OEM Carrier 2-Pole Contactor HN52TC040 for Model LC748LCCSRMYX2601

This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier LC748LCCSRMYX2601 condensing unit. The contactor is the primary high-voltage switching relay in your system — it receives a 24V signal from the thermostat and closes to send line voltage (typically 240V) to the compressor and condenser fan motor. When the contactor fails, symptoms include an air conditioner that won't turn on at all, a unit that hums but never starts, or one that trips the breaker repeatedly. Pitted or burnt contacts are the most common cause of failure and are easily visible on inspection.

  • Specs: 2-Pole configuration | 24V AC coil voltage | Rated for high-amperage compressor loads | Direct OEM replacement per Carrier part number HN52TC040
  • OEM vs Generic: This OEM contactor uses factory-spec contact materials and coil windings, ensuring proper pull-in voltage and long contact life. Generic contactors often use inferior contact alloys that pit faster under load, leading to repeat failures within one season.
  • Install difficulty: 3/5 — ALWAYS shut off power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or tape. Photograph all wiring connections before removing the old contactor. Verify coil voltage with a multimeter before condemning the part.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our NationalHVACParts.com warehouse when ordered before 3PM local time.

Compatibility: Designed as a direct OEM replacement for the Carrier LC748LCCSRMYX2601 condensing unit. Always confirm the coil voltage and pole configuration printed on your existing contactor's label before ordering. If you have questions about fitment, our HVAC parts specialists verify compatibility before you purchase — no guesswork required. Order today and get your system back up and running fast.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRMYX2601?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRMYX2601. 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 LC748LCCSRMYX2601?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
