Pentair 120/240 Volt Plug Kit | MasterTemp / Max-E-Therm Heaters | 42001-0105S

Description

The Pentair 120/240 Volt Plug Kit (42001-0105S) is the OEM replacement electrical plug kit for Pentair MasterTemp and Max-E-Therm pool heaters.

⚠️ IMPORTANT: KIT LISTING — MULTIPLE PIECES INCLUDED
This listing is a kit, not a single plug. All components included in the kit are intended to be replaced together as a set.

⚠️ IMPORTANT: HIGH-VOLTAGE HEATER COMPONENT — PROFESSIONAL INSTALLATION REQUIRED
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.

This plug kit provides the correct 120/240 volt electrical connection points for the heater’s power supply interface. Damaged, corroded, or failed plugs can interrupt power delivery to the heater control board and heating circuit, causing the unit to fail to start or operate intermittently. Replacing the plug kit with the OEM part restores the original electrical connection integrity specified for these heater models.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

Before ordering, confirm the voltage configuration of your heater installation — 120V and 240V supply configurations use different wiring arrangements, and this kit is rated for both. Match the part number stamped on your existing plug assembly to 42001-0105S before adding to cart. Because this kit involves mains-voltage connections, all installation and replacement work must be performed by a licensed pool professional or qualified electrician — do not attempt to replace electrical heater components without proper certification.
