Overview

This OEM 2-pole, 30-amp contactor (part number 1178074) with a 24-volt coil switches line-voltage power to motors and components in the ICP Tempstar Heil RGS120HSAB0AAA. When the 24V control signal energizes the coil, the contacts close and pass power; when it drops out, the contacts open. Over time the contacts pit, burn, and weld from arcing, or the coil fails open. Symptoms include a system that won't start, chattering or buzzing at the contactor, contacts that stick closed so the unit runs constantly, or visible burning and pitting on the contact faces.

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.
