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 2-pole contactor for the ICP / Tempstar / Heil RGS101HECB0AAA serves as the high-voltage switch that energizes the compressor and condenser fan motor on a call for cooling. Two factory ratings are available: the 30-amp version (part 1178074) and the 40-amp version (part 1178211), both driven by a 24-volt control coil. When the thermostat calls for cooling, 24V from the control board pulls the contactor's armature in, closing both poles and sending line voltage to the outdoor unit. Contactors are a common failure point because their contacts arc and pit over thousands of cycles, eventually welding closed or burning open. Replacing a worn contactor with the correct OEM rating restores reliable switching and protects the compressor from chatter and voltage drop.

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.
