This happened to mine and I figured out that the sensors were dirty. I got some canned air that you spray on computers and sprayed out the mother board. I also sprayed the electrical contacts with electrical contact cleaner and the treadmill is a good as new.

Your L7 error looks like L5 , but its really LS which mean lost signal. Unplug unit take motor shroud off then plug unit back in wall outlet. When looking in front unit you will see a Motor control board and there are LED lit up one of them should be an amber light this is you speed sensor which is attached to the top of your motor. Manually rotate the fly wheel and see if that light flickers if it does then your speed sensor is working properly if not replace speed sensor. The next thing to look at is the motor brushes to if they are worn unplug unit you should see slitted caps on both side of motor remove them if they are less than 3/8" they need replacing. That for the most parts should take of your problem. Call Landice @ 1800-526-3423 have the serial# handy their on all the components in the unit

Loss signal or No Speed: 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
