Berko 3900-2008-001 Motor

The Berko 3900-2008-001 Motor is a precision-engineered replacement component designed for compatibility with specific Berko and QMark 3900 series electric unit heaters. Operating at a dual voltage range of 240/277V, this permanent split capacitor motor delivers a consistent 1550 RPM output, ensuring optimal CFM performance in heavy-duty commercial or industrial heating applications. Built with a Clockwise (CW) rotation (determined from the lead end), it matches factory specifications for load requirements and shaft dimensions, preventing common issues like excessive vibration or premature bearing failure. For technicians servicing fan-forced unit heaters, this 1/40 HP motor ensures the heating elements receive proper airflow to prevent thermal limit tripping. Integrating this OEM replacement motor restores system efficiency and maintains the manufacturer’s specified air throw patterns. Always verify lead wire length and mounting bolt patterns against the existing chassis to ensure a seamless drop-in installation.

• Dual Voltage Versatility: Direct compatibility with 240V and 277V circuits commonly found in commercial heating distribution.
• Verified RPM Output: Maintains 1550 RPM for consistent heat dissipation and airflow across the heating coils.
• OEM Fitment: Designed specifically for Berko 3900-series cabinets, eliminating the need for mounting bracket modifications.
• Thermally Protected: Built-in protection against overheating to safeguard the motor during high-demand cycles.
• Durable Construction: Engineered for the high-duty cycles required in warehouse and mechanical room environments.

What is the rotation direction for the 3900-2008-001 motor?
This motor is rated for Clockwise (CW) rotation as viewed from the lead end/back of the motor.

Can I use this motor in a 120V system?
No, this is a dual-voltage 240/277V motor. Operating it at 120V will lead to torque failure and potential coil damage.

Is the capacitor included with this replacement?
This motor typically utilizes an internal or pre-wired configuration, but you should verify your existing heater's wiring diagram to ensure proper lead connection.
