The sensor is so far away from anything metal for me to place the magnet, definitely farther than 5mm. I have the plastic wheel adjusted exactly 5 mm, all the around from the end of the roller bar. I keep getting error code 3 and it will not run longer than 7 seconds :(
Please post pics of where the magnet goes and how it should look, ya' know if anyone had their treadmill flipped over and the cover taken off.

Brenda. You know, it would be really really useful to know exactly what you are talking about.

Given the last lione in your question one assumes it is a treadmill of some kind but the make and model completely elude me.

Perhaps you could post again in this thread with all the relevant information.

Y'all know., January 2016
