It is common to see this error as and L5 error, but it is actually an LS error. The following information will define this error and give you the possible solutions to fix this issue.

LS Error with No Belt Movement on Landice Series Treadmills

LS Error on Landice L-Series Treadmills with No Belt Movement Probable Cause A LS error on the Landice L-Series treadmills can also look like L5 and this error code means there is a loss of speed signal. If this error occurs with no belt movement, the causes for the LS or L5 error are:A) Faulty upper display board or faulty relay board
B) Improper speed control wiring
C) Improper motor control wiring
D) Worn or faulty motor brushes
E) Faulty pwm/relay combo board or faulty drive motor
Corrective Action A) Enter Open Loop Speed mode and set treadmill speed to confirm proper line voltage to pwm board and that the green BELTSW light is lit on the relay board. Replace upper display board or relay board if necessary.
B) Inspect speed control wiring and correct wiring if necessary:

1. Checking purple wire from V+ on pwm board to P3 on the relay board
2. Checking orange wire from P1 on pwm board to P1 on the relay board
3. Checking brown wire from P2 on pwm board to P2 on the relay board
4. Confirm P3 on pmw board has no connection

C) Inspect motor control wiring, checking wires from motor to A+ and A-. Correct wiring if necessary.
D) Inspect motor brushes verifying brushes slide freely, are at least 3/8" long, are curved and have no burns or cracks. Also check the brush springs and verify that the brush copper wire is not burned or broken. Replace both motor brushes if necessary.
E) Inspect motor turns and is not seized up or has a broken shaft. Replace motor if necessary. Also verify at least 90VDC present from the black (A+) wire and white (A-) wire from the pwm board to the drive motor. If voltage is present, replace pwm/relay combo board. If no voltage present, replace drive motor.
Details about LS Error on Landice Series Treadmills with Belt Movement
LS Error on Landice L-Series Treadmills with Belt Movement Probable Cause A LS error on the Landice L-Series treadmills can also look like L5 and this error code means there is a loss of speed signal. This error can occur with belt movement but speed will not increase. Causes for the LS or L5 error with belt movement are:A) Speed sensor is out of adjustment
B) Speed sensor is damaged or faulty
C) Display cable is damaged or faulty
D) Improper speed control wiring Corrective Action A) Speed sensor should sit parallel with the flywheel and gap between speed sensor and flywheel should be within 1/16". Adjust speed sensor if necessary.
B) Inspect speed sensor connector to relay board. Check for pushed pins or loose wires. Repair or replace speed sensor assembly if necessary.
C) Inspect upper harness or display cable connector to relay board. Check for pushed pins or loose wires, giving specific attention to pin 5 (brown) and pin 9 (green). Repair or replace display cable if necessary.
D) Inspect speed control wiring:

1. Checking purple wire from V+ on pwm board to P3 on the relay board
2. Checking orange wire from P1 on pwm board to P1 on the relay board
3. Checking brown wire from P2 on pwm board to P2 on the relay board
4. Confirm P3 on pmw board has no connection

Correct speed control wiring if necessary.

Does the walking belt move for a brief moment, then immediately stop, followed by the E1 code? Or is there no belt movement at all when start is pressed?

Quinton E203 Error, Motor Overcurrent (Overload) Probable Cause 1. Obstruction to motor pulleys or belt
2. Disconnected or loose motor lead
3. User outside the weight/speed envelope.
4. Excessive wear to deck/belt.
5. Motor.
6. Lower Electronics.
Corrective Action Quinton Treadmill Models: Club Track 3.0 and Hyperdrive

1. Inspect for obstruction and remove if necessary.
2. If the motor did not turn, inspect for loose or disconnected motor lead. Reconnect if necessary.
3. Restrict users to weight capacity of unit. Restrict use to people that do not move slower or faster then speed setting.
4. Inspect deck and belt condition. Deck should have a slick smooth surface, free of nicks, grooves, or rough areas. Deck should be flipped or replaced if necessary. Underside of belt should not have a hard glazed appearance. Belt should be replaced when deck is flipped or replaced.
5. Club Track 3.0 models: Remove power and allow unit to cool for 15 minutes. If unit operates and then error appears again, replace drive motor.
   Hyperdrive models: Remove power and wait for high voltage indicator to go out. Check resistance between motor leads. If the reading is greater than 100 ohms, the motor needs replaced.
6. Club Track 3.0 models: Remove power and allow unit to cool for 15 minutes. If error message appears immediately, replace the lower electronics.
   Hyperdrive models: Remove power and wait for high voltage indicator to go out. Check resistance between motor leads. If the reading is less than 100 ohms, replace the lower electronics.

Quinton Treadmill E203 Error Code

L5 or LS is short for Low Speed error

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.

Hope this helps (remember to rate this answer).

Error 1 - Start up error. This is caused because the belt was commanded to move and the opto (speed sensor on the motor) has not seen any movement or the belts movement was interrupted prior to it reaching its commanded speed. To fix Verify opto operation in Diagnostics, Motor Test
Mode, Section 2. Verify DC voltage at connector P6 pins 1 and 2. Verify that LED 4 on the Motor Controller flashes as the motor moves. Let me know if you need any more help. Fitness Fix-It

error 1 simply means no belt movement generally. If belt moves a little it could be the speed sensor but generally it's the motor controller.

LS Error on Landice L-Series Treadmills with Belt Movement Probable Cause A LS error on the Landice L-Series treadmills can also look like L5 and this error code means there is a loss of speed signal.
