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 #1172472) is the electrical switch that energizes the outdoor unit on your ICP/Heil/Tempstar WJH324000KTP0A2 heat pump. When the thermostat calls for cooling or heating, the 24-volt control coil pulls in the contacts, sending line voltage to the compressor and condenser fan motor. It is rated for 30 amps and includes an integrated shunt for reliable single-pole switching. A failing contactor is one of the most common no-cooling/no-heat service calls — symptoms include a humming or chattering outdoor unit, pitted or welded contacts that won't release, or a system that won't start at all.

Compatibility

Engineered for the ICP/Heil/Tempstar/Comfortmaker WJH324000KTP0A2 heat pump and shared across many Carrier-family condensing units and heat pumps using a 24V, 30A single-pole contactor. Always verify your existing contactor's amp and coil-voltage rating before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker; verify zero voltage at the contactor terminals 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 — Label and disconnect each wire, then unscrew the old contactor from the bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo (line in, compressor/fan load out, 24V to coil terminals).
Test — Restore power, call for cooling, and confirm the contactor pulls in and the unit starts cleanly.

Is this contactor compatible with Bryant or Payne too?

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.
