ICP 2-Pole 30A Contactor for RGS243HEAA0AGAA — 24V Coil | Ships Today

Overview

This is a genuine OEM definite-purpose contactor for the ICP RGS243HEAA0AGAA system. The contactor is the electromechanical relay that switches line voltage to the compressor and condenser fan motor whenever the 24-volt control circuit calls for cooling. When the thermostat energizes the coil, an electromagnet pulls the contacts closed and power flows to the outdoor unit; when the call ends, a spring opens the contacts. This listing covers the OEM-specified contactor family for this model — 2-pole 30A (PN 1171554), 3-pole 40A (PN 1172449), and 3-pole 60A (PN 1183142) — all with a 24V coil. Contactors fail from pitted or welded contacts, a burned-out coil, insect intrusion, or chattering caused by low control voltage. Symptoms include a unit that will not start, a loud hum or buzz at the outdoor unit, or a compressor that runs continuously because the contacts have welded shut.

Specifications

Compatibility

Engineered as the factory-spec contactor for the ICP RGS243HEAA0AGAA and shared ICP-family equipment sold under the Heil, Tempstar, and Comfortmaker brands. Match the pole count and amp rating to the contactor currently installed in your unit before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the service panel on the condensing unit or air handler.
3. Document — Photograph every wire and terminal before disconnecting anything.
4. Remove — Note line, load, and 24V coil leads, then transfer wires one at a time or pull the old contactor and label leads.
5. Install — Mount the new contactor, land each wire on the matching terminal per your photo, and confirm the coil leads are on the 24V terminals.
6. Test — Restore power, place a call for cooling, and verify the contacts pull in cleanly with no chatter.

Signs You Need a Replacement

• Outdoor unit hums or buzzes but the compressor and fan will not start.
• Visible pitting, arcing, or burnt/welded contacts.
• Compressor runs nonstop because the contacts are stuck closed.
• Coil is open or distorted, or the contactor chatters during a call.
