OEM Carrier 2-Pole Contactor 24V Coil for Model C50A403562

This OEM replacement contactor is the factory-specified part for the Carrier C50A403562 packaged rooftop unit. The contactor is a high-voltage relay controlled by a low-voltage (24V) signal from the thermostat or control board. It switches line voltage to the compressor and condenser fan motor whenever a cooling call is made. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will not energize, leaving you with warm air or a completely unresponsive outdoor unit. Replaces OEM part numbers HN53CB115, HN53CD115, and HN53HF122.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier commercial rooftop applications | Silver-alloy contact tips for long service life and low resistance
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage, contact gap, and ampacity specifications. Aftermarket contactors frequently use lower-grade contact materials that arc, pit, and weld prematurely — leading to callbacks and compressor damage.
  • Install difficulty: 3/5 — Disconnect and lock out power at the disconnect box before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring before removing the old contactor. Verify coil voltage with a multimeter prior to replacement to rule out a control board fault.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier C50A403562 commercial packaged rooftop units. Cross-references OEM part numbers HN53CB115, HN53CD115, and HN53HF122. Always confirm coil voltage and pole configuration on your unit's wiring diagram or data plate before ordering. Our parts specialists are available to verify fitment — reach out before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier C50A403562?
Yes. This is the factory-specified OEM contactor for the Carrier C50A403562. 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 C50A403562?
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?
