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 30-amp contactor (part #1172472) with a 24V coil and shunt is the switching relay for the ICP/Heil/Tempstar WJH330000K000A1 heat pump. When the thermostat calls for cooling or heating, the 24V coil energizes and pulls the contacts closed, sending line voltage to the compressor and outdoor fan motor. The shunt provides the constant connection on the line side typical of single-pole designs. Contactors are one of the most common outdoor-unit failures: the contacts pit and burn from arcing over thousands of cycles, the coil can fail open, or insects/debris can jam the plunger. A failed contactor causes a unit that hums but won't start, chattering, or an outdoor unit that runs continuously and won't shut off.

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.
