This is the OEM 2-pole definite-purpose contactor for the ICP / Tempstar / Heil RGS091HRAA0AAAA system, available as the 30-amp (part 1178074) and 40-amp (part 1178211) versions, both with a 24-volt control coil. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. The 24V coil pulls the contacts closed, completing the line-voltage circuit to the outdoor unit. Pitted, welded, or chattering contacts are one of the most common causes of a no-cool condition, hard starting, or an outdoor unit that won't shut off. Replacing a worn contactor restores clean, reliable switching and protects the compressor from voltage drop and arcing damage.
