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 genuine OEM 1-pole, 30-amp definite-purpose contactor (part 1172472) with a 24V coil and integrated shunt is the switching relay for the ICP/Heil/Tempstar WPG4304060LKA1 packaged unit. When the thermostat calls for cooling, the 24V control signal energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. The built-in shunt keeps power routed correctly to the auxiliary load. Contactors endure thousands of make/break cycles, and over time the contacts pit, weld, or chatter. A failed contactor is a leading cause of a condenser that won't start, won't shut off, or hums and buzzes without engaging.

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.
