OEM Carrier Contactor CP50P550P507011CP for Model CP50P550P507011CP

Get your Carrier unit switching reliably again with this authentic OEM contactor, the relay that closes the line-voltage circuit to the compressor and outdoor fan when the thermostat demands cooling. Engineered to factory standards, it is fully compatible with Carrier model CP50P550P507011CP, matching the original coil voltage, amperage, and bolt pattern for a precise drop-in replacement. Worn contacts cause humming, intermittent operation, or a complete no-start, and this genuine part eliminates those issues while protecting the compressor from voltage drop and excess heat. Replacement is a moderate DIY task: shut off power at the disconnect, take a photo of the existing wiring, transfer leads one terminal at a time, and mount the new contactor securely before restoring power. Experienced homeowners complete it quickly, and it is a basic repair for HVAC pros. OEM build quality ensures longer contact life than generic alternatives. Place your order before 3PM CST and it ships the same day, getting your home cool again without a long wait. Our parts team is ready to verify fitment.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P550P507011CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P550P507011CP. 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 CP50P550P507011CP?
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.
