This OEM contactor is the factory-specified replacement for the Carrier C4850C48Z8075610 packaged HVAC unit. The contactor is a high-voltage relay that bridges the low-voltage signal from your thermostat to the high-voltage power supply for the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — your system will receive a call for cooling but the compressor and fan will not energize, leaving you with warm air or no response at all.
Compatibility: Designed for use in Carrier model C4850C48Z8075610 packaged units. This part supersedes and replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — order with confidence knowing all three numbers resolve to this same factory-correct component. Verify your existing contactor's pole count and coil voltage against your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase.
