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 30-amp contactor with shunt (part #1172472) is the high-voltage relay that powers the compressor and outdoor fan on the ICP / Heil / Tempstar WCH3194GKC100 heat pump. When the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor and condenser fan motor. The built-in shunt provides the proper electrical path for this 1-pole design. Contactors are among the most common failure points in any outdoor unit: the contacts pit, burn, and weld over thousands of cycles, while ants and insects love to nest under the plunger. A failing contactor shows up as a unit that hums but won't start, chatters, or won't shut off because the contacts have welded together. Replacing it with the correct OEM 30A contactor restores clean, reliable switching.

Compatibility

Designed for the ICP / Heil / Tempstar WCH3194GKC100 heat pump and other WCH-series condensing units that use the 1172472 single-pole 30A contactor. The same contactor is used across many Comfortmaker and Arcoaire outdoor units of similar tonnage. Confirm pole count, amp rating, and 24V coil before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the outdoor unit's electrical access panel.
Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
Remove — Transfer one wire at a time, or label each lead, then unscrew the old contactor from its mounting bracket.
Install — Mount the new 1172472 contactor and reconnect every line, load, and coil wire exactly per your photo.
Test — Restore power and start a cooling or heating cycle; confirm the contactor pulls in cleanly and the compressor and fan energize.

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.
