Overview

This is the genuine OEM 2-pole, 30-amp contactor (part number 1171554) with a 24-volt coil for the ICP / Heil / Tempstar RGS303LSAA0AAAA system. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed, allowing line voltage to pass to the outdoor unit. Contactors are wear items: their contacts pit, burn, and weld over time from the constant arcing of switching high inrush loads. A failed contactor is one of the most common no-cooling failures, causing a unit that won't start, hums, chatters, or runs continuously even after the thermostat is satisfied.
