OEM Carrier 3-Pole Contactor 40A 208–240V for Model YAC48110YAC103AT

This OEM Carrier contactor is the factory-specified replacement for the Carrier YAC48110YAC103AT packaged HVAC unit. The contactor is the high-voltage relay that closes the power circuit to the compressor and condenser fan motor every time your thermostat calls for cooling. When it fails — due to pitted contacts, a welded coil, or burned terminals — the system either won't turn on at all, runs continuously without shutting off, or trips the breaker on startup. Replacing this contactor is one of the most common and cost-effective HVAC service repairs.

  • Specs: 3-pole | 40A FLA / 160A LRA | Coil Voltage: 208–240V (HN53CD208) / 24V (HN53CD025) | 50/60 Hz | Screw terminal connections | Factory-matched Carrier OEM tolerances
  • OEM vs Generic: OEM contactors use silver-alloy contacts rated for thousands of switching cycles. Generic aftermarket units frequently use inferior contact materials that arc, pit, and weld shut prematurely — risking compressor damage and callbacks.
  • Install difficulty: 3/5 — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera/phone to photograph wiring before removal. Verify coil voltage on your unit's data plate matches the part number selected (208–240V = HN53CD208; 24V = HN53CD025).
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM replacement for Carrier model YAC48110YAC103AT. Two OEM part numbers cover this application — confirm coil voltage from your unit's data plate or wiring diagram before ordering. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy — reach out before placing your order.

Frequently Asked Questions

Does this Contactor fit my Carrier YAC48110YAC103AT?
Yes. This is the factory-specified OEM contactor for the Carrier YAC48110YAC103AT. 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 YAC48110YAC103AT?
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?
