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 single-pole contactor (Part #1172472) is the main switching relay for the ICP WCA3364GKB1 condensing unit. Rated at 30 amps with a 24-volt coil and a built-in shunt, it closes to energize the compressor and condenser fan whenever the thermostat calls for cooling. Over thousands of switching cycles the high-amperage arcing pits, burns, or welds the contacts. Typical failure symptoms include a unit that hums but won't start, a condenser fan that runs nonstop after the cooling call ends, audible chattering at the contactor, or no outdoor unit operation at all. This low-cost relay restores dependable compressor and fan engagement.

Compatibility

Direct OEM-fit replacement for the ICP / Tempstar / Heil WCA3364GKB1 air conditioning condenser. As a definite purpose 1-pole 30A contactor with a 24V coil, it is also a functional match for comparable ICP-family residential split-system condensers using the same switching specification. Verify amperage, pole count, and coil voltage against the contactor you are removing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage across the contactor terminals with a multimeter before touching any wiring.
Access — Remove the condenser unit's electrical service panel to expose the contactor.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Transfer or label one wire at a time, then unscrew the contactor from its bracket and detach all leads.
Install — Mount the new contactor in the same orientation and reconnect each wire to the matching terminal per your photo, landing the 24V coil leads on the coil screws.
Test — Restore power and call for cooling. Confirm the contactor pulls in cleanly and the compressor and condenser fan energize.

Signs You Need a Replacement

Outdoor unit hums or buzzes but the compressor and fan will not start.
Visibly pitted, burned, or melted contact points.

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.
