My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This OEM contactor set for the ICP / Tempstar / Heil RHS183L0BA0AAAA heat pump covers both the 2-pole 30A contactor (part 1171554) and the 3-pole 40A contactor (part 1172449), each with a 24V coil. The contactor is the heavy-duty switch that closes when the thermostat calls for cooling or heating, sending line voltage to the compressor and condenser fan motor. Its contacts carry high current every cycle, so they pit, burn, and weld over time. A failing contactor causes a humming or chattering unit, a compressor that won't start, or one that won't shut off. Installing the correct OEM 24V-coil contactor restores reliable switching and protects the compressor.

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.
