ICP Contactor for RGS300HSAA0AAAA — 2-Pole 30A & 3-Pole 60A 24V Coil | Ships Today

Overview

This OEM contactor is the electromagnetic switch that powers the compressor and condenser fan motor in your ICP RGS300HSAA0AAAA system. A 24V signal from the thermostat energizes the contactor coil, pulling the line-voltage contacts closed to start the unit. This listing covers two factory options: part 1171554 (2-Pole, 30A) and part 1183142 (3-Pole, 60A), both with a 24V control coil. When a contactor fails, the most common symptoms are a system that won't start, a humming or chattering relay, or contacts that weld shut and leave the unit running continuously. Pitted, burned, or corroded contacts are the classic sign of wear.

Specifications

Compatibility

Engineered for the ICP RGS300HSAA0AAAA and shared across many Heil, Tempstar, and Comfortmaker condensing units that use the same chassis. Always match the original part number, pole count, and amperage to your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the service panel on the condensing unit.
3. Document — Photograph all line and low-voltage wiring before disconnecting anything.
4. Remove — Note each wire's terminal, disconnect the line, load, and 24V coil leads, then unscrew the old contactor from the bracket.
5. Install — Mount the new contactor and reconnect every wire exactly per your photo, matching pole-for-pole.
6. Test — Restore power and confirm the contacts pull in on a call for cooling and the compressor and fan energize.

Signs You Need a Replacement

• Pitted, burned, or welded contacts
• Loud humming or chattering when the unit calls for cooling
