case, confirm your heater model number on the rating plate and verify it is a 175/200/250/300/333, or 400 BTU variant — this kit is not designed for the 125,000 BTU (125K) model.
