Overview
This is the genuine OEM 2-pole, 30-amp definite-purpose contactor (P/N 1178074, CONTACTOR 2P 30A 24V) for the ICP / Heil / Tempstar RHH072L0BA0AAAA heat pump. The contactor is the switch that delivers high-voltage line power to the compressor and condenser fan motor whenever the thermostat sends a 24V call. Its electromagnetic coil pulls the contacts closed; over thousands of cycles the contacts pit, arc, and weld, while the coil can burn open. When that happens the outdoor unit either won't start at all or won't shut off. Typical failure symptoms include a humming or buzzing contactor, chattering pull-in, a condenser that runs continuously, visibly burned or pitted contacts, and a compressor that draws power but never engages. This direct-replacement contactor restores reliable, arc-free switching with a 24VAC coil and 30A-rated silver-alloy contacts.
