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 WPA4364000RKA1 condensing unit. Rated at 30 amps with a 24-volt control coil and built-in shunt, the contactor is the electrical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V coil is energized, the contacts close and pass line voltage to the outdoor unit; when the call ends, a spring opens the contacts. Pitted, welded, or chattering contacts are one of the most common no-cool failures in residential air conditioning, and a failed coil will leave the outdoor unit completely dead even though the indoor blower runs.

Compatibility

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage across the line terminals with a multimeter.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph all wires and terminal positions before disconnecting anything.
Remove — Transfer one wire at a time, or label each lead, then unscrew the old contactor from its bracket and lift it out.
Install — Mount the new contactor in the same orientation and reconnect every wire exactly per your photo, confirming line, load, and the two 24V coil leads.
Test — Restore power, call for cooling, and verify the contacts pull in and the compressor and condenser 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.
