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 (part #1172472) for the ICP/Tempstar/Heil WJA324000KTP0A1 condensing unit. Rated for 30 amps with a 24-volt control coil and an integrated shunt, the contactor is the electrical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls in a set of heavy-duty contacts that carry line voltage to the outdoor unit. Because the contacts arc and carry high current on every cycle, they are one of the most common HVAC failure points. Worn, pitted, or welded contacts cause the compressor to chatter, fail to start, or run continuously. Replacing a tired contactor is an inexpensive way to restore reliable operation and protect the much costlier compressor.

Compatibility

Designed for the ICP-family WJA324000KTP0A1 air conditioning condenser. Also serves as a direct OEM replacement across many ICP, Tempstar, Heil, and Comfortmaker outdoor units that use a 1-pole 30A 24V contactor.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser unit's electrical access panel.
Document — Photograph all wire positions before disconnecting anything.
Remove — Note line, load, and 24V coil terminals, then unfasten the old contactor from its bracket and transfer wires one at a time.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor/fan start.

Signs You Need a Replacement

Loud buzzing, humming, or chattering at the outdoor unit.
Compressor or condenser fan won't 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.
