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 1-pole, 30-amp definite purpose contactor with a 24V coil and shunt (ICP part #1172472) is the switching relay that energizes the compressor and condenser fan in ICP, Heil, Tempstar, and Comfortmaker WPG-series packaged units. When the thermostat calls for cooling, 24 volts energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor and fan motor. The single-pole design switches one leg while the shunt maintains the circuit on the other, and the 30A rating handles the locked-rotor and run currents of the equipment. Contactors wear out from arcing, pitting, and coil failure — the most common reason an outdoor unit hums, buzzes, chatters, or fails to start on a cooling call.

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.
