OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C48AY06011

This OEM contactor is the factory-specified replacement for the Carrier C4850C48AY06011 packaged or split-system unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the stat calls for cooling, the contactor closes and sends line voltage to the compressor and condenser fan motor. When the contactor fails, pitted or burned contacts cause the system to hum without starting, fail to energize at all, or run continuously without shutting off. Replaces OEM part numbers HN53CB115 and HN53HF122.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Direct OEM replacement — factory-matched contact material and coil pull-in voltage
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic contactors often use lower-grade alloys that pit and weld shut prematurely, causing compressors to run continuously or fail to start.
  • Install difficulty: 2/5 — Disconnect all power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, multimeter, and needle-nose pliers. Photograph all wiring before removing the old contactor. Line voltage terminals are live until power is fully disconnected — verify with a multimeter before touching.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model C4850C48AY06011. Verify pole count and coil voltage on your unit's data plate or wiring diagram before ordering. Supersedes part numbers HN53CB115 and HN53HF122. Our fitment team is available to confirm compatibility before you order — contact us with your model and serial number for a verified match. Order today and receive same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48AY06011?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48AY06011. 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 C4850C48AY06011?
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?
