TROUBLESHOOTING

GENERAL TROUBLESHOOTING GUIDELINES

This section outlines several tests to systematically identify and isolate the cause of problems in the electrical system and the drive train. This troubleshoot- ing section is organized into four basic problem sections: Electrical System, Console Diagnostics, Speed Control, and the Drive Train. The first step is to identify the problem. Once you have identified the problem, perform all the tests in exactly the same order as written. Refer to the “Parts Removal and Replace- ment” section of this Manual for all disassembly and assembly instructions. To order a replacement part, or to get help with the troubleshooting process, contact our Customer Service Department at 800-331-3578. International customers should contact their local distributor or call 425-823-1825.

TROUBLESHOOTING THE ELECTRICAL SYSTEM

The electrical system consists of: the power supply, main cable, relay board, load resistor, and the console. In order to identify the component that is causing the problem, you must systematically test the system. You will need a volt-ohm meter (multimeter) to conduct portions of the following procedures. The console and power supply are not serviceable by the owner. If either of these parts are inoperable, they must be replaced. Opening the console or the power supply will void the warranty.

The Console Fails to Power Up

A.Perform a visual check of the machine. Check the following things first:

1.Is the power supply plugged in?

2.Is the indicator light lit on the power supply? If it is, proceed to step #3. If the light is not on, go to step B.

3.Replace or exchange your console with a console you know is good and retest the machine.

B.Verify AC power.

1.Disconnect the AC power cord from the AC wall outlet.
