OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50AW05151

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C4850C50AW05151 packaged unit. The contactor acts as the primary electrical switch that powers the compressor and condenser fan motor when your thermostat calls for cooling. A failed contactor is one of the most common reasons an AC system hums but won't start, trips the breaker repeatedly, or simply refuses to respond to a cooling demand. Burned or pitted contacts cause intermittent operation, overheating, and compressor damage if left unaddressed.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage for Carrier C4850C50AW05151 | Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120
  • OEM vs Generic: This OEM contactor uses silver-alloy contact points engineered to Carrier's exact load specs. Aftermarket contactors frequently use lower-grade contacts that arc and pit faster, increasing the risk of compressor failure and nuisance lockouts.
  • Install difficulty: 2/5 — Always shut off power at both the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The contactor slides or snaps into the control panel rail and terminals are screw-type for straightforward reconnection.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Engineered for the Carrier C4850C50AW05151 packaged unit. This listing covers three OEM part numbers — HN53CB115, HN53HF122, and HN53HG120 — which are factory cross-references for this platform. Verify your unit's data plate voltage and amperage ratings before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AW05151 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AW05151 | 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 C4850C50AW05151 | 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?
