This OEM contactor is the factory-specified replacement for the Carrier C4850C50ZG050500 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to energize the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a worn coil, or contacts that weld shut — the result is an AC system that won't turn on, runs continuously without shutting off, or buzzes loudly without cooling. Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120.
Compatibility: Designed for the Carrier C4850C50ZG050500 packaged unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our team is available to confirm fitment prior to purchase. Order today and your part ships the same business day.
