OEM Carrier Contactor CP50P450P405511CP for Model CP50P450P405511CP

This genuine OEM Carrier contactor is the electrically operated switch that sends power to your compressor and condenser fan motor each time the thermostat calls for cooling. Engineered to factory specification for Carrier model CP50P450P405511CP, it provides the exact coil voltage and contact amperage rating your system needs, preventing the chatter, contact pitting, and weld-shut failures that cause generic substitutes to fail prematurely. Replacing a worn contactor resolves one of the most common no-cool conditions and protects your compressor from damaging electrical arcing. This is an intermediate-level repair ideal for a qualified HVAC technician: turn off power at the disconnect, move the line, load, and coil wires across one terminal at a time, and mount the new contactor to its bracket—most installs finish in under 30 minutes. Always confirm the unit is de-energized before handling any wiring. Order before 3PM CST and your contactor ships the same business day from our US warehouse, getting your cooling system back online with minimal downtime.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P450P405511CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P450P405511CP. 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 CP50P450P405511CP?
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.
