Overview
This OEM definite-purpose contactor switches high-voltage power to the compressor and condenser fan on the ICP / Tempstar / Heil RGS303HRFA0AAAA system. A 24V control signal energizes the coil, pulling the contacts closed to start the outdoor unit. Two configurations are offered: part 1171554 — a 2-pole 30A contactor, and part 1183142 — a 3-pole 60A contactor, both with a 24V coil. Contactors fail from arcing that pits and welds the contacts, or from a burned-out coil. Symptoms include the outdoor unit not starting, a buzzing or chattering contactor, contacts that stick closed so the unit won't shut off, or visibly burned, pitted, or melted contact points. A fresh contactor restores clean, reliable switching and protects the compressor.
