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 single-pole 40A contactor with a 24V coil is the main switching relay for the ICP / Tempstar / Heil WJH460000KTP0A1 condensing unit. When the thermostat calls for cooling, the 24V control signal energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor and condenser fan. Because it switches high current thousands of times per season, the contactor's contacts eventually pit, burn, or weld together. Pitted contacts cause hard starts and chattering; welded contacts keep the compressor running even when the thermostat is satisfied. A failed 24V coil leaves the contactor unable to pull in at all. Replacing it with the correct 40A OEM contactor restores clean, reliable switching and protects the compressor from voltage drop and short-cycling.

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.
