Overview
This genuine OEM definite-purpose contactor for the ICP / Tempstar / Heil RGS210HTCA0AAAA is available in two ratings: a 2-pole 30-amp (part 1171554) and a 3-pole 40-amp (part 1172449), both with a 24-volt control coil. The contactor is the main switching relay for the outdoor condensing unit — when the thermostat calls for cooling, 24V energizes the coil, pulling the contacts closed and sending line voltage to the compressor and condenser fan motor. Because it makes and breaks high current on every cycle, the contactor is one of the most common HVAC failure points: contacts pit, burn, and weld over time, and ants or debris can lodge under the plunger. A failing contactor causes hard starts, chatter, a unit that won't start, or a unit that won't shut off.
