I am trying to repair an incline inoperative troubleshooting of a lifefitness treadmill 9700HR, but so far no luck. There is a message in the display that says ¨please wait¨ and then incline inoperative, after this the message of "if desire continue" appears, then it seems like if it's going to begin but the motor doesn't move, but the treadmill functions like if it is working normally, showing the time and the speed. Could you please help me on this???? Thanks, Leonardo Bastida
