OEM Carrier Contactor 2-Pole 24V Coil for Model C4850C50ZZ105610

This OEM replacement contactor is the factory-specified part for the Carrier C4850C50ZZ105610 packaged HVAC unit. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes to supply line-voltage power 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 appear completely unresponsive or fail to cool despite the thermostat calling for cooling. OEM part numbers covered: HN53CB115, HN53HF122, and HN53HG120.

  • Specs: 2-pole design | 24V coil voltage | Rated for compressor and condenser fan motor loads | Factory-matched contact gap and silver alloy contact surface for long service life
  • OEM vs Generic: OEM contactors use factory-spec silver-alloy contacts and precisely wound coils. Generic substitutes are often rated at looser tolerances, leading to premature contact pitting, coil burnout, and nuisance callbacks — especially in high-cycle summer conditions.
  • Install difficulty: 2/5 — Disconnect power at both the disconnect box and the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter. Always photograph existing wiring before removing the old contactor to ensure correct terminal reassignment.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed for the Carrier C4850C50ZZ105610 packaged unit. This part supersedes OEM numbers HN53CB115, HN53HF122, and HN53HG120 — confirm your existing part number or unit data plate coil voltage and pole configuration before ordering. Our fitment team is available to verify compatibility prior to purchase. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50ZZ105610 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50ZZ105610 | National HVAC Parts. 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 C4850C50ZZ105610 | National HVAC Parts?
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?
