CONSOLE/DISPLAY PROBLEMS
Symptom
Blank Console
Solution
1.
2.
Symptom
Console starts ok,
but goes blank after a
few seconds of use.
Symptom
Display goes into
engineering mode by itself
Date of last revision: 11.07
Check power as follows:
• 5.5VDC and 14VDC need to be present at the console while pedaling
slowly. Check voltages at console AND lower board (see electrical
diagram and System Detail Supplement).
• If correct voltages are present at console, replace console.
• If voltages are not present at console, check lower board.
- If voltages are present at lower board BUT NOT at console, replace
wire harness.
- If voltages are not present AT LOWER BOARD, check generator
voltage.
Check generator (see electrical diagram and Troubleshooting Supplement).
• If generator voltages are correct AND equal between phases, replace
lower board.
• If generator voltages are incorrect, replace generator.
Solution
1.
Console is not receiving RPM signal from lower board.
• Check RPM signal at lower board. (see electrical diagram) If signal is
present at lower board check for signal at console.
• If signal is present at console, replace console.
• If signal is present at lower board but NOT present at console, replace
wire harness.
Solution
1.
JP1 pins behind console are touching (shorted).
• Separate the 2 pins from touching

SPEED AND CALORIES PROBLEMS
Symptom
Speed/Distance values
seem way off.
Symptom
ALL Speed, Distance,
Calories, and Watts
readings are missing.
Symptom
Calories are double or
1/2 of correct value.
ELLIPTICAL.TROUBLESHOOTING.EP77.REV1
Solution
1.
Miles/Kilometer switch in Engineering Mode is set incorrectly
• Change in Engineering Mode
Solution
1.
2.
Check for presence of RPM signal in Engineering Mode
(See Engineering Guide- SUBGROUP Eng3)
If no RPM display in Engineering Mode, signal is likely missing at console
• Check wire harness, lower board and generator(See electrical diagram
and Troubleshooting Supplement)
Solution
1.
Console may be configured for Bike.
• See engineering guide to configure console for Elliptical

HEART RATE PROBLEMS
Symptom
No Heart Rate
Symptom
No Heart Rate
(After checking for
environmental disturbances)

5.
Symptom
Heart Rate is
intermittent and/or
erroneous
Clean grip contacts with rubbing alcohol.
Check HR function in Engineering Mode (See Engineering Guide - SUBGROUP
Eng3)
If no heart rate from chest strap OR contact grips:
• Replace console
If no heart rate from chest strap, but HR works with contact grips:
• Replace transmitter or transmitter batteries
If no heart rate from contact grips, but HR works with chest strap:
• Check all connections between grips, grip wires and console
• If all connections seem ok replace grips and wires
• Replace console

ALL HEART RATE ISSUES should first be addressed by eliminating any possible
environmental disturbances. Such disturbances can be caused by:
• Electronic pet fences, cell phones, cordless phones, TV remotes, TVs in
close proximity, radios and stereos in close proximity, satellite dishes,
fluorescent lights, etc.
Clean grip contacts with rubbing alcohol.
Eliminate any environmental disturbances. (see HEART RATE ISSUES above)
Check HR function in Engineering Mode (See Engineering Guide - SUBGROUP
Eng3)
Check transmitter batteries
Check all connections between contact grips, grip wires and console
• Replace transmitter/batteries and/or grips and wires.
• Replace console

Resistance is too weak
or too strong

Check connections of the braking resistor at the lower board. The Braking
Resistor is the very large external (aluminum) resistor mounted on the frame of the
elliptical or trainer in close proximity to the lower control board. If the Braking
Resistor is not connected securely ALL resistance will be lost
• See electrical diagram
Check Brake Function Test in Engineering Mode
(See Engineering Guide - SUBGROUP Eng4)
Check connections of the wire harness at the lower board and the console. The
console controls the resistance level via the D/A signal.
Check the D/A voltage level at the lower board. (see electrical diagram AND
brake voltage chart)

NOISE PROBLEMS
Symptom
There is a squeak or noise
that appears to be coming
from the roller wheels.
Symptom
Solution
1.
Solution
1.
If the noise is in one
particular spot during the
during the rotation of the disk
2.
(i.e. the three O’clock
position), the noise can be
narrowed to external linkage,
or crank bearings.
Symptom
Check the tightness of all external linkages. If you find a loose or sloppy joint,
tighten the hardware to this joint. It may be necessary to add a wavy washer to
some joints.
If all external linkages are tight, it is likely that the crank bearings are bad.
Replace the crank bearings or crank assembly.
Solution
1.
If the noise can not be
narrowed down to a specific
position during the rotation of
the disk, it is likely that the
problem is related to the
flywheel or center axle set.
Date of last revision: 11.07
Verify that the roller wheels and tracks are in good condition. Assure there are
no bumps or dents in either. Clean both the wheels and the tracks.
Remove the covers and check the flywheel operation. Change flywheel bearings
if necessary.
