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.

Overview

This genuine OEM 2-pole definite-purpose contactor fits the ICP / Tempstar / Heil RGS091HDAA0AAAA system and its paired condensing unit. The contactor is the heavy-duty switch that delivers line voltage to the compressor and condenser fan motor on every cooling call. Its 24-volt coil energizes from the control circuit, pulling the contacts closed so the high-voltage load can run. This listing includes both OEM part 1178074 (2-pole, 30A, 24V) and OEM part 1178211 (2-pole, 40A, 24V) so you can match the precise amperage of your original. A failing contactor is one of the most common air conditioning service calls — pitted contacts, a buzzing coil, or welded points all stop the system from cycling properly.
