Overview

This OEM contactor fits the ICP / Tempstar / Heil RGS243HFFA0AAAA system and is offered in the factory-spec ratings used on this platform: a 2-pole 30A 24V contactor (part 1171554), a 3-pole 40A 24V contactor (part 1172449), and a 3-pole 60A 24V contactor (part 1183142). A contactor is an electrically operated switch — when the 24V coil is energized by the control circuit, its contacts close to send line voltage to the compressor and condenser fan. Pitted, welded, or chattering contacts are a leading cause of a unit that won't start, trips breakers, or short-cycles. Match the amperage and pole count to your original part for an exact replacement.
