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 single-pole definite purpose contactor (OEM part #1172472) is the electrically-controlled switch that powers the compressor and condenser fan motor on your ICP/Tempstar/Heil WCA3482GKN300 condensing unit. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, pulling the 30-amp line-voltage contacts closed to start the compressor. This unit is a 1-pole design rated at 30 amps with a 24V coil and includes an auxiliary shunt. Common failure symptoms include a unit that hums but won't start, contacts that are pitted or welded shut (compressor runs continuously), chattering, or no compressor operation at all despite a 24V call for cooling.

Compatibility

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker. Verify zero voltage across the line terminals with a multimeter before touching any wiring.
Access — Remove the condenser service/electrical panel to expose the contactor.
Document — Take a clear photo of all line, load, and coil wiring before disconnecting anything.
Remove — Label and disconnect the line (L1), load (T1), and the two 24V coil wires. Unscrew the contactor from its mounting bracket and lift it out.
Install — Mount the new contactor, then reconnect each wire to the matching terminal per your photo. Confirm the coil leads land on the 24V coil terminals.
Test — Restore power and call for cooling. Confirm the contactor pulls in cleanly and the compressor and condenser fan start.

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.
