OEM Carrier Contactor CP50P550P507021CP for Model CP50P550P507021CP

This authentic OEM Carrier contactor is the switching relay that energizes the compressor and outdoor fan motor in your Carrier condensing unit each time the thermostat signals for cooling. Manufactured to exact factory standards, it is fully compatible with Carrier model CP50P550P507021CP, providing the correct coil voltage, contact ratings, and mounting dimensions for a true drop-in replacement. Pitted or stuck contacts are a leading cause of no-cool calls, humming, and short cycling, and this genuine part restores dependable starts while shielding the compressor from harmful voltage drop. Replacement is a moderate job suited to a confident DIYer and simple for a pro: disconnect power at the outdoor breaker, photograph the wiring, transfer leads one at a time, then fasten the new contactor in place. OEM construction means tighter tolerances and longer life than economy alternatives. Every order placed before 3PM CST ships the same day, so cooling is restored quickly. Our HVAC specialists are available to confirm fitment for your exact unit before purchase.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P550P507021CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P550P507021CP. 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 CP50P550P507021CP?
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.
