Overview

This is a genuine OEM 2-pole, 30-amp definite purpose contactor (OEM part #1178074) for the ICP / Tempstar / Heil RHH048H0XA0AAAA heat pump. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. A 24V control signal pulls in the coil, closing the two line-voltage poles and powering the outdoor unit. Contacts are rated for 30A continuous duty. Common failure symptoms include a unit that won't start, chattering or buzzing at the outdoor unit, pitted or welded contacts that keep the compressor running, or a clicking relay that never closes the circuit.

Access — Remove the electrical access panel on the condensing unit.
Document — Photograph all wire positions on the line and load sides before disconnecting anything.
Remove — Move wires one at a time to the new contactor, or label them; unscrew the old contactor from the bracket.
Install — Mount the new contactor, transfer the 24V coil wires and line/load conductors exactly per your photo, and tighten all terminals.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize.
