OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50AW06011

This is the factory OEM replacement contactor for the Carrier C4850C50AW06011 packaged unit. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will either refuse to start entirely, run continuously without shutting off, or trip the breaker. OEM part numbers HN53CB115 and HN53HF122 are direct factory-specified replacements.

  • Specs: 2-pole configuration | 24V control coil | 40A rated contacts | Factory-matched contact material for R-410A system loads
  • OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips that resist pitting and arcing far longer than generic brass contacts. Choosing OEM protects your compressor investment and reduces callback risk.
  • Install difficulty: 2/5 — Always disconnect power at both the disconnect box and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before removal. Coil wires and line/load lugs must be transferred exactly.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed specifically for the Carrier C4850C50AW06011 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our fitment team is available to verify compatibility — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AW06011 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AW06011 | 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 C4850C50AW06011 | 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?
