Q-Mark 3900-2014-004 Fan Motor
This Q-Mark 3900-2014-004 fan motor serves as an OEM replacement component for compatible HVAC equipment. It is designed for new installations or repairs requiring a direct substitute motor. The unit operates across 208, 240, or 277 volt supplies. It suits technicians and facility managers maintaining specific air-handling systems.
Voltage Compatibility Check
Before ordering, confirm that the existing system supplies 208, 240, or 277 volts to the motor terminals. Verify the original motor’s nameplate voltage matches one of these three ratings exactly. Ensure the wiring configuration and mounting arrangement align with the replacement unit. Cross-reference the equipment service manual for the correct part number.
OEM Motor Replacement Use
This motor replaces a failed or worn OEM unit carrying the same 3900-2014-004 designation. The upgrade is worth it when the original motor no longer starts, runs hot, or draws excessive current. It restores rated airflow without modifying the drive assembly. Buyers needing a different voltage range, frame size, or shaft configuration cannot use this model.

Questions about this item
Does the Q-Mark 3900-2014-004 fan motor ship with mounting hardware or a capacitor, or must those be purchased separately?
The listing describes only the OEM replacement motor itself; mounting brackets, capacitors or wiring accessories are not included and would need to be sourced separately.
Which voltage setting should I select for a 240 V supply when installing the 208/240/277 V motor?
The motor is rated for 208, 240 and 277 volts; for a 240 V circuit you simply wire it to the 240 V tap — no internal switching or jumper change is required.
What does the 208/240/277 V rating mean for day-to-day operation in an HVAC unit?
It means the motor will run correctly on any of those three common North American supply voltages, so the same replacement part covers 208 V, 240 V and 277 V installations without modification.
