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 30A Contactor with shunt (Part #1172472) is the electrical switch that sends line voltage to the compressor and condenser fan motor in your ICP / Heil / Tempstar WJH324000K000A1 heat pump. A 24V coil pulls the contacts closed whenever the thermostat calls and the transformer energizes the control circuit; the integrated shunt provides a defined current path for the run capacitor / control wiring. Rated for 30 amps, it handles the inrush and running current of a residential heat pump. Contactor contacts are a wear item — they pit, arc, and weld over thousands of cycles. A failed contactor causes a unit that won't start, chatters, or won't shut off (welded contacts). Replacing the contactor on a no-start call is fast, inexpensive, and restores reliable switching.

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.
