OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P550P504020CP

This OEM replacement contactor is the factory-specified part for the Carrier CP50P550P504020CP packaged unit. The contactor is a high-voltage relay controlled by your 24V thermostat signal — when the thermostat calls for cooling, the contactor closes its poles to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system stops responding to thermostat calls entirely, or causes intermittent no-cool conditions, chattering, or welded contacts that prevent the system from shutting off.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier CP50 series | OEM part number HN53CD115 | Screw-terminal design for secure wiring connections
  • OEM vs Generic: This OEM contactor is manufactured to exact Carrier factory specifications, including contact material grade and coil pull-in voltage tolerance. Generic contactors frequently use lower-grade contact tips that arc, pit, and fail prematurely under compressor start-load conditions.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Contactor terminals carry line voltage — exercise full lockout/tagout precautions.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model CP50P550P504020CP packaged units using OEM part number HN53CD115. Always verify coil voltage (24V) and pole configuration against your unit's wiring diagram and data plate before ordering. Our HVAC parts specialists are available to confirm fitment — call or chat before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P550P504020CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P550P504020CP. 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 CP50P550P504020CP?
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?
