OEM Carrier Contactor LC748LCCSRMY2101 for Model LC748LCCSRMY2101

This genuine OEM Carrier contactor is the factory-specified replacement for Carrier model LC748LCCSRMY2101 packaged HVAC units. The contactor serves as the main high-voltage switch that powers the compressor and condenser fan motor on a thermostat cooling call, with a low-voltage coil pulling the contacts closed. Burned, pitted, or sticking contacts commonly cause no-cool service calls, buzzing, and compressor hard starts, and replacing the part with the correct OEM contactor restores dependable switching while safeguarding downstream components. Built to the original coil voltage, pole configuration, and amp rating, it installs in the factory mounting position using the same terminal layout. Installation is straightforward for a trained technician: cut power at the disconnect, document the existing wiring, move each lead to the matching terminal, and confirm coil voltage before restoring power. Genuine OEM ensures correct ratings that generic contactors often miss, and helps protect your equipment warranty. Order before 3PM CST for same-day shipping from stock. National HVAC Parts carries authentic Carrier components with fair pricing and fast, reliable delivery to get your system cooling again.

Frequently Asked Questions

Does this Contactor fit my Carrier Model LC748LCCSRMY2101?
Yes. This is the factory-specified OEM contactor for the Carrier Model LC748LCCSRMY2101. 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 LC748LCCSRMY2101?
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?
