ICP 2-Pole 30A Contactor for RGS120LRBA0AAA — 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp contactor (part number 1178074) with a 24V control coil for the ICP / Tempstar / Heil RGS120LRBA0AAA unit. The contactor is the electrically controlled switch that delivers line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V coil energizes, it pulls the contacts closed and powers the high-voltage loads. A failed contactor is one of the most common causes of a system that won't start, hums but won't engage, or runs continuously because the contacts have welded shut. Pitted, burned, or chattering contacts also cause hard starts and premature compressor wear.

Specifications

Compatibility

Direct-fit replacement for the ICP RGS120LRBA0AAA and shared across many ICP, Tempstar, Heil, Comfortmaker, and Arcoaire platforms using a 2-pole 30A / 24V coil contactor. Always confirm your existing contactor's amperage and coil voltage against the unit's wiring diagram before installing.

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 condensing unit service panel.
3. Document — Photograph all wire positions before disconnecting anything.
4. Remove — Label and detach line, load, and 24V coil leads; unscrew the old contactor from the bracket.
5. Install — Mount the new contactor, then reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contacts pull in on a cooling call and the compressor/fan energize.

Signs You Need a Replacement

• System hums but the compressor and fan won't start.
• Burned, pitted, or melted contacts visible on the old part.
