OEM Carrier Contactor 2-Pole 24V Coil for Model C4850C50ZN070200

This OEM contactor is the factory-specified high-voltage relay for the Carrier C4850C50ZN070200 packaged unit. The contactor acts as the primary switching device that closes the high-voltage circuit to energize the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails, the most common symptoms include the system not turning on despite the thermostat calling for cooling, visible pitting or burning on the contact points, or a chattering/buzzing noise from the disconnect area. Replaces OEM part numbers HN53CB115 and HN53HF122.

  • Specs: 2-Pole configuration | 24V coil voltage | Factory-matched contact rating | Direct OEM replacement for Carrier packaged units — no modifications required
  • OEM vs Generic: OEM contactors use silver-alloy contact points rated for thousands of switching cycles. Generic contactors frequently use inferior contact materials that pit and weld prematurely, causing compressor lockouts and costly callbacks.
  • Install Difficulty: 3/5 — Always disconnect power at the main disconnect and verify zero voltage with a multimeter before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered for the Carrier C4850C50ZN070200 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Verify coil voltage and pole configuration on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — same-day shipping available on all in-stock OEM contactors.

How do I replace the contactor on my Carrier C4850C50ZN070200 — Ships Today?
Difficulty: Medium (30–45 min)

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.
