Overview

This OEM 2-pole contactor (part number 1178074) is the main power-switching relay for the ICP RHH102L0CA0AAAA heat pump. Rated at 30 amps with a 24-volt control coil, it energizes the compressor and outdoor fan motor each time the thermostat calls for heating or cooling. The 24V coil generates the magnetic pull that closes the contacts and feeds line voltage to the condensing unit. Constant high-amperage arcing eventually pits and welds the silver contacts, while the coil can open or short with age. A worn contactor is the most common reason an outdoor unit hums without starting, chatters, or cycles erratically. This exact OEM-spec 30A 2-pole, 24V replacement restores dependable, safe switching.
