OEM Carrier 2-Pole Contactor for Model C4850C48ZG055600

This OEM replacement contactor is the factory-specified high-voltage switching relay for the Carrier C4850C48ZG055600 packaged or split-system unit. The contactor receives a 24V signal from the thermostat or control board and closes its contacts to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contact points, a stuck plunger, or a failed coil — the outdoor unit will not energize at all, or may run continuously without shutting off. OEM part numbers HN53CB115 and HN53HF122 are direct factory replacements for this application.

  • Specs: 2-Pole configuration | 24V coil voltage | Rated for compressor and condenser fan load | Factory-matched contact rating for Carrier C4850C48ZG055600
  • OEM vs Generic: OEM contactors use silver-alloy contact tips that resist pitting and arcing far longer than generic alternatives. Generic contactors often use lower-grade alloys that degrade quickly under high-cycling conditions, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph existing wiring before removing any terminals. Transfer wires one at a time to the new contactor to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock units ship same business day from our warehouse.

Compatibility: Designed and factory-tested for the Carrier C4850C48ZG055600. Verify coil voltage (24V) and pole configuration against your unit's wiring diagram or data plate before ordering. Cross-reference OEM part numbers HN53CB115 or HN53HF122 to confirm fitment. Have questions about compatibility? Our HVAC parts specialists verify fitment before you order — contact us before purchasing.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C48ZG055600?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C48ZG055600. 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 C4850C48ZG055600?
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?
