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 single-pole definite-purpose contactor (part number 14306504) is the primary switching relay for the ICP/Heil/Tempstar YA018 condensing unit. Rated at 14 amps with a 24-volt control coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. The 24V coil pulls a set of silver-alloy contacts closed to pass line voltage to the outdoor components. Over many thousands of cycles those contacts pit, arc, and can weld together, while the coil itself can open or weaken. A failing contactor is one of the most common no-cool service calls — symptoms include a buzzing or chattering outdoor unit, a compressor that won't start, contacts stuck closed so the unit runs continuously, or a completely dead condenser on a cooling call.

Compatibility

This contactor is the factory-specified switching relay for the ICP YA018 outdoor unit and the equivalent Heil, Tempstar, and Comfortmaker badged versions of the same platform. It is a direct, plug-in OEM replacement — no rewiring or adapters required. Confirm your existing contactor is a single-pole, 14A, 24V coil unit before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching wiring.
Access — Remove the service panel from the condensing unit to expose the contactor and control wiring.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Note wire positions, disconnect the spade and lug terminals, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo (line in, load out, 24V on the coil).
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with the compressor and fan running without chatter.

Signs You Need a Replacement

Loud buzzing, humming, or chattering from the outdoor unit
Compressor and condenser fan won't start on a cooling call
Pitted, burned, or welded contacts on the old part

Is this contactor compatible with Bryant or Payne too?

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.
