OEM Carrier Contactor Replacement Part for Model CP50P450P405011CP

This genuine OEM Carrier contactor is the heavy-duty relay that switches line power to the compressor and outdoor fan whenever your thermostat calls for cooling. Built for Carrier model CP50P450P405011CP, it supplies the exact coil voltage, pole count, and contact rating the unit was engineered for, eliminating the chatter, pitting, and short-cycling that generic parts introduce. A failed contactor is a leading cause of a system that hums but won't start, or one that won't shut off because the contacts have welded together. The good news is that swapping it is an easy repair — most handy homeowners and all technicians can finish in about 20 minutes. Cut power at the disconnect, snap a photo of the existing wiring, move each lead to the matching terminal on the new contactor, and remount it. You'll get back crisp, reliable startups and protect the compressor from damaging voltage drop. We keep this part in stock, and every order placed before 3PM CST ships the same business day so your repair isn't waiting on shipping.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CP50P450P405011CP?
Yes. This is the factory-specified OEM contactor for the Carrier Model CP50P450P405011CP. 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 CP50P450P405011CP?
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.
