OEM Carrier Contactor 2-Pole 24V Coil for Model C4850C50ZG055900

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C4850C50ZG055900 packaged or split-system unit. The contactor acts as the primary electrical switch that connects line voltage to the compressor and condenser fan motor when your thermostat calls for cooling. A failed contactor is one of the most common causes of an air conditioner that hums, clicks, but refuses to start — or one that simply does nothing at all when the thermostat calls for cooling. Pitted or burned contacts, a weak coil, or contacts that weld shut are all signs it's time to replace.

  • Specs: 2-pole configuration | 24V coil voltage | 30–40A rated contacts | Direct OEM replacement — no modifications required. Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120.
  • OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips rated for full load amperage. Generic aftermarket units often use lower-grade alloys that pit and fail prematurely, especially under high-cycling summer conditions.
  • Install Difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. 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 against defects in materials and workmanship. Orders placed before 3PM ET ship same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier C4850C50ZG055900. This contactor supersedes OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — all three are covered by this single listing. Confirm coil voltage and pole configuration on your unit's data plate before ordering. Our fitment specialists are available to verify compatibility before you buy.

Frequently Asked Questions

How do I replace the contactor on my Carrier C4850C50ZG055900 — 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.
