ICP 2-Pole 30A 24V Contactor for RGS102LSCA0AAA — OEM 1178074 | Ships Today

Overview

This is a genuine OEM 2-pole 30-amp contactor with a 24-volt coil (part number 1178074) for the ICP / Heil / Tempstar RGS102LSCA0AAA. The contactor is the electrically operated switch that connects line voltage to the controlled load when the 24V control coil is energized. Its double-pole contacts carry up to 30 amps and open and close on every cycle, so they are among the hardest-working components in the system. Over time the contacts pit, burn, or weld, and the coil can fail open. Typical symptoms include a system that will not energize on a valid call, contacts that chatter or buzz, a loud hum from the coil, or contacts that stick closed and prevent the load from shutting off.

Specifications

Compatibility

Direct-fit replacement for the ICP / Heil / Tempstar / Comfortmaker RGS102LSCA0AAA and related RGS-series units that use a 2-pole 30A 24V contactor. Verify the amp rating and coil voltage stamped on your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the service panel to expose the contactor.
3. Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
4. Remove — Transfer one wire at a time, or label each, then unscrew the old contactor from its mount.
5. Install — Mount the new contactor and reconnect every wire exactly as photographed.
6. Test — Restore power, initiate a call, and confirm the contactor pulls in and the load energizes.
