OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C48Z8075610

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.

  • Specs: 2-pole configuration | 24V control coil | High-amperage contacts rated for compressor load | Direct OEM replacement for part numbers HN53CB115, HN53HF122, and HN53HG120
  • OEM vs Generic: OEM contactors feature factory-grade contact alloy and coil winding tolerances, ensuring proper pull-in voltage and long contact life. Generic contactors often use lower-grade contact materials that arc and pit prematurely, leading to repeat failures within a single season.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our stocked warehouse.

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. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48Z8075610?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48Z8075610. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier C4850C48Z8075610?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
