Overview

This is a genuine OEM 2-pole definite-purpose contactor (part number 1178074) for the ICP / Tempstar / Heil RGS090SRAB0AAA gas furnace and packaged unit. Rated at 30 amps with a 24-volt control coil, the contactor is the electrically-controlled switch that energizes the high-voltage circuit to the blower, condenser fan, or compressor whenever the thermostat calls. When the coil is energized, its magnetic field pulls the contacts closed; when the call ends, springs open them. Pitted, welded, or chattering contacts are among the most common causes of a no-start or intermittent-operation service call.

Is this contactor compatible with Bryant or Payne too?
