OEM Carrier Contactor CP50P550P506021CP for Model CP50P550P506021CP

This genuine OEM Carrier contactor is the electromechanical switch responsible for energizing your compressor and condenser fan motor each time cooling is called for. Built to exact factory specifications, it is fully compatible with Carrier model CP50P550P506021CP, providing the correct coil voltage, contact ratings, and mounting dimensions for a seamless drop-in replacement. Pitted, welded, or chattering contacts lead to no-cool service calls, buzzing noises, and short cycling, and this OEM part restores crisp, dependable switching while protecting the compressor from harmful voltage drop. Installation is a moderate job: disconnect power at the outdoor breaker, photograph the wiring for reference, transfer each lead individually, and fasten the new contactor. Most confident DIYers complete the swap in under an hour, and it is routine for any technician. Choosing genuine Carrier parts ensures tighter tolerances and a longer service life than economy substitutes. Orders placed before 3PM CST ship the same day, so your system is back to cooling fast. Reach out to our HVAC specialists to confirm the right fit for your unit.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P550P506021CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P550P506021CP. 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 CP50P550P506021CP?
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.
