This OEM replacement contactor is the factory-specified part for the Carrier C4850C48ZN050600 packaged unit. The contactor acts as a high-voltage relay, receiving a 24V signal from the thermostat and closing the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — whether from pitted contacts, a burned coil, or contacts stuck open or closed — the system either won't start at all or runs continuously regardless of thermostat commands. Replaces OEM part numbers HN53CB115 and HN53HF122.
Compatibility: Designed as a direct OEM replacement for the Carrier C4850C48ZN050600 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always verify pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy.
