What HP motor do I need for my Carrier unit?

The correct replacement for Carrier model Model FK4DNF002000AAAA is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number Model FK4DNF002000AAAA.

My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Is this fan motor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Fan Motor HD46AE120 for Model FK4DNF002000AAAA

This OEM Carrier blower fan motor (HD46AE120) drives the indoor blower wheel that circulates conditioned air throughout your home on the Carrier FK4DNF002000AAAA fan coil unit. The motor is the heart of your airflow — when it fails you'll experience no air from the registers, weak airflow, loud bearing noise, or a motor that overheats and cycles off on thermal overload. This genuine OEM motor is matched to the FK4DNF002000AAAA's horsepower, RPM, rotation, and shaft dimensions, ensuring correct airflow (CFM) and quiet operation that generic motors can't reliably deliver. Installation is moderate to advanced: a technician transfers the blower wheel, sets the same shaft position and rotation, and rewires the capacitor and speed taps — typically 45-60 minutes. Professional installation is strongly recommended for proper alignment and electrical connections. We keep this motor in stock and ship same-day on orders before 3PM CST to minimize comfort downtime. Restore full, balanced airflow with a genuine Carrier OEM blower motor engineered for long, dependable service.
