OEM Carrier 2-Pole Contactor for Model C4850C50AW02051

This is the factory-specified OEM replacement contactor for the Carrier C4850C50AW02051 packaged unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat or control board and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will not cool, the compressor will not energize, or the unit may run continuously without cycling off. OEM part numbers HN53CB115 and HN53HF122 are the direct factory replacements for this model.

  • Specs: 2-Pole configuration | 24V coil voltage | Rated for standard residential and light-commercial amperage loads | Direct OEM fit for Carrier C4850C50AW02051 — no modifications required
  • OEM vs Generic: OEM contactors use factory-spec contact materials and coil windings that match the exact electrical load profile of your unit. Generic contactors may use lower-grade contact alloys that pit faster under high-cycle summer loads, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Requires disconnecting line voltage at the disconnect box and verifying zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, insulated gloves. Photograph all wiring connections before removal. Always confirm the capacitor is discharged before working in the panel.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier C4850C50AW02051 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Verify your unit's data plate coil voltage and pole configuration before ordering to ensure proper fitment. Need help confirming the right part?

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AW02051 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AW02051 | National HVAC Parts. 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 C4850C50AW02051 | National HVAC Parts?
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?
