Overview

This OEM contactor (part 1178074, CONTACTOR 2P 30A 24V) is the high-voltage switching relay for the ICP/Heil/Tempstar RHH102H0CA0AAAA heat pump. A 24V control signal from the thermostat energizes the coil, pulling in two 30-amp poles that send line voltage to the compressor and condenser fan motor. Contactors fail from pitted or welded contacts, a burned-out coil, or insect/debris intrusion that keeps the points from closing. Common symptoms include a condenser that won't start, chattering or buzzing at the contactor, contacts that weld shut so the unit never cycles off, and visible arcing or burnt terminals.
