Used Treadmills

 You obviously want low-friction contact between the deck and the belt. Damage to the motor electronics is more likely if the friction between the deck and belt is high. Neither will they be easy to dead-walk on when the power is off. Basically, high friction belts can cause the motor to stall – a situation which you would never want to happen as this is one sure-fire way of damaging your treadmill’s motor. Lubrication when unnecessary can lead to excessive amp draw and subsequent damage to motor electronics.

Blown Fuses: You don’t usually discover blow fuses, unless you are doing or having someone do some technical diagnostics on your treadmill. And even then, it is generally not recommended for users to replace blown fuses in the motor or motor controller themselves.

When replacing blown fuses, you have to use the recommended fuse. This is true even if you’re referring to an electronic piece that isn’t a treadmill. When it comes to treadmill fuses, however, you have to understand that they are not interchangeable with automotive fuses. And so, if you discover a blow fuse in your treadmill, do not even attempt to make replacements on your own. Instead, contact a dealer for proper replacement.
