ICP 2-Pole 30A Contactor for RGS180SDCA0AAAA — 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp contactor with a 24V control coil (part number 1178074) for the ICP/Tempstar/Heil RGS180SDCA0AAAA system. The contactor is the heavy-duty switch that delivers line voltage to the compressor and condenser fan motor. When the thermostat calls for cooling, 24 volts energizes the coil, pulling the two main contacts closed and powering the outdoor unit. Because it switches high current on every cycle, the contactor's silver contacts gradually pit and burn, and the coil can fail open. Typical symptoms include a condenser that hums but won't start, contacts that buzz or chatter, visibly burned or welded contacts, and an outdoor unit that runs continuously because the contacts have welded shut.

Specifications

Compatibility

Direct OEM replacement for the ICP RGS180SDCA0AAAA and shared across many ICP-family condensing units sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands. Match poles (2), amp rating (30A), and coil voltage (24V) to your existing contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the condenser electrical access panel.
3. Document — Photograph every wire on the line, load, and coil terminals before disconnecting.
4. Remove — Transfer wires off the old contactor and unbolt it from the bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor starts.

Signs You Need a Replacement
