Issue:
• Possible cause
Boards do not operate:
• Bad ground
• Bad battery connection
• Fuse burned
• Magnet is too far away from Sensor
• Bad receiver connection
• Sensor battery low
Board creaks or squeaks during operation:
• Gear shaft wedge bolt is loose
• Loosen mounting bracket and board attach-
ment screws. Adjust linkages so they are
parallel to each other and the noise is gone.
Tighten all fasteners.
Intermittent operation:
• Bad battery connection
• Bad ground
• Magnet is too far away from Sensor
• Bad receiver connection
• Sensor battery low
Boards operate randomly:
• Wire connections not secure
• Magnet is too far away from Sensor
• Bad receiver connection
• Sensor battery low
Board stays down all the time and can be moved
by hand:
• Gear shaft wedge screw is missing or loose
Board shakes and or shutters during operation:
• Bad ground
• Wire connections not secure
• Bad battery connection

NX Troubleshooting
Delay in board operation or boards operate
after doors are shut:
• Magnet is too far away from Sensor
• Sensor battery low
Board hits body
• Install supplied adhesive bumper per the
installation instructions.
Board does not fully retract or deploy
• The board is designed to stop travel when
the system senses a load. Misalignment can
cause the board to stop early. Remove the
motor and adjust the linkage alignment until
the board moves up and down freely without
resistance by hand.
Board retracts when doors are left open for a
long period of time.
• This is normal to save sensor battery life.
Adjusting Linkage alignment:
The board is designed to stop travel when the system
senses a load. Misalignment can cause the board
to stop early.
To adjust, remove running board and motor. Loosen
mounting brackets. Adjust linkages parallel to each
other. Shift the running board on linkages 1/8” in either
direction and carefully set board on linkages. Start
only a few threads of the allen head bolts – do not
tighten yet. Lift running board to retracted position.
Tighten allen head bolts that attach running board
to linkage. Last, tighten linkages to body. Cycle
running board by hand without motor and confi rm
zero resistance. Install motor and test.
