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

The OEM 1172472 is a 1-pole, 30A definite-purpose contactor with a 24V coil and built-in shunt, used to switch line power to the compressor and condenser fan on ICP, Heil, and Tempstar units. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and energizes the outdoor unit; the shunt maintains the unswitched leg for proper circuit operation. Over time the contacts pit, burn, or weld, and the coil can fail — causing a unit that will not start, chatters, or stays running after the call ends. This direct OEM replacement restores clean, reliable switching and protects the compressor from low-voltage and arcing damage.

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.
