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

OEM part 1172472 is a genuine single-pole contactor rated 30 amps with a 24-volt control coil and an integrated shunt, built for the ICP / Tempstar / Heil WCH5184GKA100 heat pump. The contactor is the electromechanical switch that delivers line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump heating. When the 24V coil energizes, the silver-alloy contacts close and power the outdoor unit; when the call ends, a spring opens them. Pitted, welded, or chattering contacts are a leading cause of a no-cool or no-heat outdoor unit, hard-starting compressors, and loud buzzing at the condenser.

Access — Remove the condenser control-panel service cover.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Transfer line, load, and 24V coil leads one at a time, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo, confirming tight connections.
Test — Restore power, call for cooling, and verify the contacts pull 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.
