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 40 amp definite-purpose contactor (OEM part #1176763) is the primary switching relay for your ICP WCH4604GKA110 heat pump. When the thermostat calls for cooling or heating, the 24-volt control coil energizes and pulls the contactor's main contacts closed, sending line voltage to the compressor and condenser fan motor. Rated at 40 amps, it is built to handle the locked-rotor inrush current of the outdoor unit. Failure symptoms include a unit that won't start, chattering or buzzing at the outdoor cabinet, pitted or welded contacts, and burnt or melted terminals. A contactor with welded contacts can keep the compressor running even when the system should be off, while a failed coil leaves the outdoor unit completely dead.

Compatibility

Engineered as a direct OEM replacement for the ICP / Tempstar / Heil WCH4604GKA110 heat pump condensing unit. It also fits many ICP-family outdoor units that use a 40A single-pole, 24V-coil contactor. Always confirm your amp rating, pole count, and coil voltage against the failed part before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel to expose the control compartment.
Document — Photograph all wires before disconnecting anything.
Remove — Note the line, load, and coil terminals, then transfer wires one at a time off the old contactor and unscrew it from the bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the contactor pulls in on a call and that the compressor and fan start.

Signs You Need a Replacement

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.
