About This Item
OEM Wiring Harness for Pentair MasterTemp and Max-E-Therm Heaters
The Pentair Heater Wiring Harness (461107) is the OEM replacement electrical harness for the MasterTemp 125 and Max-E-Therm heater series, restoring proper internal electrical connections to your heater's control and ignition circuit.
⚠️ IMPORTANT: LICENSED 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.
⚠️ IMPORTANT: VERSION / DATE QUALIFIER — MAX-E-THERM COMPATIBILITY
For Max-E-Therm heaters, this harness is compatible with single-voltage wire harness models manufactured prior to 2004. Verify your heater's manufacture date and wiring configuration before ordering.
The wiring harness routes and protects the internal electrical connections between the heater's control board, ignition system, and operational components. A damaged or failed harness can cause intermittent ignition faults, control board errors, or complete heater shutdown. Replacing the harness with the correct OEM part restores the original wiring configuration and ensures proper signal integrity throughout the heater's electrical circuit.

Pro Tip
Before ordering, confirm your heater's voltage configuration and manufacture date — particularly for Max-E-Therm units, where this harness applies only to single-voltage models built before 2004. The manufacture date is typically printed on the heater's rating label inside the front access panel. If the original harness is still partially intact, photograph the connector layout and routing path before removal; this reference will assist your technician during installation and ensure the replacement is routed identically to the factory configuration.
