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 RGS303HRAA0AAAA system covers both the 2-pole 30A contactor (part 1171554) and the 3-pole 60A contactor (part 1183142), each with a 24V control coil. A contactor is the high-current relay that the thermostat's 24V signal energizes to switch line voltage to the compressor and condenser fan motor. Its contacts carry the full load current every time the system runs, so they eventually pit, arc, and weld. Common failure symptoms include a system that will not start, a unit that will not shut off because the contacts have welded closed, loud chattering or buzzing at the contactor, or burned and pitted contact surfaces. Replacing a worn contactor restores clean switching and protects the compressor from voltage problems.

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.
