My Fan won't start
Make sure all wires are securely connected and that supply power is adequate and functional. If the fan still does not start, contact Customer Service.
HOW DO I ADJUST MY FAN’S OCCUPANCY SENSOR SETTINGS USING THE STANDARD CONTROLLER?
- Press and hold the standard controller – and + buttons until the Menu screen
- Press + until you reach the Motion Sense screen, and then press the power button to enable the occupancy sensor.
- Press + to navigate to the Motion Timeout screen. Motion timeout specifies how much time should pass after no motion is detected before the occupancy sensor turns the fan off.
- Press the power button to adjust the motion timeout: 30 minutes (default), 1 hour, 2 hours, 4 hours, or 8 hours.
- Press – to exit the settings menu.
A POPPING NOISE IS COMING FROM MY FAN.
Airfoil noise occurs when airfoils are not tightened to the specified torque. Disconnect the fan from power, and then tighten the airfoil hardware to 29 ft·lb (39.3 N·m). If popping still occurs, verify that the airfoils are not contacting each other. If they are, contact Customer Service.
Note: If the hardware is stainless steel, tighten the airfoil hardware to 10 ft·lb (13.6 N·m).
MY FAN WOBBLES DURING OPERATION.
- Verify that the mounting structure is rigid enough to support the fan and that the fan is not being exposed to external air forces.
- If guy wires were installed, confirm proper installation. If guy wires were not installed, contact Customer Service.
MY FAN’S VFD GENERATES RADIO FREQUENCY (RF) NOISE.
VFDs generate RF noise in many ways, but this can be prevented using proper wiring practices.
- Do not run your fan and sensitive equipment on the same power
- Ensure proper grounding at the motor, at the VFD, and from the VFD to the utility.
If noise is still present, contact Customer Service.
MY FAN’S MOTOR MAKES NOISE WHEN THE SPEED IS INCREASED.
Audible high-frequency carrier noise may be an indicator of a stall condition.
Some motor, gearbox, or VFD noise is to be expected and is normal.
MY KEYPAD IS SHOWING “EF,” “OU,” OR SOME OTHER CODE.
This is most likely a fault code. Big Ass Fans have built-in checks that look for both internal and external faults.
If your keypad reads “EF,” your fire alarm has gone off. This fault only occurs if the fan is connected to your fire panel.
If your keypad reads “OU,” there has been a fluctuation in the power being supplied to the fan. This occurs most often after a storm.
If the keypad reads “CE-04,” or is blinking, hit the “Mode” button until the fault code appears on the screen. Then, press “Stop/Reset” to clear the fault. To restart your fan, press “run.”
Regardless of the fault code, you can clear it by hitting the “Stop/Reset” button. To restart your fan, press “run.”
“STOP” IS FLASHING ON THE KEYPAD, AND THE FAN WON’T RUN.
After a power outage or a tripped circuit breaker, the fan will default to remote operation (REM). For normal operation, the fan should be in local operation mode (LOC). To switch back to LOC mode, press the “Local/REM” button once. If the fan does not automatically start up, press “Run.”
If the fan does not switch from REM to LOC, your keypad might be locked.
NONE OF THE BUTTONS ON MY KEYPAD WORK - Locking and Unlocking the keypad

MY STANDARD WALL CONTROLLER DOESN'T WORK.
If the standard wired controller isn’t lighting up, check that the CAT5 is plugged into the controller.
