OEM Carrier 2-Pole Contactor 24V Coil for Model CP50P550P504011CP

This OEM contactor is the factory-specified replacement for the Carrier CP50P550P504011CP packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes and sends line voltage to the compressor and condenser fan motor. When it fails, the most common symptoms are an AC system that won't turn on at all, a compressor that won't energize despite the thermostat calling for cooling, or audible chattering and pitting on the contactor contacts from normal wear and arcing over time.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage to match Carrier CP50P550P504011CP specifications | OEM Part Number HN53CD115
  • OEM vs Generic: This OEM contactor is built to exact Carrier factory specifications, ensuring proper coil pull-in voltage, contact rating, and long-term reliability. Generic contactors may use lower-grade contacts that pit and fail prematurely, risking compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier CP50P550P504011CP commercial packaged unit. Verify OEM part number HN53CD115 and coil voltage on your unit's data plate before ordering. If you need fitment confirmation, our HVAC parts specialists are available to verify compatibility before you purchase — same-day shipping available on all in-stock OEM parts.

Frequently Asked Questions

Does this Contactor fit my Carrier CP50P550P504011CP?
Yes. This is the factory-specified OEM contactor for the Carrier CP50P550P504011CP. 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 CP50P550P504011CP?
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?
