OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P550P507010CP

This is the factory OEM replacement contactor for the Carrier CP50P550P507010CP packaged unit, sold under OEM part number HN53CD115. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a stuck plunger, or burned coil — the system will appear to call for cooling but the compressor and outdoor fan will not energize, leaving your space uncooled.

  • Specs: 2-pole configuration | 24V AC coil | High-amperage contacts rated for compressor loads | Direct factory-matched replacement for OEM part number HN53CD115
  • OEM vs Generic: OEM contactors feature precision contact surfaces and coil windings built to Carrier's exact specifications. Generic alternatives frequently exhibit premature contact pitting and coil burnout, leading to repeat failures — especially under high-cycle commercial and packaged unit conditions.
  • Install Difficulty: 3/5 — Always disconnect power at the main disconnect before servicing. Tools required: flathead and Phillips screwdrivers, needle-nose pliers, multimeter for voltage verification, and electrical tape. Photograph all wiring connections before removal. Line voltage is present in this enclosure — use proper PPE.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3PM EST ship same business day from our stocked warehouse.

Compatibility: Designed specifically for the Carrier CP50P550P507010CP packaged unit. Always verify the coil voltage (24V) and pole configuration on your unit's wiring diagram and data plate before ordering. The CP50 series is a Carrier commercial packaged gas/electric rooftop unit — confirm your existing contactor's amperage rating matches this replacement. Have your model and serial number ready, and our HVAC parts specialists are available to confirm fitment before you order. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P550P507010CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P550P507010CP. 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 CP50P550P507010CP?
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?
