OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P450P405020CP

This is the factory OEM replacement contactor for the Carrier CP50P450P405020CP packaged unit. The contactor is the high-voltage relay that receives a 24V signal from your thermostat or control board and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your system will either not respond to a call for cooling at all, or will run continuously without cycling off. OEM part number HN53CD115 ensures a factory-precise fit and reliable operation.

  • Specs: 2-pole configuration | 24V control coil | Factory-rated amperage for Carrier CP50P450P405020CP | Direct OEM replacement part number HN53CD115
  • OEM vs Generic: OEM contactors feature factory-spec contact material and coil windings, ensuring proper pull-in voltage and long service life. Generic contactors may have inconsistent contact ratings that lead to premature pitting and repeat failures.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Line voltage terminals remain energized until the disconnect is pulled — treat all wiring as live until confirmed otherwise.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: This contactor is the direct OEM replacement for Carrier model CP50P450P405020CP packaged units. Always verify the pole count, coil voltage, and amperage rating on your existing unit's data plate and original contactor before ordering to confirm fitment. Have your model and serial number ready — our parts specialists are available to verify compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P450P405020CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P450P405020CP. 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 CP50P450P405020CP?
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.
