PROBLEM
: The console does not light up.
SOLUTION
: Verify the following:
Does the red light on the ON/OFF switch light up?
NOTE: Some treadmill models do not have a switch
that lights up. If this is the case, please proceed with
the yes and no solutions below.
If yes:
• Turn the power off, unplug the power cable and
wait 60 seconds. Remove motor cover. Wait until
all red LED lights have gone off on the motor
control board before proceeding. Next verify that
none of the wires connecting to the lower board
are loose or disconnected.
• Double check that all connections are secure,
especially the console cable. Unplug and
reconnect the console cable to verify.
• Make sure the console cable is not pinched or
damage in any way.
• Plug the treadmill in, turn the power switch on and
look for any lit LED’s on the motor control board.
If no:
• Verify that the outlet the machine is plugged into
is functional. Double check that the breaker has
not tripped, it is on a dedicated circuit, it is not
on a GFCI-equipped outlet, and it is not plugged
into a power strip/surge protector or extension
cord. Please see your INFORMATION CARD for specific power
requirements.
• Verify that the power cord is not pinched or damaged and is properly
plugged into the outlet AND the machine.
• Verify that the power switch is turned to the ON position.

PROBLEM
: The belt does not move, or moves briefly, but the
console works.
SOLUTION
: Verify the following:

power guidelines on pages 4 and 5 of this treadmill guide.
The unit should be on a dedicated 15-amp circuit and not

a power strip/ surge protector or extension cord.
• Check for any belt movement. If so, make note of how far
or how long it moves before stopping.
• Try to move the belt by hand. If not, the drive belt may have
come off or the motor bearings may have seized.
• Turn the treadmill off and unplug it from the outlet. Remove
the plastic motor cover located in front of the machine by
taking out the Phillip screws. Check the drive belt for proper
alignment.
• With the cover still off, check over the wire and cable
connections, as they may have become loose or
disconnected during shipping or assembly. Make sure
connections are secure and no wires are crimped,
damaged, disconnected or burnt.
