My Proform540 treadmill works only on two speeds 1 and 4. ?
My Proform treadmill works only on two speeds 1 and 4. Other buttons on the console will not work nor will it incline. It is stuck at about mid incline. Despite pressing incline buttons, there is no reaction. I have tried reinserting key to recalibrate as stated in manual to no improvement.
