OEM Carrier 2-Pole Contactor 24V Coil for Model C50A502552

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C50A502552 packaged unit. The contactor acts as the primary switching device that routes 240V power to the compressor and condenser fan motor whenever the thermostat calls for cooling. A failing contactor is one of the most common causes of an AC system that hums but won't start, trips breakers repeatedly, or simply produces no cooling response at all. OEM part numbers covered: HN53CB115, HN53CD115, and HN53HF122.

  • Specs: 2-pole configuration | 24V AC coil voltage | High-amperage contact rating | Factory-matched contact gap and spring tension for reliable pull-in and drop-out
  • OEM vs Generic: OEM contactors use silver-alloy contact tips that resist pitting and arcing far longer than generic brass contacts. Burnt or pitted contacts are the #1 reason contactors fail prematurely — don't accelerate that cycle with an undersized aftermarket part.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the unit. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Transfer one wire at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier C50A502552 commercial packaged unit. Cross-references OEM part numbers HN53CB115, HN53CD115, and HN53HF122 — confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our parts specialists are available to verify fitment. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A502552?
Yes. This is the factory-specified OEM contactor for the Carrier C50A502552. 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 C50A502552?
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?
