ICP 24V Contactor for RGS303HFAB0AGAA – OEM 2-Pole 30A & 3-Pole 60A 1171554 / 1183142 | Ships Today

Overview

These OEM definite-purpose contactors switch the high-voltage power to the compressor and condenser fan on your ICP Tempstar Heil RGS303HFAB0AGAA unit. Part 1171554 is a 2-pole 30A contactor and part 1183142 is a 3-pole 60A contactor, both with a 24V control coil energized by the thermostat or control board. When the coil pulls in, the contacts close and feed line voltage to the load. Contactors fail from contact pitting and welding caused by arcing, or from a burned-out coil. Typical symptoms include the outdoor unit not starting, a humming or chattering contactor, contacts that stick closed so the unit won't shut off, or visibly burned/pitted contacts. Installing the correct OEM contactor restores clean, reliable switching.
