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 genuine OEM contactors for the ICP / Heil / Tempstar RGS210HSCA0AAAA include the 2-pole 30-amp 24V contactor (part 1171554) and the 3-pole 40-amp 24V contactor (part 1172449). A contactor is an electrically operated switch: a 24-volt control signal from the thermostat energizes the coil, which closes the main contacts to deliver line voltage to the compressor and condenser fan motor. The 2-pole 30A unit is typical for standard residential condensing units, while the 3-pole 40A unit handles higher-amperage or three-phase loads. Contactors are high-cycle wear items — every cooling call opens and closes the contacts, so pitting, welding, and coil burnout are common end-of-life failures.

Document — Photograph every line, load, and 24V coil wire before disconnecting.

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.
