Overview

This is a genuine OEM 2-pole definite purpose contactor (part number 1178074) for ICP / Tempstar / Heil RGS090SEAA0AGAA gas furnace and condensing systems. The contactor is an electrically operated switch that uses a 24V control signal from the thermostat or control board to energize the 30-amp line-voltage circuit feeding the compressor and condenser fan motor. When the coil energizes, the contacts pull in and complete the high-voltage path. Common failure symptoms include pitted or welded contacts, a humming or chattering coil, no-cooling calls where the outdoor unit will not start, or burnt terminals from arcing.

Is this contactor compatible with Bryant or Payne too?
