OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50Z3090110

This OEM contactor is the factory-specified replacement for the Carrier C4850C50Z3090110 packaged unit. The contactor functions as the primary high-voltage relay in your system — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the contacts and delivering line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't start, runs continuously without shutting off, or produces a loud chattering or buzzing sound from the electrical panel inside the unit.

• Specs: 2-Pole configuration | 24V AC coil voltage | High-amperage contacts rated for compressor load | Direct OEM replacement for part numbers HN53CB115, HN53HF122, and HN53HG120
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips that resist pitting and arcing far longer than generic alternatives. Generic contactors often use lower-grade contact materials that degrade faster under the high inrush current of a compressor start cycle, leading to premature failure and potential compressor damage.
• Install Difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and wire labels or a phone camera to document wiring before removal. Transfer one wire at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier C4850C50Z3090110 packaged unit and cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Confirm coil voltage and pole configuration on your unit's data plate before ordering. Not sure if this is the right part?
