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 OEM 1-pole, 30-amp contactor with a 24V coil and integrated shunt (part number 1172472) for the ICP / Tempstar / Heil WPG4364090LKB1 packaged unit. The contactor is the high-current switch that energizes the compressor and outdoor fan whenever the 24V control circuit calls for cooling. When the thermostat closes, 24V pulls the coil in and the contacts pass line voltage to the load; the shunt provides a continuous power path for the crankcase heater or accessory circuit even when the contacts are open. Contacts pit, weld, and burn over time, leading to a compressor that won't start, chatters, or runs continuously. This direct-fit OEM contactor restores clean, reliable switching.

Access — Remove the control / service panel to reach the contactor.
Document — Photograph every line, load, coil, and shunt connection before disconnecting.
Remove — Label and remove the wires, then unbolt the burned or pitted contactor from the mounting rail.
Install — Mount the new 1-pole contactor, land the line and load conductors, and connect the 24V coil leads and shunt exactly per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with the compressor and fan starting normally.

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.
