My ProForm Treadmill Motor Cuts Out When Running

Updated April 17, 2017

Walking or running on a treadmill is a low-impact method of cardiovascular exercise. Routine maintenance is needed to keep your treadmill functioning properly. If the motor of your Proform treadmill cuts out or begins to slow while you are working out, it may be a sign that the belt needs to be adjusted. A belt that is not properly adjusted places undue stress on the motor of the treadmill causing it to slow and cut out during use.

Remove the safety key. This will bring the belt to a gentle stop. Step off the treadmill carefully.

Remove the treadmill's electrical plug from the outlet.

Turn both rear roller adjustment bolts counter clockwise one-quarter of a turn using an Allen wrench. The bolts are located on the back end of each side rail.

Lift the walking belt in the centre. When the belt is properly tightened, the belt should lift two to four inches off the walking platform.

Plug the power cord into an electrical socket. Insert the security key into the slot.

Allow the belt to run for at least two minutes to properly adjust.

Walk on the treadmill to test the tightness.

Contact Proform customer service if the motor continues to cut out after troubleshooting.
