Overview

This OEM contactor (part #1178074) is the genuine 2-pole, 30-amp, 24-volt-coil contactor for the ICP/Tempstar/Heil RHH036H0BA0AAAA heat pump. The contactor is the high-current switch that powers the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24V signal energizes the coil, pulling the contacts closed to pass line voltage to the outdoor unit. Over time the contacts pit, burn, and stick — or the coil weakens — causing the unit to chatter, fail to start, or run continuously even after the call ends. Replacing a worn contactor is a routine, high-value repair that prevents compressor damage.
