OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50AK06091

This OEM replacement contactor is the factory-specified part for the Carrier C4850C50AK06091 packaged unit. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from the thermostat and switches line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — your system may not turn on at all, run continuously without cycling off, or trip the breaker repeatedly. OEM part numbers covered: HN53CB115, HN53HF122, HN53HG120.

  • Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty contact rating | Factory-matched coil pull-in voltage for reliable switching
  • OEM vs Generic: OEM contactors feature silver-alloy contacts that resist pitting and arcing far longer than generic alternatives. A failed generic contactor can weld shut, leaving your system running uncontrolled or damaging the compressor — OEM is the safer long-term investment.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or tape. Photograph all wiring before removing any terminals. Discharge any capacitors nearby before working in the electrical compartment.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed for the Carrier C4850C50AK06091 packaged unit. This listing covers OEM part numbers HN53CB115, HN53HF122, and HN53HG120 — all factory-authorized replacements for this model. Verify your existing contactor's pole count and coil voltage against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy. In stock — order now and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AK06091 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AK06091 | 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 C4850C50AK06091 | 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.
