OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50ZG035600

This is the OEM factory-specified contactor (part number HN53CB115) for the Carrier C4850C50ZG035600 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes to send line voltage to the compressor and condenser fan motor. When it fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the unit will appear completely unresponsive, hum without starting, or fail to restart after a cycle. Replacing the contactor is one of the most common and cost-effective HVAC repairs available.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A contact rating | Factory-matched to Carrier packaged unit electrical specifications | OEM part number HN53CB115
  • OEM vs Generic: This OEM contactor uses silver-alloy contacts rated for the exact switching load of your Carrier packaged system. Generic contactors may use lower-grade contact materials that pit faster, leading to repeat failures and potential compressor damage.
  • Install Difficulty: 2/5 — Disconnect power at both the disconnect box and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire connections before removing the old contactor. Match wire terminals one-for-one on the replacement.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier C4850C50ZG035600 packaged unit. Always verify coil voltage and pole configuration against your unit's wiring diagram and data plate before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions. Order today for same-day shipping.

How do I replace the contactor on my Carrier C4850C50ZG035600 — 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.
