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 definite purpose contactor energizes the compressor and condenser fan motor in your ICP RHS150S0EA0AAAA heat pump. When the thermostat calls, the 24V control circuit pulls the contactor coil in, closing the 2-pole, 30-amp contacts and feeding line voltage to the outdoor unit. Rated 30A per pole with a 24-volt coil, it withstands the high inrush of compressor start-up across thousands of cycles. The contacts eventually pit, burn, and arc-weld, and debris or insects can wedge under them. Typical failure signs include a buzzing or chattering outdoor unit, a compressor that hums but won't start, a condenser fan that runs continuously, or a completely dead outdoor unit while the indoor blower still runs. This is one of the most common and cost-effective HVAC repairs.

Compatibility

Engineered as a direct OEM fit for the ICP / Heil / Tempstar / Comfortmaker RHS150S0EA0AAAA heat pump condensing unit. ICP shares this 2-pole 30A 24V contactor platform across many RHS-series single-stage outdoor units, making it a frequent replacement on comparable condensers. Verify your existing contactor is 2-pole with a 24V coil before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the condenser unit's electrical access panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note line (L1/L2), load (T1/T2), and 24V coil wire positions, then transfer wires one at a time or unbolt the old contactor.
Install — Mount the new contactor and reconnect each wire exactly per your photo.
Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter.
