ICP Contactor for WPG3602090LKB1 — 1-Pole 40A 24V Coil | Ships Today

Overview

This OEM single-pole contactor (part 1173690) is the high-voltage switch that energizes the compressor and condenser fan on your ICP WPG3602090LKB1 whenever the thermostat calls for cooling. Rated 40 amps with a 24V coil, it pulls in when the low-voltage control circuit applies 24VAC to the coil and closes the line-voltage contacts. Contactors wear out from arcing and mechanical cycling: pitted or welded contacts cause the unit to run continuously, while a burned-out coil leaves the system dead even though control power is present.

Specifications

Compatibility

Designed for the ICP WPG3602090LKB1 packaged unit and shared across Heil, Tempstar, and Comfortmaker condensing units that use a 1-pole 40A 24V-coil contactor. Confirm pole count, amp rating, and coil voltage against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter on the line and load terminals.
2. Access — Remove the control-panel service cover.
3. Document — Photograph the line, load, and 24V coil connections before disconnecting.
4. Remove — Transfer the spade and lug connections off the old contactor and unbolt it from the panel.
5. Install — Mount the new contactor and reconnect the line, load, and coil leads exactly per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan energize.

Signs You Need a Replacement

• Unit won't start on a cooling call despite 24V at the coil.
• Pitted, burned, or welded contacts that won't open.
• Loud chattering or buzzing from the contactor.
• Compressor runs continuously and won't shut off.
