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

Genuine OEM 2-pole definite-purpose contactors for the ICP Tempstar Heil RGS091HTBA0AAAA. This listing covers part 1178074 (2-pole, 30A, 24V coil) and part 1178211 (2-pole, 40A, 24V coil). The contactor is the electrically operated switch that energizes the compressor and condenser fan motor when the 24V control signal calls for cooling. Its contacts carry high line-voltage current, so they wear, pit, and burn over time. A failing contactor causes hard starts, chattering, welded contacts that won't release, or a system that won't start at all.
