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 number 1172472) is a 1-pole, 30-amp definite-purpose contactor with a 24-volt coil and integrated shunt, built for the ICP/Tempstar/Heil WTA3302000RKA1 condensing unit. The contactor is the electrical switch that sends line voltage to the compressor and condenser fan motor every time the thermostat calls for cooling. The 24V control signal energizes the coil, pulling the contacts closed to start the outdoor unit. With thousands of switching cycles the contacts pit, arc, and eventually weld or burn open, and the coil itself can fail — producing a unit that hums without starting or one that won't shut off. A new contactor is a fast, low-cost fix for these common condenser faults.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the condenser service/access panel.
Document — Photograph all wire positions on the old contactor before disconnecting anything.
Remove — Transfer the line, load, and 24V coil leads off the old contactor one at a time, then unscrew it from the mounting bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the 24V coil leads are secure.
Test — Restore power, call for cooling, and verify the contacts pull in and the compressor and fan start.

Signs You Need a Replacement

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.
