OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P450P406010CP

This OEM contactor is the factory-specified replacement for the Carrier CP50P450P406010CP packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to power the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burnt coil, or contacts welded shut — your system will either refuse to start, run continuously without shutting off, or trip the breaker repeatedly.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier CP50 series packaged units | OEM part number HN53CD115
  • OEM vs Generic: This OEM contactor is manufactured to exact Carrier factory specifications, ensuring proper coil pull-in voltage and contact rating. Generic contactors frequently 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 breaker panel before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Verify coil voltage with a multimeter before condemning the part.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock units ship the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier CP50P450P406010CP commercial packaged unit. The CP50 series designates a Carrier commercial rooftop/packaged platform — always cross-reference OEM part number HN53CD115 and verify coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — don't guess on a part this critical to compressor longevity.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P450P406010CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P450P406010CP. 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 CP50P450P406010CP?
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?
