Overview
This OEM single-pole definite purpose contactor (part #1172472) is the switching relay that energizes the compressor and condenser fan motor in your ICP/Heil/Tempstar WCH3482GKR1 heat pump. On a call from the thermostat, the 24V control circuit energizes the contactor coil, closing the contacts to send line voltage to the compressor. Rated for 30 amps with a 24-volt coil and an integrated shunt, it handles the high inrush current of compressor startup through thousands of cycles. Typical failure symptoms include a unit that hums but won't start, contacts that pit or weld shut so the compressor runs nonstop, chattering, or an audible buzz from the contactor. Burned contacts are among the most common causes of no-cool and no-heat service calls.
