First screen shows any error number? for what you describe I think it is simply speed sensor, try to check the cables leading to the sensor card. and then checks whether the sensor is aligned correctly.
Check speed sensor alignment.
It should be within 1/16" of the flywheel
and parallel to the flywheel.
Is it out of position?

OS or O5 Error on Landice L-Series Treadmills


Probable Cause

An OS or O5 error on the Landice L-Series treadmills, such as the L7, L8 and L9, indicates an over speed condition and this occurs when the actual speed of the running belt is faster than the set speed. The possible causes for an overspeed, OS or O5, error are: A) User weight is over 200lbs, treadmill elevation is set between 10% and 15% grade and speed is set between .5 mph and 3 mph
B) User is pushing against treadmill belt causing it to go faster than the set speed
C) Defective lower board or misaligned speed sensor
D) Maladjusted speed potentiometer

Corrective Action

A) Gravitational force will enable the user's weight to move the treadbelt faster than the set speed. The speed sensor will pick up this increase in flywheel speed and sends this information up to the display electronics. The microprocessor will then compare the actual speed to the displayed speed, determine a runaway speed condition and shut the treadmill down. An overspeed will display in the window. This is a safety feature built into all treadmills that utilize closed loop speed circuitry. The way to address an over speed condition due to gravity is have the user decrease elevation below 10% or increase the speed.

B) Similar to the gravitational force, a user can be holding onto the handrails and pushing the running belt in such a manner where they are using the treadmill like a manual machine rather than a motorized one. User needs to set speed compatible for their actual walking or jogging speed so they are not pushing the belt.

C) It's possible a blown motor control board is the problem. This occurs more frequently with PWM drives than SCR drives. However, this problem is becoming rare due to the PWM circuitry which senses this condition and shuts itself down before the drive motor receives any DC voltage at all. This means you'll get an LS or L5 error if your PWM is blown, not an OS or O5 error. This is a safety feature on all Landice home treadmills with PWM motor control boards. The SCR motor control boards also have internal protection to prevent an over speed condition from occuring due to an internal component failure. In the rarest of cases, on home treadmills, a faulty relay board can cause an OS or O5. To verify this, using a digital voltmeter, with treadmill turned on, measure the DC voltage between the V+ and P1 on the PWM board. The reading should be between 6-7 VDC. Also measure the DC voltage between P1 and P2 on the PWM board. The reading should be between 0.5 VDC and 6-7 VDC. If either of these voltages measure zero, replace the relay board.

D) Get into Open Loop Speed mode and check the speed. Adjust pots as necessary to bring up correct speed for max and min.

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

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.

When I turn on I get an overspeed error and machine shuts off. If I start it at a faster speed the speed fluctuates. I pressed start and menu and the LED says 3.5 but the diagnostic reads 6.8


Your speed sensor is not working properly this part is located under the motor shroud and on top of drive motor it is attached to a bracket with 2 bolts. Unplug the unit and remove motor shroud see if you can adjust it first by loosen the 2 nuts and moving the sensor forward without making contact to the flywheel, then tightened the nuts up. Plug the unit into the outlet, start the unit, if you still have the overspeed then replacement of the sensor is needed. Call Landice Directly they will ask for model and serial number and they will the new sensor.

Belt does not move panel lights up


Does your L7 have error code that 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

Landice won't start, it gives a L 5 error. I already replaced both chip boards. but the light on the board closest to the motor does not come on! Not sure if I got a faulty board? Is there any information...


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.
