When I push start, the treadmill starts and then you can hear a "click" and the belt stops, but the timer keeps running.

Remove bottom motor hood. Is the red KLED lit on the controller? When you press start does it beep and does the timer start? No LED replace controller. No beep or timer start console keypad is bad.

seethe video and proceed according. God bless you

please LUBE the deck belt inmediately.

2) LUbe the rollers bearing too

3) test the input voltage motor , if there are the motor need repair.

4) Test the output motor board,if there are NOT voltage the board is faulty.

Sounds like you need a motor. If it is sparking a lot when it moves, the commutator and brushes may need to be rebuilt or the motor replaced..

Most likely a bad drive belt. Take the cover off the motor area. If you see black dust near the left side of the motor, replace the drive belt.

My Proform 550 doess not work the treadmill is not getting any power. Wht might the problem be.

check the voltage at the outlet for 220
