OEM Carrier Contactor 2-Pole 24V Coil for Model C4850C50AW03561

This is the factory OEM replacement contactor (part# HN53CB115) for the Carrier C4850C50AW03561 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat control board and closes the circuit to energize the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will not cool, the compressor won't start, or the unit may run continuously without shutting off.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier C4850C50AW03561 | OEM part number HN53CB115 | Direct drop-in replacement — no wiring modifications required
  • OEM vs Generic: OEM contactors feature factory-grade silver-alloy contact tips rated to exact amperage draw of your compressor. Generic contactors often use lower-grade contacts that pit and arc faster, leading to repeat failures within one to two seasons.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Transfer wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed specifically for the Carrier C4850C50AW03561 packaged unit. Verify coil voltage (24V) and pole count on your existing contactor's label before ordering to confirm fitment. If you are unsure whether this part matches your unit, our HVAC parts specialists are available to verify compatibility before you purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AW03561 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AW03561 | 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 C4850C50AW03561 | 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?
