ICP 1-Pole 30A Contactor for WPG4364060LKB1 — 24V Coil w/ Shunt | Ships Today

Overview

This genuine OEM single-pole contactor (part 1172472) is rated 30 amps with a 24V coil and an integrated shunt, used to switch line power to the compressor and condenser fan on the ICP / Tempstar / Heil WPG4364060LKB1 packaged unit. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and energizes the compressor circuit. Over time the contacts pit and burn from arcing, the coil can fail open, or the armature can stick — any of which leaves the outdoor unit silent or buzzing on a cooling call. The built-in shunt provides the correct circuit path for this model's wiring. A contactor with welded or badly pitted contacts is a common cause of a compressor that won't start or won't shut off.

Specifications

Compatibility

Direct-fit replacement for the ICP WPG4364060LKB1 packaged unit and compatible across Tempstar, Heil, and Comfortmaker WPG-series equipment using a 1-pole 30A 24V contactor with shunt. Match the pole count, amp rating, and 24V coil to your original before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and verify zero voltage with a multimeter before touching the contactor.
2. Access — Remove the electrical / control access panel to reach the contactor in the control box.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer the wires off the old contactor one at a time, or remove the contactor and move wires after, then unscrew it from the panel.
5. Install — Mount the new contactor, land each wire on the matching terminal per your photo, including the shunt and 24V coil leads.
6. Test — Restore power and confirm the contactor pulls in cleanly on a cooling call and the compressor starts.

Signs You Need a Replacement

• Compressor and condenser fan won't start on a cooling call.
• Loud buzzing or chattering from the contactor.
• Burnt, pitted, or welded contacts visible on inspection.
