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 ICP contactor (part number 1176763) is the 40-amp, 2-pole electrical switch that energizes the compressor and condenser fan motor in your ICP/Tempstar/Heil WCH3614GKC110 heat pump. When the thermostat calls for cooling or heating, the 24V control coil pulls in the contactor, closing the line-voltage contacts that power the outdoor unit. Years of cycling pit, arc, and burn the contacts — a failing contactor is one of the most common reasons an outdoor unit hums but won't start, chatters, or sticks closed and runs continuously. Replacing it restores clean, reliable switching.

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note line, load, and 24V coil terminals, transfer wires one at a time, and unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo.
Test — Restore power and verify the contactor pulls in cleanly and the compressor and fan start.

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.
