Overview

This is a genuine OEM 2-pole definite-purpose contactor (part number 1178074) for the ICP/Heil/Tempstar RGS102HFCB0AAA system. The contactor is the electrically-operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. It carries a 30-amp current rating across two poles and uses a 24-volt control coil energized by the low-voltage circuit from the control board. When the coil pulls in, the contacts close and line voltage passes through to the outdoor unit; when the call ends, a spring opens the contacts. Worn, pitted, or chattering contacts are one of the most common causes of a unit that will not start, hums but does not run, or trips the breaker.
