OEM Carrier Contactor Replacement for Model LC748LCCSRMYX2500

This genuine OEM Carrier contactor is the power switch that engages your compressor and condenser fan motor each time a cooling cycle starts. Manufactured as a direct-fit replacement for the Carrier LC748LCCSRMYX2500, it carries the correct coil voltage and contact rating so the unit pulls in firmly without buzzing, arcing, or short cycling that wears out other components. A burnt, pitted, or stuck contactor is among the most frequent reasons a system hums but won't run, and this affordable swap typically restores full cooling in minutes. The repair is friendly to most DIY homeowners: shut off power at the outdoor disconnect, photograph the wiring for reference, move each lead to the matching terminal on the new switch, and secure it. Double-check that line voltage matches before re-energizing. Sticking with factory-spec Carrier parts protects compressor warranties and outperforms low-cost generic switches over the long haul. In stock and ready to ship same-day when ordered before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model LC748LCCSRMYX2500?
Yes. This is the factory-specified OEM contactor for the Carrier Model LC748LCCSRMYX2500. 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 LC748LCCSRMYX2500?
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?
