Use a non alcohol based silicon spray or liquid. The WD40 brand make the 3 in 1 silicone spray and it’s good for all non waxed running belts. Just make sure you get the spray in the middle of the belt. (Underneath of course) watch a YouTube video if unsure.

This usually means a faulty LCB or motor.The fact it has not been used much doesn't matter. It is 7 years old. Usually you can not see faulty parts on the LCB. I do think if you really want the answer call a treadmill repairer . If you don't know what you are doing it can be dangerous.

This could be cused by the the display cover you touch to control the functions pressing on the touch switch array just under it. Carefully remove this. it is held on by adhesive and see if the symptom goes away. If it does, look for any dents on the cover. I have worked with these type of switches for nearly 20 years and they can be problematic. The other possibility is the mechanical switches you use to increase/decrease speed or tilt. They plug in seperately and you can disconnect them to see if they are causing the problem.

If the console takesbatteries, replace them. If this does not work or your console does not requirebatteries, check the reed switch or optic sensor. Reed Switch:Unplug the treadmill and remove the motor hood cover. The reed switch is mountedon the frame next to the front roller pulley. There is a magnet glued into thefront roller pulley. When adjusting the reed switch, make sure it is pointingdirectly at the magnet. Move the tip of the reed switch within 1/8" of themagnet. Also, check to see that the wire is not damaged, and is connected tothe console. 12_3_2011_4_59_31_pm.gif2nd Step: tight the keypanel vs Display board and clean with contact cleaner spray .

Lets eliminate the motor first, unplug unit remove motor shroud fin the 2 leads from motor to lower board. Connect a 18v DC battery to the leads this start the motor to move at approx. 1 mph if it does motor is good,if not you may worn motor brushes worst case open connection in the motor.
Now if the motor is good then reconnection the leads and plug in unit the lower board should have some LEDs lit up. Now find the LED that says PWM start unit if that light should start to flicker then the upper board and wire harness are work properly. Turn off the treadmill then turn it on and with a multi meter insert the leads into the connectors that go to the motor, then put the meter on 200v DC then start the treadmill you should get a reading 5 to 10v DC if you get 0v DC then the board will need replacing
