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

These OEM definite-purpose contactors switch line-voltage power to the compressor and condenser fan on the ICP RHS243S0FA0AAAA heat pump. A contactor is an electrically operated switch: a 24V signal from the thermostat/control energizes the contactor coil, which closes the high-current contacts and powers the compressor and fan. Two options cover this platform — part 1171554, a 2-pole 30A contactor with a 24V coil, and part 1172449, a 3-pole 40A contactor with a 24V coil. Contacts are wear items; arcing slowly pits and burns them until they no longer close cleanly. A failing contactor causes the outdoor unit to fail to start, chatter or buzz, weld its contacts closed (unit won't shut off), or short-cycle.

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.
