OEM Carrier 2-Pole Contactor 24V Coil for Model C50A402722

This OEM replacement contactor is the factory-specified part for the Carrier C50A402722 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 supplies line voltage to the compressor and condenser fan motor. A failed or pitted contactor is one of the most common causes of an air conditioning system that simply won't turn on, hums at startup, or trips the breaker repeatedly. OEM part numbers HN53CB115 and HN53CD115 are both covered by this listing.

  • Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty silver-alloy contacts | Rated for high-cycle commercial and residential packaged unit applications
  • OEM vs Generic: OEM contactors (HN53CB115 / HN53CD115) use factory-grade contact material and spring tension. Generic units often suffer from premature pitting, arcing, and coil burnout — resulting in repeat failures within a single season.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: This contactor is engineered specifically for the Carrier C50A402722 packaged unit. Cross-reference your existing part number against HN53CB115 or HN53CD115 and verify coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists confirm fitment before your order ships — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A402722?
Yes. This is the factory-specified OEM contactor for the Carrier C50A402722. 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 C50A402722?
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?
