OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50AK05161

This OEM contactor is the factory-specified replacement for the Carrier C4850C50AK05161 packaged unit. The contactor is the high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — you'll typically find the system completely unresponsive to cooling calls, or conversely, locked in the "on" position and unable to shut off. OEM part numbers covered by this listing include HN53CB115, HN53HF122, and HN53HG120, all factory-verified fits for this model.

  • Specs: 2-pole configuration | 24V AC coil voltage | Rated for high-amperage compressor loads | Direct factory replacement matching original wiring terminals and mounting footprint
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles under full load. Generic contactors often use inferior contact materials that pit and weld prematurely, causing compressor damage or nuisance lockouts within a single season.
  • Install difficulty: 3/5 — Requires disconnecting line voltage at the disconnect box and allowing capacitors to discharge fully before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and insulated gloves. Always photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before our same-day cutoff ship from our warehouse the same business day.

Compatibility: Designed specifically for the Carrier C4850C50AK05161 packaged unit. Cross-references OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Confirm coil voltage and pole count on your unit's data plate before ordering. Our fitment team is available to verify compatibility prior to purchase — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AK05161 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AK05161 | 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 C4850C50AK05161 | 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?
