OEM Carrier 2-Pole Contactor 24V Coil for Model C50A406011

This OEM contactor is the factory-specified high-voltage relay for the Carrier C50A406011 commercial packaged unit. The contactor acts as the primary switching device that allows 240V power to reach the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will either fail to turn on entirely, run continuously without shutting off, or trip the breaker repeatedly. OEM part numbers HN53CB115, HN53CD115, and HN53HF122 are all factory-authorized replacements for this application.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30A rated | Single-phase load side | Direct OEM replacement matching factory contact gap and coil pull-in voltage
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic units frequently use lower-grade alloys that pit and arc prematurely, leading to repeat failures within a single cooling season.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify with a non-contact voltage tester before touching any terminals. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers. Photograph all wire connections before removal — line and load wires must return to the correct terminals.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier C50A406011 commercial packaged rooftop unit. Cross-reference OEM part numbers HN53CB115, HN53CD115, or HN53HF122 to confirm fitment. Always verify coil voltage and amperage ratings on your unit's data plate before ordering. Our parts specialists are available to confirm compatibility before you buy — order today and receive same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A406011 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C50A406011 | National HVAC Parts. 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 C50A406011 | National HVAC Parts?
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?
