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 the genuine OEM 1-pole, 30-amp definite-purpose contactor (part 1172472) with a 24V coil and integrated shunt for the ICP/Heil/Tempstar WJA330000K000B1 condensing unit. The contactor is the electrically controlled switch that closes the high-voltage circuit to the compressor and condenser fan whenever the thermostat sends a 24V call for cooling. The built-in shunt maintains the line connection on the unswitched leg. Contactors are high-wear parts: the contacts arc and pit every cycle, and over years they burn, weld shut, or stop pulling in. Symptoms include a humming or chattering contactor, contacts stuck closed so the unit never shuts off, or pitted contacts that prevent the compressor from starting.

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.
