Treadmill Belt Slipping
Be careful when testing for a slipping belt. A danger of a fall and serious injury is always present.
How To Adjust A Treadmill Drive Belt
The motor drive belt is adjusted independently from the walking belt. Some newer models have an auto tensioner which is a lever that has a wheel that puts pressure on the drive belt and a spring on the other end that automatically loads the belt to the proper tension. You should not adjust these since they are preset.
Symptom- No Motor Output
The single most cause of no motor output is failure of the DC motor control. Before you attempt to determine if it is the control, you must first rule out simple things.
Belt Loses Power (Bogs Down or is Sluggish)
This condition is when the treadmill operates normally without a person on the belt and then slows down when someone steps on the belt or when the treadmill operates normally for a given period of time with someone on the belt then abruptly begins to slow down.
Shuts Down During A Workout
If you can walk on your treadmill but it shuts down during a workout, it is normally caused by a friction problem with the belt and deck.
