Re: Err LS on Bowflex Treadmill
The machine needs to be re-callibrated. L5 error.
Your speed sensor must have been damaged either during shipping or use. You'll need a new one. If under warranty - give Bowflex a call. They will ship you out a new sensor and guide you through installing it via the phone... re-calibrating the machine... and getting it operational again. It will take about 2 hours.
The instruction book doesn't mention calibration. be sure to not callibrate in metrics, however (there's no way to easily tell the difference - you have to ask) or you'll be strolling like a walk in the park at 5 "mph".

If you're running the machine on a dedicated circuit then your unit is drawing too much current. This can be caused by friction and drag. Solution: Lube deck/belt. If problem persists, replace deck/belt. If you ignore this fix this will blow your controller. .
follow this steps and fix it. God bless you Plug Treadmill into wall outlet and press START. Display lights up; TREADBELT DOES NOT MOVE "L5 / LS ERROR" Is red SERIAL lamp on the motor control board lit? Is the yellow RLC lamp on the motor control board lit? 1. Unplug the treadmill from its 2. Wl alk on the belt manually. (push belt) 3. Does the yellow MOTOR lamp light while pushing? Is yellow MOTOR lamp on the motor control board lit? 1. Loose wire connection to motor, capacitor, or choke. 2. Loose brush holder screw on motor. (Check Both) 3. Failed drive motor. Part # 70014 (110V), 70125 (220V) NO YES NO YES 5.1 5.2 5.3 5.4 5.5 NO 1. Check wiring harness connection between upper and lower board. Part # 70083 2. Replace display board. Part # 70076 YES Enter Open Loop Speed mode: WARNING: NEVER STAND ON THE TREADBELT IN THIS MODE. 1. Turn off the treadmill. 2. Press FAST and START simultaneously and release both buttons once the display lights up. 3. Hold the fast button until the display reads 99. Short in capacitor, motor, or motor control board. NO Turn treadmill off. Disconnect drive motor wires from lower control board (Mtr + and Mtr -) terminals. Power up in OLS mode (FAST & START). Bring displayed speed up to 99. Measure across the Mtr + and Mtr - terminals with your voltmeter (DCVolts). You should measure at least 90 vdc on a 110V treadmill and 180 vdc on a 220V treadmill. If you are not getting dc volts out of the lower board, replace it. If you are measuring the proper dc voltage out, replace the drive motor.
It basically means that the speed sensor is not picking up a signal. Unfortunatley its a pretty vague error code and can be caused by several different problems.
First you have to determine wether or not you have belt movement. If you have a LS with belt movement you know that it is related to the speed sensor itself (or the MCB motor control board - the part of the MCB that handles speed sensing function). If you are getting an LS w/belt movement you have to check to see if you have power output from the MCB. If you have no power output, check fuses, if fuses are good you will need the MCB replaced.
This is a LS or speed sensor error, it can be caused by a belt that is too tight, non lubricated walking belt and or a bad sensor. If the belt does not move at all, Bowflex will tell you to buy a new lower control board. $227 direct from them (Nautilus)
Did you try it before you bought it and it was working. when you move the unit and pluged it into the wall outlet was it on? if yes then you may have damaged the lower board. If you can not get that part then the treadmill has died. Is it a Bowflex or a Free spirit.
