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 is a genuine OEM single-pole definite purpose contactor (part number 1172472) for the ICP / Tempstar / Heil WJA330000KTP0A2 condensing unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24-volt control signal pulls in the coil, closing the 30-amp line-voltage contacts and delivering power to the high-voltage components. This unit includes an integrated shunt for dependable operation. When a contactor fails, the most common symptoms are a compressor that will not start, chattering or buzzing at the contactor, pitted or welded contacts, or an outdoor unit that runs continuously because the contacts have fused closed. Replacing a worn contactor is one of the most common and cost-effective HVAC service repairs.

Document — Photograph every wire and terminal connection before disconnecting anything.
Remove — Note the line, load, and 24V coil leads, label them, and unscrew the old contactor from the bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize.

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.
