ProForm 831.24624 I used this machine a few days ago. Everything seemed to be working fine. I moved it to a different room. Now the display panel comes on. Everything lights up like always. I put the key in its place. I hear the beep as if its ready for my workout. Then nothing. I press buttons and the belt doesnt turn, doesnt incline and the fan doesnt come on. What have I done wrong? This machine has been used very little. I am the only owner so I do know of its use.
