About This Item

The Pentair Pro Service Package – Master (461100) is the OEM master service kit for the MasterTemp and Max-E-Therm gas heater series, consolidating the most commonly replaced service items into a single, reusable case.

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.

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 parts most frequently replaced during MasterTemp and Max-E-Therm heater service work into one stocked, reusable case, allowing a technician to complete a service visit without separate part orders.

Poolaroo Pro Tip

Service professionals keep the 461100 kit stocked for MasterTemp and Max-E-Therm service calls because it consolidates the commonly replaced service items into a single case, reducing the need for a return trip to source individual parts. Before opening the case, confirm your heater model number on the rating plate and verify it matches one of the MasterTemp 175, 200, 250, 300, or 400 models (NA or LP), or the Max-E-Therm 333 model (NA or LP) — this kit is not designed for other heater series.
