Malfunction Circumstance Inspection and test points Components to replace
Safety key malfunction Put safety key in place.
Display has no reaction.
“Safety key” appears on
the display.
1. Inspect the cable connections on the lower
part of the display and safety key.
2. Inspect the safety key magnet.
3. Inspect the safety key board.
Safety key board
No start up Power on indicator does
not light. 1. Inspect the power cord connection. 2. Inspect all cable connections.
3. Inspect the fuse, the fuse holder, and the
power switch.
4. Drive board components have an electrical
short. Replace the drive board.
1. Fuse, fuse holder
2. Drive board
No start up Power on indicator lights
but the display does not
light.
1. Inspect all cable connections, including
connector cables.
2. Inspect whether drive board LED2 lights:
a. If LED2 lights, inspect and test the
transformer fuse.
3. Inspect whether LED1 on the display
lights.
a. If LED1 does not light, inspect the data
cable from the display to the drive board.
b. If LED1 does light, inspect the display
program IC. Re-install the display IC.

malfunction Telemetry heart rate malfunction 1. Inspect the heart rate transmitter strap and its batteries. Replace batteries if they have
not been replaced recently.
2. Inspect the receiver board cables.
3. Test or replace the receiver board.
4. Inspect for environmental interference, for
example, from speakers and lights.

1. Inspect the soft key connection.
2. Replace the soft key. 1. Soft keys
ERR 1 Motor does not rotate, ERR
1 appears. 1. There is no power to the motor; the motor cannot operate.
2. Inspect the motor brushes.
3. Measure voltage from the drive board to the motor.
If there is no voltage, replace the drive board. If there is
voltage, inspect the following:
a. transformer voltage.
b. whether the EMG indicator lights.
c. whether IGBTs have an electrical short. Replace
the drive board.
4. Inspect motor brushes or the commutator.
1. Drive board
2. Motor brushes,

ERR 1 Motor operates, ERR 1
appears. 1. The program did not detect the optic sensor signal. 2. Inspect the CLK indicator on the drive board.
a. If the CLK indicator is not lit, clean or replace the
optic sensor.
b. If the CLK indicator lights normally, inspect the
data cable from the display to the drive board.
Re-install the display IC.
1. Optic sensor
ERR 3 Display speed differs from
actual speed. 1. Inspect KPH/MPH setting. 2. Inspect the optic wheel teeth.
3. Replace the optic sensor.
4. Replace the drive board.
1. Optic sensor
2. Drive board
ERR 7 ERR7 appears at startup. 1. Inspect the incline VR cable connection.
2. Usually ERR7 indicates the display is stuck at either
the highest or lowest position.
3. Inspect whether LED5 and LED6 light on the drive
board. If lit, the display or cable malfunction may be
causing a malfunction.
4. Inspect whether the drive board emits voltage to the
incline motor. If not, replace the drive board.
5. Recalibrate the incline set or replace the incline set as
a test.
