OEM Carrier 2-Pole Contactor for Model C4850C50AW02551

This OEM contactor is the factory-specified high-voltage switching relay for the Carrier C4850C50AW02551 packaged unit. The contactor acts as the primary electrical switch that sends line voltage to the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burnt coil, or contact welding — the unit will either fail to start entirely, short-cycle unexpectedly, or run continuously without responding to thermostat signals. Replaces OEM part numbers HN53CB115 and HN53HF122.

  • Specs: 2-Pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier C4850C50AW02551 | Direct OEM replacement, no wiring modifications required
  • OEM vs Generic: OEM contactors use silver-alloy contact tips engineered to Carrier's exact load specifications. Generic contactors often use lower-grade contacts that pit faster under high-cycle conditions, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Requires shutting off power at both the disconnect and breaker panel before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, needle-nose pliers, wire labels or tape. Always photo-document wiring before disconnecting. Discharge any capacitors in the unit before working near electrical components.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered for Carrier model C4850C50AW02551. Cross-references OEM part numbers HN53CB115 and HN53HF122. Confirm coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence.

Frequently Asked Questions

How do I replace the contactor on my Carrier C4850C50AW02551 — 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.
