There is a support option at the website to help you determine if the motor needs to be replaced.

If one of the buttons is stuck, none of the buttons will work.
Try using a hair dryer to free the stuck button. the heat (use low) will cause the button to expand and might free the button.
Otherwise, the consoles are not repairable, and are a straight replacement item. Call Icon Fitness for parts pricing.

Hi Dan,

I know it's been a while, but any chance you found the issue and fix? I have the exact same model and same symptoms you mentioned.

thanks

If you wish to get some details; check the site linked here. Pull up older posts.......

if this is a stationary bike, look on the wheel for a hand operated knob that has a roller on the tire itself.. this is a tensioner..it will need tightened up..the tighter you go the more resistance you get.the new ones use electronic braking system..dont now how it adjusts except by the control module..

Speed, distance, time, calorie doesn't read on display. The heart rate monitor works great, what is the problem? Speed sensor?

I have freemotion treadmill t12 ,and it says on the screen 0x00 and 0x23 ,anyone knows what are those errors?thanks in advance

Whats wrong with it?

Hi Doug,
You may have a problem with the resistance motor. The covers will have to be taken off to fix.
Usually when you increase or decrease the resistance you will hear the motor working. Do you hear it ?
