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.

Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This genuine OEM 2-pole definite purpose contactor (part #1178074) is the primary switching relay for the outdoor unit on the ICP / Tempstar / Heil RHH072S0AA0AAAA heat pump. Rated at 30 amps with a 24-volt coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. When the low-voltage coil receives 24V from the control circuit, the contactor pulls in and closes the line-voltage contacts that power the compressor. A failed contactor is one of the most common no-cool and no-heat service calls — symptoms include a unit that hums but won't start, pitted or welded contacts, a buzzing or chattering sound, or an outdoor unit that simply stays dead while the indoor blower runs.

Access — Remove the service panel from the outdoor unit's electrical compartment.
Document — Photograph all wire connections before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo (line in, compressor/fan loads out, 24V to coil terminals).
Test — Restore power and confirm the contactor pulls in on a thermostat call and the compressor energizes.
