This OEM replacement contactor is the factory-specified part for the Carrier C4850C50ZW090110 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will not respond to a cooling call, leaving you with warm air or a completely unresponsive outdoor unit. This listing replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120.
Compatibility: Designed for the Carrier C4850C50ZW090110 packaged gas/electric or cooling unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — confirm your existing part number or data plate specs before ordering. Our fitment team is available to verify compatibility prior to purchase. Order today for same-day shipping and get your system back online fast.
