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.

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.

that is a loss of speed error. you only get rid of it when the belt starts moving again

BOB MARLIN SAYS NO

this a problem in 2 ways:
1) test the input voltage motor, if there are the motor need repair.

2) test the output voltage board, for input voltage motor, if there are NOT the board is faulty.

see the block diagram atached.

It is either the control board or the overlay. I would think it is probably the start button on the overlay that is stuck. The solution is to replace the overlay.

I've definitely never seen "P4" on a Landice before so I'm not entirely sure on that one. The other issues seem like they might be associated with stuck keys on the console. It's a very common problem if you have it in a humid area and/or it gets sweat on it during the work out. Being that it's a Landice, you should have a part warranty on it. Have you contacted them?
