ICP 2-Pole 30A Contactor for RGS120LSAB0AAA — 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part #1178074) is the switching relay that energizes the compressor and condenser fan circuit in your ICP/Tempstar/Heil RGS120LSAB0AAA system. Rated for 30 amps per pole with a 24-volt control coil, it pulls in when the thermostat calls for cooling and passes line voltage to the load. Pitted, welded, or chattering contacts are one of the most common HVAC failures. Symptoms include a system that won't start, a contactor that hums but won't pull in, or a unit that runs continuously because the contacts have welded closed.

Specifications

Compatibility

Direct OEM fit for the ICP RGS120LSAB0AAA platform and the shared chassis sold under the Tempstar, Heil, and Comfortmaker labels. Always confirm your existing contactor is a 2-pole, 30A, 24V-coil unit 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 service panel.
3. Document — Photograph every wire and terminal before disconnecting.
4. Remove — Transfer the line, load, and 24V coil leads one at a time from the old contactor, then unscrew it from the bracket.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor energizes.

Signs You Need a Replacement

• Burned, pitted, or welded contacts
• Loud humming or buzzing but the contactor won't pull in
