ICP 1-Pole 40A Contactor for WPG4604115RKA1 — 24V Coil | Ships Today

Overview

This OEM definite-purpose contactor (part 1173690) is the high-voltage switch that powers the compressor and condenser fan on your ICP/Heil/Tempstar WPG4604115RKA1. When the 24V control circuit energizes the coil, the contactor's electromagnet pulls the contacts closed and sends line voltage to the compressor; when the thermostat is satisfied, the coil de-energizes and the contacts open. Rated 40 amps with a single pole and a 24V coil, it is built for the inrush and continuous load of a residential package unit. Contactors are a leading cause of no-cool calls: pitted or welded contacts can stop the unit from starting, cause it to chatter, or weld closed so the compressor never shuts off. A burnt coil simply will not pull the contacts in even with 24V present.

Specifications

Compatibility

Direct OEM fit for the ICP/Heil/Tempstar/Comfortmaker WPG4604115RKA1 and ICP-family package units specifying a 1-pole, 40A, 24V-coil contactor. Verify pole count, amp rating, and coil voltage against your existing part 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 service panel to reach the contactor.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer wires one at a time or tag them, then unbolt the old contactor from the bracket.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the coil pulls the contacts in cleanly on a call for cooling.

Signs You Need a Replacement

• Pitted, burnt, or welded contacts
