OEM Carrier 2-Pole Contactor 24V Coil for Model C50A505062

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C50A505062 packaged unit. The contactor acts as the primary electrical switch that energizes the compressor and condenser fan motor when your thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burned coil, or stuck contacts — your system may hum without starting, run continuously without cycling off, or simply refuse to turn on altogether. OEM part numbers covered: HN53CB115, HN53CD115, HN53HF122.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage matched to C50A505062 | Silver-alloy contact points for reduced arcing and extended service life
  • OEM vs Generic: OEM contactors from Carrier use precision-rated coil windings and contact alloys that meet exact factory specifications. Generic contactors often use lower-grade contact materials that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box 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 high-voltage wiring before removing any terminals to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our warehouse.

Compatibility: Engineered for the Carrier C50A505062 commercial packaged unit. This listing covers OEM part numbers HN53CB115, HN53CD115, and HN53HF122 — all factory-authorized replacements for this application. Confirm coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to verify fitment prior to purchase — don't guess on a contactor replacement.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A505062?
Yes. This is the factory-specified OEM contactor for the Carrier C50A505062. 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 C50A505062?
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?
