Overview

This is a 2-pole definite purpose contactor for the ICP/Heil/Tempstar RHS102H0BB0AAAA heat pump. The contactor energizes the compressor and condenser fan motor whenever the thermostat calls for heating or cooling. A 24-volt signal pulls in the coil, closing the line-voltage contacts and powering the outdoor unit. Available in 30-amp (OEM 1178074) and 40-amp (OEM 1178211) ratings. Common failure symptoms include a humming or chattering outdoor unit, pitted or welded contacts, a compressor that won't start, or a unit that runs continuously because the contacts won't release.

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.
