OEM Carrier Replacement Contactor for Carrier Model CP50P350P305521CP

Get your system cycling correctly with this authentic OEM Carrier contactor, the relay that switches line voltage to the compressor and condenser fan motor whenever cooling is demanded. As the contacts wear, you'll see symptoms such as buzzing, intermittent starting, welded contacts that keep the unit running, or a complete failure to start. This factory-spec replacement is built to the exact coil voltage, pole count, and amp rating required by Carrier model CP50P350P305521CP, ensuring proper seating and clean, repeatable contact closure. Using the correct OEM contactor protects your compressor against arcing and voltage drop that generic parts often introduce. Replacement is a quick job for a qualified HVAC technician—about 15 to 20 minutes to disconnect power, photograph and transfer the wiring lead by lead, and mount the new part. Always confirm the disconnect is open before working on the high-voltage side. We keep this contactor in stock and ship same-day on orders placed before 3PM CST. Backed by our fit guarantee for the listed Carrier model.

Frequently Asked Questions

Does this Contactor fit my Carrier Carrier Model CP50P350P305521CP?
Yes. This is the factory-specified OEM contactor for the Carrier Carrier Model CP50P350P305521CP. 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 Carrier Model CP50P350P305521CP?
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.
