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 an OEM definite-purpose contactor for the ICP / Tempstar / Heil RGS243HFAA0AAAA system, covering part 1171554 (2-pole, 30A, 24V coil), 1172449 (3-pole, 40A, 24V coil), and 1183142 (3-pole, 60A, 24V coil). The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan motor when the thermostat sends a 24-volt signal to its coil. As the most frequently cycled high-load component in the system, contactors wear out — contacts pit, weld, or chatter, and the coil can burn open. A bad contactor is a leading cause of an outdoor unit that won't start or won't shut off. Specs: 24 VAC coil; 2-pole 30A, 3-pole 40A, and 3-pole 60A ratings available.

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.
