OEM Carrier Replacement Contactor for Model CP50P550P505021CP

This OEM Carrier contactor is the genuine electromagnetic switch that controls power to your condensing unit's compressor and fan motor, closing the high-voltage circuit every time your system calls for cooling. Manufactured to factory specifications for Carrier model CP50P550P505021CP, it offers an exact, direct-fit replacement with no rewiring needed. Pitted, burned, or stuck contacts are a leading cause of an outdoor unit that buzzes but won't start, or that keeps running after the thermostat is satisfied. Swapping in a fresh contactor restores clean contact closure and shields your compressor from damaging chatter and voltage loss. The job is beginner-friendly for most homeowners, taking roughly 15 to 20 minutes with basic tools — just be sure to cut power at the disconnect and breaker first. Installing genuine OEM hardware guarantees the correct amperage rating, coil voltage, and terminal configuration. We keep this part in stock and ship same-day on every order placed before 3PM CST, getting your cooling system back online quickly.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P550P505021CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P550P505021CP. 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 CP50P550P505021CP?
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.
