OEM Carrier 2-Pole Contactor 24V Coil for Model C50A503562

This OEM contactor is the factory-specified high-voltage relay replacement for the Carrier C50A503562 commercial packaged unit. The contactor acts as the primary switching device that connects line-voltage power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When the contactor fails — through worn contact points, a burned coil, or a stuck plunger — the system will either refuse to start entirely, fail to shut off, or run erratically. Replaces OEM part numbers HN53CB115, HN53CD115, and HN53HF122.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30A contact rating | Factory-matched contact material and coil resistance for reliable pull-in and drop-out
  • OEM vs Generic: OEM contactors use silver-alloy contact tips engineered to factory arc-resistance specifications. Generic contactors frequently use inferior contact alloys that pit and weld prematurely, leading to compressor damage and repeat failures within a single season.
  • Install difficulty: 2/5 — Always disconnect power at both the disconnect box and the breaker panel before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil voltage before reinstalling panels. Photograph all wiring terminals before disconnecting leads.
  • Warranty: 1-year OEM factory warranty. Orders placed before our daily cutoff ship the same business day from our climate-controlled warehouse.

Compatibility: Engineered for the Carrier C50A503562 commercial packaged rooftop unit. Cross-references OEM part numbers HN53CB115, HN53CD115, and HN53HF122 — all three part numbers are superseded by this single current-production replacement. Verify your unit's data plate coil voltage and pole configuration before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A503562 — Ships Today?
Yes. This is the factory-specified OEM contactor for the Carrier C50A503562 — Ships Today. 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 C50A503562 — Ships Today?
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.
