Every piece of electronics has a component that acts as the basis to the central nervous system. If that central component malfunctions, you have a serious problem. This is the case for the treadmill motor control board. However, fixing a faulty motor control board isn't too complicated. Make sure you have the treadmill manual, the proper tools and a replacement control board to swap out the faulty one.
Turn off the treadmill and unplug it from the electrical socket or surge protector.
Remove the motor cover with your screwdriver by removing any screws. Refer to your treadmill manual because the location of the motor cover and the number of screws varies per model.
Detach any wires that are connected to the control board but leave them connected to the treadmill. Make sure the LED on the control board is off before removing wires carefully with your hands. Your treadmill may contain wires such as elevation wires, on/off connections, motor wires and sensor wires, but refer to your treadmill manual for all the wires to detach because models vary for the number and type of wires connected to the control board.
Remove the control board.
Clean the inside of any dust with the can of compressed air because dust can cause issues with the treadmill.
Install the new control board.
Reconnect all the wires and screws to the new control board.
Install the motor cover back in its place with all the needed screws.
Recalibrate the treadmill per the manual. Treadmill calibration is when you accurately register the incline and speed feedback of your treadmill. This should be done every time you replace your control board or motor.
Perform regular cleaning of the treadmill to keep its performance consistent and to prevent future issues.
Performing work on the treadmill while the power is on or the unit is plugged in can cause possible electrical shock to you or damage to the unit. Not calibrating the unit once the new control board is installed can cause damage to the unit and/or a decrease in performance.
