ICP 40A Contactor for RGX060KMCA0AAA — 2-Pole 40 Amp OEM 1176763 | Ships Today

Overview

This OEM 40-amp contactor (part number 1176763) is the factory switching relay for the ICP / Heil / Tempstar RGX060KMCA0AAA. The contactor uses a 24V control-coil signal from the thermostat to close its main contacts and energize the high-voltage load. Over time the contacts pit, burn, and weld from the inrush current of every cycle, and the coil can fail open. Symptoms include a system that won't start, a chattering or buzzing contactor, or contacts that stick closed and keep the unit running even when there's no call. Replacing a worn 40A contactor restores clean, reliable switching and protects the rest of the electrical system.

Specifications

Compatibility

Engineered as the exact-fit 40A contactor for the ICP / Heil / Tempstar / Comfortmaker RGX060KMCA0AAA and many other Heil-built systems using a 2-pole 24V-coil contactor. Verify the amp rating, pole count, and 24V coil against your failed contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter at the contactor line terminals.
2. Access — Remove the electrical-compartment service panel.
3. Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
4. Remove — Transfer wires one at a time, then unscrew and lift out the old contactor.
5. Install — Mount the new 40A contactor and reconnect each wire to the matching terminal per your photos.
6. Test — Restore power, call for cooling/operation, and confirm the contactor pulls in cleanly with no chatter.

Signs You Need a Replacement
