Visual Clues
The following is a breakdown of things to look for when troubleshooting these components.
Decks- Check for wood showing through black phenolic. Check for ridges or cupping of deck especially in front middle of deck. Both of these indicate that deck should be replaced or reversed if other side is unused.
Drive Motors-
1.Motor Brushes-
a.Are they worn past ½”? If so, replace brushes.
b.Are they wearing on an angle? Check that brushes are seated correctly and that motor brush holder and spring are installed properly.
2.Commutator-
a.Is it burnt, scratched, or scored? Use commutator stone to clean. If it is too badly damaged motor must be replaced.
3.Motor Shaft-
a.Does it seem to wobble? Check that flywheel and pulley are tight and in line.
b.Is shaft visibly bent? Replace motor.
Electronic Boards-
1.Any burn marks? Check for correct voltage coming in and out of board. If voltage is incorrect replace board.
2.Loose or detached components? Reattach if possible or replace if not.
Elevation Motor-
1. Check for fractured housing or broken motor mounts- Replace if necessary
Treadbelts-
1.Check for fraying on sides of belt. Likely cause is improper tracking. Check if tracked correctly. If minor, cut frayed ends off. If major, replace belt.
2.Lines or wear or top of belt one or two inches in from sides. Caused by user standing on side rails and letting heel of shoe rub on belt. Instruct user on proper use of treadmill.
3.Running on diagonal. Check the belt is tracked correctly. Check that front roller is properly aligned. Rarely, treadmill frame may be out of square.
4.Underneath belt- If belt is glazed, has black lines running through it, or is worn through backing, replace belt and use new deck surface.
Treadmill- Does it appear to be off level? Check that wheels in front are not broken. Check that feet in back are installed properly. Check that mill is on level surface and shim accordingly.
