ICP 2-Pole 30A Contactor for RGS120HRBB0AAA — 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part number 1178074) is the electromagnetic switch that energizes the compressor and condenser fan motor in your ICP RGS120HRBB0AAA system. Rated for 30 amps with a 24-volt coil, it closes its line-voltage contacts whenever the thermostat calls for cooling, then opens them to cut power when the call ends. Over time the silver contact points pit, arc, and weld from the thousands of make-and-break cycles a contactor sees each season. Common failure symptoms include a condenser that hums but won't start, contacts that chatter, a unit that runs continuously because the contacts have welded shut, or visible burn marks and melted housing around the terminals. Replacing a worn contactor is one of the most common and least expensive HVAC repairs.

Specifications

Compatibility

Engineered as a direct OEM fit for the ICP / Tempstar / Heil RGS120HRBB0AAA gas furnace and its companion condensing unit. As a 2-pole 30A / 24V definite purpose contactor it also serves as a correct replacement across many comparable ICP-family systems using the same coil voltage and amperage class.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage across the contactor terminals with a multimeter.
2. Access — Remove the condenser service panel to expose the electrical compartment.
3. Document — Photograph every wire and terminal location before disconnecting anything.
4. Remove — Note the line, load, and 24V coil leads, transfer them one at a time, then unscrew the old contactor from the bracket.
5. Install — Mount the new contactor, reconnect each wire exactly per your photo, and confirm the coil leads land on the 24V terminals.
6. Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter and the compressor and fan start.

Signs You Need a Replacement

• Condenser hums but the compressor and fan will not start.
• Burned, pitted, or melted contact points and terminals.
• Contactor chatters or buzzes loudly when energized.
• Unit runs nonstop because the contacts have welded closed.
