5. **Installation Challenges** If the motor is not installed correctly (e.g., improper wiring, sealing, or alignment), it could lead to inefficiencies, noise, or even damage to the system.
6. **Limited Customization** Unlike some high-end systems, this is a standard replacement part with fixed specifications. If your system has unique requirements, you may need additional components.
