Overview

This OEM 2-pole, 30-amp definite purpose contactor (part 1178074) is the primary switching relay for the ICP/Tempstar/Heil RHS048L0CA0AAA heat pump. Its 24V control coil energizes when the thermostat calls for cooling or heating, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. A failing contactor is one of the most common no-cool/no-heat service calls. Symptoms include pitted or welded contacts that keep the compressor running, a chattering or buzzing coil, or contacts that fail to close so the outdoor unit stays silent while the thermostat calls. The 30A rating and 24V coil match the factory specification, ensuring correct pull-in and reliable operation.

Access — Remove the condenser service/control panel.
Document — Photograph all line, load, and coil wiring before disconnecting.
Remove — Note terminal positions, transfer wires one at a time off the old contactor, then unbolt it from the bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the coil pulls in and the compressor and fan energize on a call.
