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 is the genuine OEM contactor for the ICP / Tempstar / Heil RGS303HSAA0AAAA, available in two ratings: part 1171554 (CONTACTOR 2-Pole 30A, 24V coil) and part 1183142 (CONTACTOR 3-Pole 60A, 24V coil). The contactor is the high-current switch that the 24V control circuit uses to energize the compressor and condenser fan. When the thermostat calls for cooling, the 24V coil pulls the contacts closed, sending line voltage to the load. Contactors fail from arcing, pitted or welded contacts, and worn coils — leading to a unit that won't start, won't shut off, or chatters. Replacing a worn contactor restores clean switching and protects the compressor from damaging voltage drops.

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.
