A:

Your machine is not much different from most of the other machines out there. You will need to access the resistance motor and check to see if you have voltage down to it when you increase or decrease the resistance on the console.

If you do have power at the motor and it does not move that will indicate the motor has failed. You can also use a 9V smoke alarm type battery connected directly to the motor to see if it will move or not. If no movement then the motor has failed.

If there is no voltage making it down to the motor then that will normally indicate a problem with the console not sending voltage down.

Let me know what you find.

Thank you for using Manage My Life!

Q:

Our Proform 831215211 does not allow us to adjust the resistance in manual mode. Help?

A:

Several things could cause your inability to adjust tension on the bike. You could have a bad console, resistance motor, or potentiometer. Many times this is caused by a broken wire in the harness or a wire slipping out of a connector. To test the system you need a good volt/ohm meter and the knowledge to use it. There is a wiring schematic inside the bike in a plastic envelope so you can tell which wires to test. Testing the wires for continuity would be my first test.

I recommend you get a technician to diagnose and repair the bike.
