ICP 2-Pole 30A Contactor for RGS121LSBA0AAAA — 24V Coil | Ships Today

Overview

This is the genuine OEM 2-pole definite purpose contactor (part number 1178074) for the ICP RGS121LSBA0AAAA condensing unit. Rated for 30 amps with a 24-volt control coil, the contactor is the electromechanical switch that energizes the compressor and condenser fan motor on every call for cooling. When the 24V coil receives signal from the thermostat, it closes the contacts and sends line voltage to the high-amperage components. Worn contactors are a leading cause of no-cool service calls — pitted or welded contacts, a failed coil, or chattering points prevent reliable starting and can damage the compressor. A fresh OEM contactor restores crisp, dependable switching and protects the rest of the system.
