OEM Carrier Contactor C48A403051 for Model C48A403051

This genuine OEM Carrier contactor (C48A403051) is the core switching relay that energizes your compressor and condenser fan motor whenever the thermostat calls for cooling. Manufactured to Carrier's precise factory tolerances, it ensures reliable high-amperage switching, clean contact closure, and strong resistance to the pitting and burning that cause hard starts and system failures. It is an exact-fit replacement for Carrier model C48A403051, matching the original coil voltage and pole configuration for a true plug-and-play installation. Installing a fresh contactor cures buzzing, intermittent cooling, weak starts, and overheated terminals, restoring steady, dependable operation. The repair is moderate in difficulty for a trained HVAC technician: kill the power at the disconnect, transfer the wiring one lead at a time, mount the new unit, and reconnect — usually completed in under 30 minutes. We keep this part stocked and ship same-day on every order placed before 3PM CST to minimize your downtime. All Carrier OEM parts are brand-new, never reconditioned, and meet genuine factory quality standards for long, reliable service.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C48A403051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C48A403051. 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 C48A403051?
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?
