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 RGS210HRCA0AAAA covers the definite-purpose contactors used to switch line power to the compressor and condenser fan. It includes a 2-pole 30-amp contactor (1171554) and a 3-pole 40-amp contactor (1172449), both with a 24-volt control coil. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and energizes the high-voltage loads; when the call ends, a spring opens them. Contactors are among the highest-wear electrical parts in an HVAC system because the contacts make and break under load thousands of times per season, eventually pitting, welding shut, or failing to close. A bad contactor is a leading cause of a unit that hums but won't start, a compressor that won't shut off, or buzzing at the contactor itself.

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.
