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 a genuine OEM single-pole definite purpose contactor (part number 1172472) for the ICP / Tempstar / Heil WCA4244GKA101 condensing unit. The contactor is the high-voltage switch that powers the compressor and condenser fan motor when the thermostat calls for cooling. A 24-volt signal from the control circuit energizes the coil, which pulls the contacts closed and sends line voltage to the outdoor unit. This part is rated at 30 amps with a 24V coil and includes an integrated shunt for dependable single-pole operation. Typical failure symptoms include a humming or buzzing condenser, contacts that stick closed so the unit runs continuously, burnt or pitted contacts, or an outdoor unit that simply will not energize.

Access - Remove the service panel from the condensing unit to reach the control compartment.
Document - Take a clear photo of all wiring before disconnecting any leads.
Remove - Label and disconnect the line, load, and coil wires, then unfasten the old contactor from its bracket.
Install - Mount the new contactor and reconnect each wire to match your photo, landing the 24V coil leads on the coil terminals.
Test - Restore power and call for cooling; verify the contactor pulls in and the compressor and fan run 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.
