Nibe 718248 – DC Fan Motor

Replacement Motor for Outdoor Air Source Units

The Nibe 718248 Fan Motor (DC) is a high-efficiency, electronically commutated motor (ECM) used in Nibe’s larger F2040 air source heat pump units. This motor powers the outdoor fan responsible for airflow across the evaporator coil — critical for efficient heat exchange and reliable system operation.

🔧 Technical Overview:

• Nibe Part Number: 718248

• Motor Type: DC / ECM (Electronically Commutated Motor)

• Application: Outdoor fan drive

• Mounting: Factory-fit to fan bracket in outdoor module

• Power Supply: 230V (connected via system control board)

✅ Compatible Nibe Models:

• Nibe F2040 – 12 kW

• Nibe F2040 – 16 kW

This motor is specifically used in the larger capacity variants of the F2040 series due to the higher airflow requirements.

🛠️ Engineer’s Recommendation:

💡 When replacing the fan motor, it's strongly recommended to order the corresponding fan blade at the same time.
Fan blades can develop stress fractures, imbalances, or mounting wear that may not be visually obvious but can affect the new motor's performance and lifespan. Also very diffcult to remove from motor drive.

🔧 Common Replacement Reasons:

• Fan not spinning or starts/stops intermittently - Fan alarm error 

• Low  pressure faults due to poor airflow

• Audible motor noise or vibration

• ECM error codes from the control board
