Overview

This is a genuine OEM 2-pole definite-purpose contactor (part number 1178074) for the ICP / Tempstar / Heil RGS091STAA0AAAA furnace and matched condensing equipment. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor when the 24V control signal is applied to its coil. Rated at 30 amps per pole with a 24V coil, it carries the high-voltage line load while being safely controlled by the low-voltage thermostat circuit. A failing contactor is one of the most common no-cool service calls: pitted or welded contacts, a chattering coil, or burnt terminals all prevent reliable compressor operation.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
