Overview

This is a genuine OEM 2-pole, 30-amp contactor with a 24-volt coil (ICP part number 1171554) for the ICP/Tempstar/Heil RGS303SFFA0AAAA. The contactor is the electrical switch that makes and breaks line voltage to the compressor and condenser fan motor on every call for cooling. Its 24V coil is energized by the low-voltage control circuit, pulling the contacts closed to deliver power. Over thousands of cycles the contacts pit, burn, and weld, leading to no-cool calls or a system that won't shut off. A fresh contactor restores reliable switching and protects downstream components.

Access — Remove the service panel to expose the contactor.
Document — Photograph all line, load, and 24V coil connections before removing any wires.
Remove — Transfer wires one at a time, or pull all leads after labeling, then unscrew the old contactor from its base.
Install — Mount the new 2-pole 30A contactor and reconnect each wire to its matching terminal per your photo.
Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan energize.
