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 ICP contactor (part #1171554) is a 2-pole, 30-amp electromechanical switch with a 24-volt control coil. It is the primary high-voltage switching device in your HVAC system: when the thermostat calls for cooling or heating, the 24V coil energizes and pulls the contactor's armature closed, completing the line-voltage circuit to the compressor and condenser fan motor. Because it cycles on and off thousands of times per season, the contactor is one of the most common wear items in any condensing unit. Failure symptoms include a unit that won't start, a chattering or buzzing sound at the contactor, pitted or burned contact points, a melted housing, or a system where the fan and compressor run continuously even after the thermostat is satisfied (welded contacts).

Installation Guide

Safety First – Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage at the contactor terminals with a multimeter.
Access – Remove the service panel from the condensing unit or furnace.
Document – Photograph all line and coil wires before disconnecting anything.
Remove – Note terminal positions (L1/L2/T1/T2 and the two coil terminals), disconnect the wires, and unscrew the old contactor from its bracket.
Install – Mount the new contactor, reconnect each wire exactly per your photo.
Test – Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter.

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.
