OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C48AY06051

This OEM Carrier contactor is the factory-specified high-voltage relay for the Carrier C4850C48AY06051 packaged unit. The contactor acts as the primary switching device that energizes the compressor and condenser fan motor when the thermostat calls for cooling. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — the unit either won't start at all, runs continuously without cycling off, or trips the breaker. Replacing a failed contactor restores reliable switching and protects downstream components like the compressor from voltage irregularities.

  • Specs: 2-Pole configuration | 24V control coil | 30–40A load rating | Factory-matched contact material and coil resistance | Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120
  • OEM vs Generic: OEM Carrier contactors use silver-alloy contact tips rated for the exact switching loads of this unit. Generic contactors often use lower-grade contact material that pits faster under repeated cycling, reducing service life by 30–50% in high-run-time climates.
  • Install difficulty: 2/5 — Disconnect power at the disconnect box and confirm zero voltage with a multimeter before touching any terminals. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting — line, load, and coil terminals must be reconnected correctly.
  • Warranty: 1-year OEM factory warranty. Orders placed before 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier C4850C48AY06051 4-ton packaged unit. This listing covers three superseded OEM part numbers — HN53CB115, HN53HF122, and HN53HG120 — all of which are direct replacements for this application. Verify pole count and coil voltage on your unit's data plate before ordering. Our parts specialists are available to confirm fitment at no charge.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48AY06051?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48AY06051. 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 C4850C48AY06051?
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?
