Loss signal: 3 possible areas that can be causing the problem speed sensor , motor control Board ( MCB ) or the drive motor. Unplug unit remove motor shroud then plug in unit now on the MCB their should be L E D s lights should be on. One of the L E D s should speed on other P W M . Start your treadmill you see the PWM light flickering thus the upper console and cable connections are good now it will go back L S. Reset your treadmill then manually start pushing the running belt now the speed light should be flickering if it does then the peed sensor is good if not flickering then replace sensor. If we have a good speed sensor then I would check the Drive Motor this done unplugging the unit the disconnect the two leads coming from the motor to MCB then by using a fully charge 18v drill battery connecting the leads to the motor should move it at approx; 1 mph then Your MCB is defective and need to be replaced. if no belt movement you for the most part will have worn brushes or open windings in the motor , I would open the brush compartment and inspect the brushes if they are less than 3/8" in length replace them this should the motor issue. Good Luck

Testimonial: "very helpful thanks much, JW"
You may have a beltand deck problem. Test by the following procedure:
without the poweron stand on the walking belt, push the belt in the, direction it normally turns. If the belt is very difficult to turn (on most treadmill this means that you have high belt/deck friction I first apply silicone lubricant between the belt & deck to see if that clears up the problem. Most problems originate from the belt and deck 75 to 85% of the time

Yeah - the sensor is the problem... It is magnetic... You can find it next to the wheel on the belt - It is fairly small.... There is a metal disc in the wheell on the belt that is a magnet.. As it passes by the sensor - the sensor registers the magnet and can simply calculate speed based on the frequency of the passes... Sometimes the sensor slides too far back and ergo can`t register the magnet passing by - Then you get the L5 error...
