Incline stopped working on pro-form 490cx everything else is working.incline motor works when treadmill is turned on then just stops

I assembled my Pro-Form Performance 400 a week ago and used it daily for 7 days with no issues. This morning when we turned it on and as soon my wife inserted the key it started rattle sound and inclined went on maximum and stopped on its own. I went and unlugged the power and restarted but no improvement. Then I inserted the ket and held stop key for 2 seconds then I managed to lower the incline to normal and unplugged it. After re plugging the power, now there is no light on the console. All we hear is rattling sound from incliner and went back to maximum incline. Please advise I assembled my Pro-Form Performance 400 a week ago and used it daily for 7 days with no issues.
