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 a genuine OEM single-pole definite-purpose contactor (OEM part number 1172472) for the ICP WCA3244GKG100 condensing unit. Rated at 30 amps with a 24-volt control coil and an integrated shunt, the contactor is the electrically controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the coil receives 24V from the control circuit, the contacts close and send line voltage to the outdoor unit. A failing contactor is one of the most common causes of an outdoor unit that will not start, hums but never engages, or short-cycles. Pitted, welded, or chattering contacts and a burned-out coil are typical end-of-life symptoms.

Compatibility

Designed as the factory replacement for the ICP WCA3244GKG100 air conditioner condensing unit. Because it is a 30A 1-pole 24V definite-purpose contactor, it also serves as a direct fit for many comparable Heil, Tempstar, and Comfortmaker outdoor units that originally shipped with OEM part 1172472. Always confirm the existing contactor's amp rating, pole count, and coil voltage before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any terminals.
Access — Remove the electrical access panel on the condensing unit.
Document — Photograph all wiring connections to the existing contactor before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor, reconnect each wire exactly as photographed, and confirm the coil leads land on the 24V terminals.
Test — Restore power and call for cooling; confirm the contacts pull in cleanly and the compressor and fan start.

Signs You Need a Replacement

Outdoor unit hums or buzzes but the compressor and fan never start.
Visibly pitted, burned, or welded contacts that stick closed.
Chattering or rapid clicking when the thermostat calls for cooling.
No 24V pull-in even with confirmed control voltage at the coil.

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.
