Preventative Maintenance On A Proform Performance 300 Treadmill (No Unnecessary Dialogue) 

I contacted proform regarding this topic. The Ai said to use the Treadmill Maintenance Kit TMAK213. Don't know why the manual says that but it's b.s

Run

Check the hinge points on the bar the incline motor is attached to.... where it bolts into the frame for tightness. The shifting belt suggests possible frame damage at a weld, or issues with one of the rollers.

@@gitfit875 thank you I appreciate it

Yes, trying to kick it out of alignment

As far as maintenance, it should be almost exactly the same

Sounds like the controller (speed burst)

@@gitfit875 do you have information on how to fix this? Or do I have to buy a new controller?

@@arnervillahermosa6366 I wish I was that savvy! There are guys online who can repair them. If it's an icon machine, controllers aren't too crazy expensive. Not sure what you meant about stuck on repeat though..... if a motor had dead spots that would also run erratically..... sort of like constant speed bursts. You can test the motor with a drill battery to rule that out.

@@gitfit875 seems like the controller has a defect. It is speed burst. It constantly rev up the motor then returns to the proper speed then speeds up again

@@arnervillahermosa6366 yep.... controller

I would think so, might be worth a phone call to them to verify...800 677 3838
