The treadmill is an exercise machine used for indoor running. Like all machines, parts can wear. Eventually if you don't fix or replace a part, the machine itself could become severely damaged. The fuse is an important part of the treadmill machine, as it is used for the elevation motor, which controls the incline. If the fuse on your treadmill has blown, it's time to replace it.
Read the user manual of your treadmill to find the elevation motor. The treadmill fuses are located inside the elevation motor. If you don’t have the manual, contact the manufacturer of the treadmill and ask if it can send you one or if there is one you can download online.
Turn off the treadmill and unplug it. If you have recently used it, let it cool down for one hour before opening.
Place the treadmill on its side and use a screwdriver to unscrew the lid off the elevation motor. Carefully remove the fuses. Some treadmills have easy access to internal parts where you don’t need a screwdriver. If this is the case, simply lift the lid off.
Take the faulty fuses to a hardware store to make sure you purchase the correct replacement fuses.
Insert the new fuses into the elevation motor and close the lid. Plug in the treadmill to see if it works.
