OEM Carrier Contactor Replacement for Model LC748LCCSRMYX2100

Get your system cooling again with this genuine OEM Carrier contactor, the switch that delivers power to the compressor and condenser fan motor on every cooling call. Engineered as a direct-fit replacement for the Carrier LC748LCCSRMYX2100, it matches the factory coil voltage and contact amperage so the unit energizes cleanly, without the chatter, arcing, or short cycling that shortens equipment life. Worn or welded contactors are one of the top causes of a unit that hums but won't start, and this low-cost part usually brings a stalled system back in just minutes. The replacement is an approachable DIY task: turn off power at the disconnect, take a photo of the existing wiring, transfer each lead to the corresponding terminal, and bolt the new contactor in place. Confirm the line voltage matches before restoring power. Factory-spec Carrier components protect compressor warranties and last far longer than bargain aftermarket switches. In stock and shipping same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model LC748LCCSRMYX2100?
Yes. This is the factory-specified OEM contactor for the Carrier Model LC748LCCSRMYX2100. 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 LC748LCCSRMYX2100?
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?
