OEM Carrier Single-Pole Contactor 1-Pole 24V 30A — HN51KC024 for Model PH13NR04200GACAA

This OEM Carrier contactor (part# HN51KC024) is the factory-specified replacement for the Carrier PH13NR04200GACAA heat pump condenser unit. The contactor is the high-voltage relay that completes the circuit to the compressor and condenser fan motor every time your thermostat calls for cooling or heating. When the contacts pit, burn, or weld shut — or the 24V coil fails — the unit either won't turn on at all, runs continuously without responding to the thermostat, or trips the breaker. Replacing a failed contactor is one of the most common and cost-effective HVAC repairs.
