how to fix a smooth fitness 5.25 treadmill?

My smooth 5.25 treadmill stopped working after moving it from one room to another. The control panel works but the motor does not. I opened the hood over the motor,and found a blown fuse so i replaced it with a proper replacement. As soon as i plugged it in, the belt motor came on and then the fuse blew. I did this two other times, but, this time i plugged it into a power surge protector. Same thing happened. Fuse blown and the motor turns for a split second. I called the manufacturer, but, they seem to be having some financial problems and i can not get thru to any one there. My wife wants her treadmill back. Can someone please help me get this thing up and running again. Thanks.
