ICP 2-Pole 30A Contactor for RGS102SFAA0AAA — 24V Coil | Ships Today

Overview

This is the OEM 2-pole, 30-amp definite-purpose contactor (part number 1178074) with a 24V coil for the ICP/Tempstar/Heil RGS102SFAA0AAA equipment. The contactor is the high-current switch that energizes the compressor and condenser fan motor when the 24-volt control circuit calls for cooling. The thermostat sends 24V to the coil, which pulls the contacts closed and sends line voltage to the load. Over time the contacts pit, corrode, and weld from repeated arcing, and the coil can burn out. Failure symptoms include a system that won't start, contacts that chatter or buzz, a contactor that won't pull in, or a unit that runs continuously because the contacts have welded shut.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil RGS102SFAA0AAA system and equivalent ICP-built units across the Tempstar, Heil, Comfortmaker, and Arcoaire families that use a 2-pole 30A 24V-coil contactor. Confirm pole count, amp rating, and coil voltage against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker; verify zero voltage with a multimeter.
2. Access — Remove the unit's electrical access panel.
3. Document — Photograph all line, load, and coil wiring before disconnecting.
4. Remove — Transfer wires one at a time, then unscrew and remove the old contactor.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photos.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize.

Signs You Need a Replacement
