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 1-pole 30-amp contactor (part #1172472) with a 24V coil and integrated shunt is the electrical relay that switches line power to the compressor and condenser fan on your ICP WCH5304GKA200. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, delivering high voltage to the outdoor unit. Contactors wear out faster than almost any other component because their contacts arc and pit on every cycle. A failed contactor leaves the outdoor unit dead, causes buzzing or chattering, or welds shut and runs the compressor non-stop. The integrated shunt provides the correct circuit path for this ICP application. Watch for a humming unit that won't start, blackened or pitted contacts, and a relay that clicks but won't hold in.

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?

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.
