ICP 2-Pole 30A Contactor for RGS102LFAB0AAA — 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp contactor (part number 1178074) with a 24-volt control coil for ICP, Heil, and Tempstar RGS102LFAB0AAA systems. A contactor is the high-current switch that connects line voltage to the compressor and condenser fan motor when the thermostat calls for cooling. The 24V coil pulls the two main contacts closed; when the call ends, a spring opens them. Over thousands of cycles the contacts pit, arc, and eventually weld closed or burn open. Welded contacts keep the compressor running continuously even with the system off, while burned or open contacts prevent the outdoor unit from starting at all. A loud hum, chattering, or visible arcing at the contactor are classic late-stage failure signs.

Specifications

Compatibility

Direct OEM fit for the RGS102LFAB0AAA and other ICP/Heil/Tempstar/Comfortmaker systems that use a 2-pole 30A 24V 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, then verify zero voltage with a multimeter.
2. Access — Remove the electrical access panel on the condensing unit.
3. Document — Photograph every wire and terminal before disconnecting.
4. Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its mount.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan start.
