Overview

This OEM 2-pole definite-purpose contactor switches line voltage to the compressor and condenser fan in your ICP Tempstar Heil RHS090L0CA0AAA heat pump. When the thermostat calls for cooling or heating, the 24V coil pulls the contacts closed and energizes the outdoor unit. Over time the contacts pit and burn from arcing, and the coil can fail open — leaving you with a unit that hums but won't start, chatters, or won't shut off. Replacing a worn contactor is one of the most common heat-pump service repairs. This unit is offered in 30A (part 1178074) and 40A (part 1178211) ratings, both with a 24V coil, matching the OEM specification.

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.
