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 (part number 1172472) is the switching relay that controls the compressor and condenser fan on your ICP WPA3244000RKC1 condensing unit. Rated for 30 amps with a 24-volt control coil and equipped with an integrated shunt, it energizes the high-voltage load whenever the thermostat calls for cooling. Contactors are one of the most common failure points in a condenser: the contact points pit, arc, and weld over thousands of cycles. Typical symptoms of a failing contactor include a unit that hums but won't start, a compressor that runs continuously because the contacts have welded shut, chattering or buzzing at the contactor, or burnt and discolored terminals. Replacing it with the correct OEM-spec part restores reliable, clean switching.

Compatibility

Engineered as a direct OEM replacement for the ICP/Heil/Tempstar/Comfortmaker WPA3244000RKC1 heat pump and related condensing units. As a standard 1-pole 30A/24V definite purpose contactor it also serves as a correct replacement across many residential split-system condensers in the same family. Always confirm your existing contactor's pole count, amp rating, and coil voltage before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the contactor terminals.
Access — Remove the condenser service/control panel to expose the contactor.
Document — Photograph every wire and terminal location before disconnecting anything.
Remove — Note line, load, and 24V coil leads, disconnect them, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo, ensuring the 24V coil leads land on the coil terminals.
Test — Restore power and call for cooling; confirm the contactor pulls in cleanly and the compressor and 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.
