OEM Carrier Contactor Replacement Part for Model LC748LCCSRMP2100

This genuine OEM Carrier contactor is the factory-specified switching component for the LC748LCCSRMP2100 condensing unit. The contactor energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling, using a low-voltage coil to close heavy-duty line-voltage contacts. Worn, pitted, or chattering contacts are a leading cause of no-cool service calls, hard starts, and burnt control wiring. Installing this exact-fit replacement restores reliable, quiet engagement and protects the rest of your system from voltage-related damage. Because it matches Carrier's original coil voltage, contact rating, and mounting footprint, it drops straight into the LC748LCCSRMP2100 with no rewiring or bracket modification. Installation is rated easy for a qualified technician and typically takes 15 to 20 minutes: disconnect power, photograph and transfer the wires, swap the part, and restore power. Always confirm power is off before servicing. We stock this contactor in our warehouse and ship same-day on all orders placed before 3PM CST, so your repair stays on schedule.

Frequently Asked Questions

Does this Contactor fit my Carrier Model LC748LCCSRMP2100?
Yes. This is the factory-specified OEM contactor for the Carrier Model LC748LCCSRMP2100. 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 LC748LCCSRMP2100?
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?
