Question and Answers


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


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.
