ICP 2-Pole 30A Contactor for RHH120L0EA0AAAA — 24V Coil OEM 1178074 | Ships Today

Overview

The ICP OEM 2-Pole 30A Contactor (part number 1178074) is the factory switching relay that powers the compressor and condenser fan in the ICP / Tempstar / Heil RHH120L0EA0AAAA heat pump. When the thermostat calls for cooling or heating, its 24V coil pulls in the contacts and sends line voltage to the compressor; when the call ends, the contacts open and shut the unit down. Contactors are high-wear items — the contacts pit, burn, and weld over thousands of cycles. A failing contactor causes a unit that won't start, that won't shut off (welded contacts), or that buzzes and chatters. This OEM 2-pole, 30-amp, 24V-coil contactor is a direct drop-in that restores clean, reliable switching.
