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 WPH4364000RKA1 heat pump. The contactor is the electrically operated switch that energizes the compressor and condenser fan whenever the thermostat calls for cooling. When the 24-volt control coil is energized, the shunted main contacts close and pass line voltage to the outdoor unit. Rated at 30 amps with a 24V coil and built-in shunt, it is the workhorse relay of the condensing unit. Failure symptoms include a unit that won't start, chattering or buzzing at the outdoor unit, pitted or welded contacts, and a compressor that hums but never engages.

Compatibility

Directly fits the ICP/Tempstar/Heil WPH4364000RKA1 heat pump condensing unit. As an OEM 1-pole 30A 24V contactor it also serves as a correct replacement across many ICP-family outdoor units that use the same definite-purpose relay. Always confirm amperage, pole count, and coil voltage against the contactor you are removing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condensing unit's electrical service panel.
Document — Photograph all line, load, and coil wiring before disconnecting.
Remove — Label and disconnect the wires, release the mounting screws, and lift out the old contactor.
Install — Mount the new contactor, reconnect line, load, and 24V coil wires exactly per your photo.
Test — Restore power and call for cooling; confirm the contacts pull in cleanly 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.
