3.3 TROUBLE SHOOTING
3.3.1 TROUBLESHOOTING NO POWER TO THE CONSOLE
1) Symptom:
No power to the console.
2) Solution:
a. The adaptor for this model is 12V - 2A. Check to make sure the power adaptor on the unit is correct.
Test the power adaptor on a known good outlet. Replace the adaptor if it is defective.
b. Check the connection of the console cable at the console. Unplug the console cable from console, and
use a multi-meter to check the voltage through the console cable. Pin 1 or 2 and pin 7 or 8. it should be
12VDC. If no voltage is present, the console cable is defective, replace it.
c. If the voltage through the console cable is 12VDC, the console is defective, replace it.
3.3.2 TROUBLESHOOTING SPEED DOES NOT DISPLAY
1) Symptom:
The speed value does not display on console
2) Solution:
1. Unplug power cord, remove the console and check that all connections to the console are secure and
not damaged or pinched.
2. Remove the side cover and check to see if the sensor wire is connected well.
3. Check to see if one corner of the sensor is aligned with the magnet and the distance less than 5mm.

CHAPTER 3: Troubleshooting
3.3.3 TROUBLESHOOTING NO RESISTANCE OR INCORRECT RESISTANCE
1) Symptom
a. The resistance is not adjustable during an exercise.
b. The resistance is reversed or much too high.
2)Solution
a.Please refer to XR/XER/XIR service manual to check console for correct model selection first
b. Remove the front shrouds. Turn on the console, and check the ECB motor. At resistance level 1, the
head of the steel rope should point towards the top right side (around 45 degrees Fig A). If the head of
the steel rope points toward the bottom or left side, the resistance will be reversed, adjust the head of the
steel rope to the correct position.
c. Press the LEVEL UP key to adjust the resistance.
A) If ECB motor cannot move, the resistance will not be changed. The ECB motor or console cable is
defective. Check the console cable inserted in ECB motor. Re-connect the console cable first, if still not
working, test cable for damage. If test good, replace ECB motor.

CHAPTER 3: Troubleshooting
3.3.3 TROUBLESHOOTING NO RESISTANCE OR INCORRECT RESISTANCE
B) If the ECB motor can move, the resistance can be adjusted. If the resistance is still too high, check the
gap between orange block and the bottom. It should be within 1-2 mm.
If the gap is larger than 1-2 mm, the resistance will be heavier than normal. Adjust the cable to the correct
gap range.
3. If all above conditions are ok, and the resistance is still too high, inside magnet is defective Replace the
ECB.

CHAPTER 3: Troubleshooting
3.3.4 TROUBLESHOOTINGHEART RATE ISSUES
Symptom: Heart Rate Function Does Not Work or is Reading Incorrectly
Solution:
1. The heart rate grips are not connected properly or are defective.
With a multi-meter set for DC voltage, place one terminal on each of the HR grip plates. The HR grip
should give a voltage reading of between 0.5 and 2.0VDC. If the voltage is not between 0.5 and 2.0VDC,
remove the 3 screws holding the HR grip together and check the connection of the HR grip wiring.
2. The heart rate grip wiring is damaged or not connected correctly.
Check continuity of the HR grip wiring.
Place one terminal of a multi-meter set for resistance on the HR grip wiring at the HR grip, and the other
terminal on the HR grip wiring at the console. An ohm reading of around 1 should be expected. If the
reading is higher than 1, replace the HR grip wiring.
3. The HR board is damaged
Remove the console. Remove the 6 screws holding the front of the console to the rear. Check the
connection of the HR board wiring to the UCB. If all the wiring is intact and has good contact, replace the
HR board.
4. The UCB is damaged.
If the HR board, HR grips, and HR grip wiring do not solve the issue, replace the UCB.

4.4 CRANK REPLACEMENT
1) The crank arm is fixed with a self-extracting crank bolt. You must lubricate under extractor cap before
removing the crank bolt. If this is not done, damage can happen to the crank arm or extractor.
2) With an 8mm hex key, turn the crank bolt counter-clockwise to remove crank arm. The torque is
800lbs (Figure A).
3) Reverse to replace the crank arm.
