Overview

This OEM 2-pole, 30-amp contactor (PN 1178074) is the genuine replacement for the ICP Tempstar Heil RHH090L0BA0AAAA heat pump. The contactor is an electrically operated switch with a 24V coil that energizes the compressor and condenser fan when the thermostat calls for cooling or heat-pump operation. Over time the contact points pit, weld, or burn — causing the unit to fail to start, run continuously, or hum without engaging. Replacing a worn contactor is one of the most common and inexpensive HVAC repairs.

How do I replace the contactor on my ICP RHH090L0BA0AAAA — 24V Coil | Ships Today?

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.
