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 genuine OEM single-pole contactor (ICP part 1173690) is the electromechanical switch that energizes the condensing unit on your ICP / Tempstar / Heil WPG3604115LKC1 packaged unit. When the thermostat calls for cooling, the 24V control circuit pulls in the coil, closing the 40-amp line-voltage contacts that feed the compressor and condenser fan motor. Rated for 40A and a 24V coil, it handles the inrush and running current of residential and light-commercial condensing equipment. A failing contactor is one of the most common no-cool service calls: pitted, welded, or burned contacts cause hard starts, chatter, or a unit that won't run at all, while a burned-out coil leaves the system completely dead on a cooling call.

Access — Remove the unit's electrical access panel.
Document — Photograph all line, load, and coil wiring before disconnecting anything.
Remove — Note wire positions, pull the spade and line connections off the old contactor, and unscrew it from the bracket.

Test — Restore power, place a cooling call, and confirm the contactor pulls in cleanly and the compressor and fan energize.

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.
