Overview

This OEM 2-pole definite purpose contactor (part #1171554) is the switching relay that powers the compressor and condenser fan in your ICP/Tempstar/Heil RGS243SEAA0AAAA system. Rated for 30 amps per pole with a 24V control coil, it energizes when the thermostat calls for cooling, closing both line-voltage poles to start the outdoor unit. The high inrush current of every compressor start gradually pits, arcs, and welds the contact points. A failing contactor is one of the most common no-cool service calls: symptoms include a buzzing or chattering outdoor unit, contacts stuck closed that won't shut off, or contacts that fail to pull in at all. Replacing this inexpensive part is cheap insurance against a far costlier compressor failure.
