OEM Carrier 2-Pole Contactor for Model C4850C50AK06011 Packaged Unit

This is the factory-specified OEM replacement contactor for the Carrier C4850C50AK06011 packaged unit. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes its poles to send 240V power to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system will not turn on at all, hums without starting, or refuses to shut off. Pitting, burning, or welded contacts are telltale signs this part needs immediate replacement. Replaces OEM part numbers HN53CB115 and HN53HF122.

  • Specs: 2-pole design | 24V AC coil voltage | Factory-rated amperage for Carrier C4850C50AK06011 | NEMA-standard screw terminal configuration for straightforward wiring
  • OEM vs Generic: This OEM contactor is built to Carrier's exact coil pull-in voltage and contact amp rating. Aftermarket substitutes frequently use lower-grade silver-alloy contacts that pit and weld prematurely, especially under the high inrush loads of a 5-ton compressor.
  • Install Difficulty: 2/5 — Shut off power at the disconnect and breaker 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 to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse — get your system running fast.

Compatibility: Designed specifically for the Carrier C4850C50AK06011 packaged gas/electric unit. Please verify coil voltage (24V) and pole configuration on your unit's data plate or wiring diagram before ordering. Cross-references OEM part numbers HN53CB115 and HN53HF122. Our parts specialists are available to confirm fitment before you buy — don't guess on a critical switching component.

Frequently Asked Questions

Does this Contactor fit my Carrier C4850C50AK06011 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C4850C50AK06011 | 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 C4850C50AK06011 | 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?
