ICP Definite Purpose Contactor for RGS244HRAA0AAAA — 24V Coil, 30A/40A/60A | Ships Today

Overview

This OEM definite-purpose contactor set fits the ICP / Heil / Tempstar RGS244HRAA0AAAA system and is offered in three configurations: 2-pole 30A (1171554), 3-pole 40A (1172449), and 3-pole 60A (1183142), each with a 24V coil. The contactor is the electrically operated switch that closes on a 24V signal to deliver line voltage to the compressor and condenser fan motor. Pitted contacts, a chattering or buzzing coil, or contacts that weld closed are the most common failure modes — symptoms range from a unit that won't start to one that won't shut off.

Specifications

Compatibility

Designed for the ICP RGS244HRAA0AAAA platform shared by the Heil, Tempstar, and Comfortmaker brands. Select the pole count and amp rating that matches the contactor already in your unit (1171554, 1172449, or 1183142) — verify the printed rating 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 unit's electrical-access service panel.
3. Document — Photograph all line, load, and 24V coil wiring before disconnecting.
4. Remove — Transfer one wire at a time or label each, then unbolt the old contactor.
5. Install — Mount the new contactor and reconnect every wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in cleanly on a call and that the compressor and fan energize.

Signs You Need a Replacement

• Loud buzzing, humming, or chattering from the contactor.
• Burnt, pitted, or welded contacts that won't open or close.
• Compressor or condenser fan won't start despite 24V at the coil.
• System fails to shut off because the contacts are stuck closed.
