OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50AW02751

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C4850C50AW02751 packaged unit. The contactor acts as the main switching device that energizes the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted or burned contacts, a welded contactor, or a failed coil — the system either won't turn on at all, runs continuously without shutting off, or draws excessive amperage that damages downstream components.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amp capacity | Direct OEM replacement for part numbers HN53CB115 and HN53HF122
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated to factory specifications, ensuring correct pull-in voltage and long contact life. Generic contactors frequently use lower-grade contact materials that pit and weld prematurely, leading to repeat failures within one or two seasons.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our warehouse — get your system back online fast.

Compatibility: Engineered as a direct OEM drop-in replacement for Carrier C4850C50AW02751 packaged units. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always verify coil voltage and pole configuration against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AW02751 — Ships Today?

How do I replace the contactor on my Carrier C4850C50AW02751 — Ships Today?
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.
