ICP Single-Pole Contactor for WPG4304060RKA1 — 30A 24V w/ Shunt | Ships Today

Overview

This genuine OEM single-pole contactor (part number 1172472) is the direct replacement for the ICP / Tempstar / Heil WPG4304060RKA1. A contactor is the high-voltage switch that powers the compressor and condenser fan. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, which pulls the contacts closed and sends line voltage to the load. This unit is rated 30 amps with a 24V coil and includes the integrated shunt. Contactors are among the most common HVAC failure points: their contacts arc and pit with every cycle, and over thousands of cycles they can weld shut (so the unit never stops) or burn open (so it never starts). A pitted or chattering contactor causes hard starts, buzzing, and erratic operation that stresses the compressor.

Specifications

Compatibility

Direct-fit for the ICP WPG4304060RKA1 and the Tempstar, Heil, and Comfortmaker units built on the same platform. Confirm pole count, amp rating, and 24V coil against your existing contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the electrical service panel.
3. Document — Photograph all line, load, and coil wires before disconnecting.
4. Remove — Unscrew the mounting screws and transfer wires one at a time, or label each lead before removal.
5. Install — Mount the new contactor and reconnect each wire to its matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in cleanly with no chatter when the system calls.
