This OEM replacement contactor is the factory-specified part for the Carrier C48A206062 packaged unit. The contactor is a high-voltage relay controlled by a 24V signal from the thermostat or control board. When the thermostat calls for cooling, the contactor closes its contacts to send 240V power to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't start — symptoms include a unit that hums without starting, fails to respond to a cooling call, or shows visible pitting and burning on the contact surfaces. OEM part numbers covered: HN53CB115, HN53HF122, and HN53HG120.
Compatibility: Designed as a direct OEM replacement for the Carrier C48A206062 packaged unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Verify coil voltage and pole configuration on your unit's data plate before ordering. Need help confirming fitment? Our HVAC parts specialists verify compatibility before you buy — no guesswork.
