OEM Carrier Contactor Replacement for Model LC748LCCSRMPX2500

This genuine OEM Carrier contactor is the electrically operated switch that energizes your unit's compressor and condenser fan motor each time a cooling cycle begins. Engineered as a direct-fit replacement for the Carrier LC748LCCSRMPX2500, it delivers reliable coil pull-in, clean contact closure, and the correct amperage rating your system was designed around, preventing chatter, short cycling, and burnt terminals. A worn or pitted contactor is one of the most common causes of a unit that hums but won't start, and swapping it restores dependable operation. Installation is an easy, do-it-yourself repair for most homeowners: shut off power at the disconnect, photograph the wiring, transfer the leads to the matching terminals, and secure the new contactor. Always confirm the line voltage matches before energizing. Using factory-spec Carrier components protects compressor warranties and avoids the premature failures common with generic substitutes. In stock and ships same-day when your order is placed before 3PM CST, so you can get cooling back fast.

Frequently Asked Questions

Does this Contactor fit my Carrier Model LC748LCCSRMPX2500?
Yes. This is the factory-specified OEM contactor for the Carrier Model LC748LCCSRMPX2500. 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 Model LC748LCCSRMPX2500?
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?
