Trotter Treadmill Repair
Some treadmills are easily repaired.

Trotter treadmills can develop certain problems that require repairs. The machines have complex wiring circuits and sophisticated motors and things can go wrong. Major repairs to the console wiring and treadmill motor should be left to a certified technician. This is especially important with any piece of exercise equipment where terms of warranty are specific. Minor repairs to the running belt and deck are not complicated for anyone with some degree of mechanical aptitude. Making minor repairs and adjustments to Trotter treadmills begins with compiling a few basic hand tools.

Step 1

Unplug the power cord from the electrical outlet. Raise the console to the full upright position if the treadmill is folded. Use a hex wrench to loosen the running belt tension by turning the adjustment bolts at the rear of the treadmill counterclockwise. Remove the left side end cap at the base of the unit with a Phillips screwdriver and remove the side panel along the left side of the running deck. This exposes the front and rear rollers and running belt.

Step 2

Remove the running belt from the front and rear rollers for inspection. Cracks or dark spots on the inside surface of the belt indicate the belt needs to be replaced. Wear on one or both edges of the belt usually indicate the belt has been out of alignment. Use an Allen wrench to remove the bolts that hold the running deck to the treadmill and remove the deck.

Step 3

Locate the Phillips head screws or Allen bolts that secure the motor cover and remove these with a Phillips screwdriver or Allen wrench. Lift the motor cover up and off the treadmill. Trace the black and white wire leads on the treadmill motor to the connection posts on the circuit board near the front of the treadmill frame.

Step 4

Pull the connectors off the posts and use a voltage meter to check the continuity of the motor wiring circuit. If the meter does not show a reading, have a qualified technician diagnose the electrical circuits. If the meter shows a reading you can replace the black and white connectors onto the terminal posts and reattach the motor cover.

Step 5

Clean the circuit boards, motor and under-deck areas with compressed air. Turn the running deck over and reinstall it on the treadmill. The Trotter Elite has a nonreversible deck that may need to be replaced if worn excessively. Clean the surface of the running deck with a moist cloth to remove any dust or debris.

Step 6

Install the existing or new running belt onto the front and rear rollers. Reattach the treadmill side plate and end cap. Tighten the belt adjustment bolts to medium tension. Refer to the owner’s manual for procedures to adjust the running belt tension and alignment. Do not use the treadmill until the belt tension and alignment are correct.
