OEM Carrier 2-Pole Contactor 24V Coil for Model C50A502722

This OEM replacement contactor is the factory-specified part for the Carrier C50A502722 packaged unit. The contactor functions as the primary high-voltage relay in your HVAC system, receiving a low-voltage signal (24V) from the thermostat or control board and switching the high-voltage circuit that powers the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will appear completely unresponsive, fail to cool, or may run continuously without cycling off.

  • Specs: 2-pole configuration | 24V coil voltage | Heavy-duty contact rating | OEM part numbers HN53CB115 / HN53CD115 | Factory-matched for Carrier C50A502722
  • OEM vs Generic: OEM contactors use precision-milled silver-alloy contacts rated for thousands of switching cycles. Generic aftermarket units often use lower-grade contact materials that pit and corrode faster, leading to repeat failures 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 wire connections before removing the old contactor. Terminals are line-voltage — exercise extreme caution.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model C50A502722 packaged unit. OEM part numbers HN53CB115 and HN53CD115 are both covered by this listing — verify coil voltage and pole count against your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before you buy — contact us today and get your system back up and running fast.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A502722?
Yes. This is the factory-specified OEM contactor for the Carrier C50A502722. 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 C50A502722?
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?
