I have a Powerobics XT450 treadmill which slowly gets faster as you use it. It has a speed controller board with 1090NDRV SPORTS ART 97/04/25 marked in it.

Can it be repaired or do I have to replace the controller board

SOURCE: replaced the motor controls

Is there a sheet of paper under the motor hood? It has the procedures for this calibration of the motor speed. Caution ! You should use a plastic screwdriver to make adjustment to the speed control on the motor controller. It is high voltage

SOURCE: Running belt slips om treadmill Sports Art 1060

Either the belt has stretched (normal wear over time) or the tension needs to be readjusted to tighten it. Every treadmill is different, and some can't be adjusted, so I can't really help with particulars, but if you get down and look really carefully, you'll be able to find the tension adjustment mechanism if it exists. Good Luck.

SOURCE: Athlon iQ2 treadmill-just replaced motor control

If this is the same problem you had prior to replacing the MCB and speed sensor. I would check the drive motor, unplug unit then remove motor shroud then unplug the connectors leading to the motor itself. If you have wire leads and a 18v drill battery connect the leads into motor then attach the other end to you battery and if the motor will rotate ( approx. 1mph) , if it does the check speed sensor to see if the correct spacing between sensor and front roller ( check if the magnet has not fallen out of front roller pulley this also can cause you problems) hope this help!!

SOURCE: I have a MC2100-12A motor

The speed sensor on these machines have nothing to do with controlling the speed. The machine will run without it. The sensor is obviously working, since you are getting a speed reading.
The calibration is a mechanical adjustment found on the motor controller, the instructions are found under the lid as well as the meaning of the LEDs flashes on the tech sheet..
Follow the calibration procedure. If the operation is still erratic, I would suspect a defective controller.
Calibration: Press stop and speed up. Install the safety key/magnet. release the buttons. Press stop 1 time. one window displays speed, the other the calibration number. Both should be "0".
Press speed up, the treadmill should begin to move around 25-30. increase to 85, the machine should be a max speed. adjust the pot on the motor board to max speed. Some machines are 10mph, others 12mph. The tech sheet will tell you the max speed. When adjusted, press speed down. the machine will stop. Now press incline up. That will calibrate the incline. When completed, remove the safety key.
If operation is still erratic, change the motor controller.. It could be the console, but the cost of replacement makes the repair in most cases uneconomical..

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.

Sports art model 1050L give me err 1 how I can fix this problem? Thanks


Reason number 1:
Explanation for ERR1 1. Motor doesn't operate; ERR1 appears. 1-1. Explanation: Drive board has not sent power to the motor, so the motor doesn't operate; the optic sensor signal hasn't returned to the display board. This is caused by either a bad mcb or a faulty motor.

Reason number 2;
Reason for ERR1 2. Motor operates; ERR1 appears 2-1. Explanation: The motor operates; the optic sensor signal didn't reach the display board CPU; ERR 1 appears. In this case the issue is more than likely a faulty speed sensor or a there is dirt, lint or other debris blocking the speed sensor from reading the disc.

Pro form sport 1000 treadmill goes full speed on power up


Typically when this occurs, it is an indication of a short circuit in the motor controller board. To test to make sure the problem is in the board


1) Unplug the treadmill from the wall.

2) Remove the motor hood.

3) Unplug the speed wires from the board. On many boards, you will have 2 to 3 wires that control speed and many are labeled H, W, and L. If you cannot find the speed wires, do not guess, contact us with your make and model number and we will try to help you with the wiring.

4) Return the treadmill to a usable position once the speed wires are disconnected and plug the treadmill back in.

5) If the treadmill begins to run at full speed, the motor control has failed and requires replacement.

6) If the treadmill does not run at full speed you could have a speed input problem, wiring problem, or another short circuit.

How can fix my healthstream LS720T treadmill? my healthstream LS720T treadmill after i turn it on it slowly run then it will go faster then stop and will indicate error message E1, what is wrong with it?


You will need to check the speed sensor for proper alignment and function. it should be located near the front roller or mounted on the motor. It should be within a credit cards width of the magnet or toothed wheel. If properly adjusted check with an ammeter to see if it is opening and closing by manually spinning the front roller or motor flywheel. If it isn't replace the sensor. If it is functioning make sure you are getting 5vdc to it across the wires. If you are not replace the upper control board(console). If you are getting the proper voltage then replace the lower control board(motor controller).

Landice treadmill 05 error code comes on when i hit start


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.
