OEM Carrier 3-Pole Contactor 24V 40A — HN53CD024 for Model YAC3680YAC107C

This OEM Carrier contactor (part number HN53CD024) is the factory-specified high-voltage relay for the Carrier YAC3680YAC107C packaged unit. The contactor acts as the primary switching device between your 24V thermostat control circuit and the high-voltage compressor and fan motor loads. When the thermostat calls for cooling, the 24V coil energizes and closes the contacts, sending line voltage to the compressor. A failed contactor is one of the most common reasons an air conditioner will not start — symptoms include a system that hums briefly then shuts off, a compressor that runs constantly without cycling, or a unit that shows no response at all when cooling is demanded.

  • Specs: 3-pole configuration | 24V AC coil voltage | 40A full-load amperage (FLA) | Max 600V | Screw-mount terminal connections | Factory-matched OEM replacement
  • OEM vs Generic: OEM contactors use factory-spec contact material and coil windings, ensuring proper pull-in voltage and contact life. Generic contactors can suffer from coil chatter, premature pitting, and welded contacts — all of which can damage your compressor.
  • Install difficulty: 3/5 — Requires disconnecting high-voltage power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, voltage tester. Always photograph all wiring before removal. Line voltage terminals must be treated with extreme caution even after disconnect.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse — order by 3 PM local time for same-day dispatch.

Compatibility: Engineered as a direct OEM replacement for Carrier model YAC3680YAC107C. Verify your existing contactor's pole count, coil voltage, and amperage rating on the data plate before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier YAC3680YAC107C?
Yes. This is the factory-specified OEM contactor for the Carrier YAC3680YAC107C. 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 YAC3680YAC107C?
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?
