OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50ZZ105110

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C4850C50ZZ105110 packaged unit. The contactor acts as the primary switching device that connects and disconnects line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. A failed contactor is one of the most common causes of a system that simply won't turn on — symptoms include a humming sound with no compressor start, burnt or pitted contacts visible on inspection, or a unit that runs continuously without cycling off. Replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120.

  • Specs: 2-Pole configuration | 24V AC coil voltage | Heavy-duty contact rating matched to factory specifications | Direct drop-in replacement with identical terminal layout
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contacts rated to Carrier's exact load specifications. Generic contactors often use lower-grade contact material that pits faster under high inrush current, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always shut off power at both the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Verify coil voltage with your multimeter prior to installation.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier C4850C50ZZ105110 packaged unit and directly replaces OEM part numbers HN53CB115, HN53HF122, and HN53HG120. Confirm coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — contact us anytime.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50ZZ105110 — Ships Today?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50ZZ105110 — Ships Today. 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 C4850C50ZZ105110 — Ships Today?
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.
