Models Affected:
A30 Ascent Trainers
(EP701, EP711)
Use the table below to troubleshoot resistance issues. If a symptom has more than one possible cause,
complete the test and, as necessary, the repair, to eliminate each possible cause, in order, until the issue
is resolved.
IMPORTANT:If the repair column states to replace the ECB motor1, follow the instructions on page 5.
Symptom
Possible Cause
Test Procedure
Repair
Resistance is
backwards
Tension wire is not
connected to the
brake or has failed
Verify that the tension wire is
connected to the brake and has not
failed.
Reattach the wire.
Tension wire is not
looped correctly
around the motor
wheel
Check the wheel/tension wire
orientation (see photo of ECB Motor
Tension Wire Orientation on page 3).
Uninstall and then
reinstall the original
ECB motor.
Damaged ECB
motor
Verify whether the issue reoccurs
after the original motor is reinstalled.
If the issue reoccurs,
replace the ECB
motor.
Magnetic brake
positioned
improperly
Check the position of the magnetic
brake (see notes for Magnetic Brake
Position on page 4).
Reposition the
magnetic brake.
Resistance is
erratic;
accompanied by
a ticking and/or
clicking noise
from the ECB
motor
Damaged ECB
motor
Look/listen for signs of damage (see
photo and descriptions of ECB Motor
Damage on page 3). If noise is
present, confirm itiscoming from the
motor.
Replace the ECB
motor.
No resistance
Tension wire is not
connected to the
brake or has failed
Verify that the tension wire is
connected to the brake and has not
failed.
Reattach the wire.
Failed or improper
power supply
Perform a voltage check on adapter.
Verify that the adapter is the correct
voltage.
Replace the power
supply.
Unit is in Demo
Mode
Check to see if Demo Mode is turned
on.
Turn Demo Mode off.
1The parts list and/or service manual may describe this part as the “resistance motor” or “servomotor”.

2| Revision Date: 2/4/2020 | Revised by: EM
No resistance
(continued)
Connection and/or
communication
issue; failed
console cable
- Check the console cable
connections.
- Verify the console cable is not
pinched or damaged. Perform a
voltage check on the console
cable.
- Reseat any loose
connectors.
- Replace the
console cable.
Damaged/failed
ECB motor
Press the up or down arrow to adjust
resistance. Meanwhile, observe the
black wheel on the ECB motor: does
it turn at all (with or without the
tension wire attached)?
- If the wheel turns without the
wire, but not with the wire, the
ECB motor is damaged.
- If the wheel doesn’t turn at all,
confirm Demo Mode is off. If the
issue remains, the ECB motor
may be burned out.
- Perform a voltage check on the
ECB motor.
Replace the ECB
motor.
ECB motor skipping
- Check the tension wire. If it is
routed incorrectly, try to fix the
routing issue.
- Press the up or down arrow to
adjust resistance. Meanwhile,
observe the black wheel on the
ECB motor: does the wheel
start to rotate and then bounce
back to its original position
(“skip”)?
If the tension wire
routing issue
reoccurs after it is
fixed, or if you
observe the wheel
skipping, replace the
ECB motor.
MCB issue
Troubleshoot the MCB; reference the
unit’s service manual for more
information.
Reference the unit’s
service manual for
more information.
Failed quick key
connection
- Verify if the wrong quick key
connection cable was used
(A30/E30).
- Perform a resistance check.
Replace the quick
key connection
cable.
Failed console
--
Troubleshoot the
console.

APPENDIX
ECB Motor Damage
If appropriate installation steps are not followed while installing the ECB motor, the tension wire bracket
and/or internal motor gears can become damaged.
- If the internal gears are damaged, a ticking or clicking noise may come from the motor.
- The photo below shows a damaged tension wire bracket. It’s not possible to repair the bracket, so
if this part is damaged, the motor must be replaced.
ECB Motor Tension Wire Orientation
When installed correctly, the tension wire loops down and then around the black wheel. The photo below
shows the motor in correct position when the unit is at the lowest resistance level.

4| Revision Date: 2/4/2020 | Revised by: EM
Magnetic Brake Position
The photo below shows the gap between the orange block and the bottom of the ECB (flywheel) track.
When the unit is at the highest resistance level, the gap should be 1-2 mm.
If the gap is larger than 1-2 mm, the resistance will be higher than normal. Adjust the cable to the correct
gap range.

ECB Motor Replacement Procedure
Required Tools:
•Phillips screwdriver
•Needle nose or bent nose pliers
Follow these steps to replace the ECB motor:
1. Turn off and unplug the unit.
2. Using a screwdriver, remove the appropriate covers to access the ECB motor.
3. Remove the old ECB motor: unplug two wires from the resistance motor, disconnect the tension
wire, and remove 4 screws to remove the motor from the frame.
4. Plug in the new motor. (The black sensor wire plugs into the side, and the white/blue
communication wire plugs into the top of the motor.)
5. Use a screwdriver to remove the black wheel from the motor; set the wheel and screw aside.
IMPORTANT: Do NOT move on to the next step until the black wheel has been removed.
6. Plug in and power on the unit. Once the console powers on, the motor will automatically adjust to
position itself at the lowest resistance level. You may see the white pulley socket rotate.

7. Use a screwdriver to attach the motor to the frame (reuse the screws that were removed in step
3). (The motor may continue to adjust as you complete this step.)
IMPORTANT: After completing step 7, wait for one full minute before beginning step 8. This ensures
the motor will complete any final adjustments before you reinstall the tension wire.
8. Thread the tension wire through the bracket.
9. Attach the puck on the tension wire to the black wheel.
10. Pull to extend the tension wire to its full length. Once you’ve extended the wire, use pliers to hold
it taut near the bracket.

11. Reattach the wheel to the motor:
•Rotate the black wheel clockwise until there is no slack in the tension wire. It is important
to orient the wire correctly, looping down and then up around the wheel. The wire’s path
is illustrated by the red arrow in the photo below.
•Press the wheel into the ECB at the closest point that the hex will fit in, making sure the
tension wire is as tight as possible.
12. Use a screwdriver to reattach the wheel to the motor.

8| Revision Date: 2/4/2020 | Revised by: EM
13. Test the unit.
•When the cable is fully extended against spring tension, the resistance should be at
minimum (see photo below).
•When the cable is not extended, the resistance should be at maximum.
Note: The pulley completes just over half a (counter-clockwise) rotation from minimum to
maximum resistance.
14. Reattach all covers.
