OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P550P503510CP

This OEM contactor is the factory-specified high-voltage relay for the Carrier CP50P550P503510CP packaged unit. The contactor acts as the main switching component in the outdoor unit's control circuit — when the thermostat calls for cooling, a 24V signal energizes the coil, closing the contacts and delivering high-voltage power to the compressor and condenser fan motor. A failed contactor typically results in the air conditioner not turning on at all, or intermittent compressor dropout during a cooling cycle. Pitted or burned contacts are the most common cause of failure and are a safety concern if left unaddressed.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage matched to OEM spec | OEM part number HN53CD115 | Designed for Carrier packaged unit applications
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated to factory amperage specifications. Generic alternatives frequently use lower-grade contacts that pit faster under load, leading to premature re-failure and potential compressor damage.
  • Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting — incorrect wiring can damage the control board or compressor.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered specifically for Carrier model CP50P550P503510CP packaged units. Cross-reference OEM part number HN53CD115 against your unit's data plate to confirm coil voltage and pole configuration before ordering. Our parts specialists are available to verify fitment — reach out before you order if you have any questions. Orders placed by 3PM ship the same business day.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P550P503510CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P550P503510CP. 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 CP50P550P503510CP?
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.
