ICP 2-Pole 30A Contactor for RGS120LDAB0AAA — 24V Coil | Ships Today

Overview

This is the genuine OEM 2-pole, 30 amp contactor with a 24V coil (part #1178074) for the ICP/Heil/Tempstar RGS120LDAB0AAA. The contactor is the electrically operated switch that uses a low-voltage 24V signal from the thermostat to close two line-voltage poles, energizing the compressor and condenser fan. Because it cycles thousands of times per season, the contacts eventually pit, burn, or weld. Failure shows up as a system that won't start, a humming contactor that won't pull in, or contacts that stick closed and won't let the unit shut off.

Specifications

Compatibility

Engineered for the ICP RGS120LDAB0AAA and shared ICP-built platforms sold under the Heil, Tempstar, Comfortmaker, and Day & Night brands. Confirm 2-pole, 30A, and a 24V coil against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the unit disconnect and breaker; verify zero voltage with a multimeter.
2. Access — Remove the electrical access panel.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer wires one at a time to the new contactor, or label and disconnect, then unbolt the old contactor.
5. Install — Mount the new contactor and land each wire on the matching terminal per your photo.
6. Test — Restore power and run a cooling cycle; confirm the contactor pulls in and the compressor/fan start.
