Overview

This OEM definite-purpose contactor, ICP part number 1171554, is a 2-pole, 30-amp unit with a 24-volt coil used to switch line power to the compressor and condenser fan on equipment paired with your ICP/Heil/Tempstar RGS243SDEA0AAAA system. The 24V coil energizes from the control circuit and pulls the contacts closed to start the load. Pitted, welded, or chattering contacts and a burned-out coil are the most common failures, leading to a system that won't start or won't shut off.

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.
