Pro Form 745cs speed control will not hold correct speed

My Pro Form 745cs treadmill will not hold the correct speed. I had to replace the belt. Once I put it all back together, the treadmill maintains a speed faster than the selected speed. It holds approximately 1 mpr faster than selected. I have adjusted the reed switch per the manual instruction, but it still goes too fast. Any ideas?

SOURCE: Pro Form 745cs Treadmill does not incline

My jack screw needed to be adjusted. It is a long screw about 1" in diameter. If you take the cover off, you should clearly see the jack screw. If you adjust the incline with the cover off, you should see the jack screw rotate. One end of the jack screw may have come out allowing the screw to rotate freely and not raise the incline. If you can reengage the screw, it may work. I don't know if this will help, but I needed to do it.

SOURCE: Pro-Form Sport 1000 treadmill does not stop inclining

Do a Calibration on the treadmill. Take out the safety key. With 2 fingers, hold down the stop button and the speed up or spped plus button. keep holding them down as you insert the safety key, then let go of both.
Press the stop button 1 time, you should see all 0's in the windows, or EP 2P or something weird like that.
Press the Incline up button and then wait. If the incline go up until it stalls then down until it stalls the stops at the bottom, the you are recalibrated, take out the safery key and put it back in to see if all is well. If the incline takes off up again without touching a button, the you have wiring problems or control problems. Call service company to get it repaired.

SOURCE: I have a Sears Pro Form 730si. The treadmill

I believe E4 on ths 730si means that the speed of the motor the sensor is detecting is greater than the set speed. E2 would be the opposite. I believe there is a way to calibrate the speed. Look at the smaller motor controller board.

My preform treadmill isn't starting, how do I fix this problem?


If it tries to run for a second or two and stops it will probably be the speed sensor. It is a small magnetic switch that is activated by a magnet on a flywheel that drives the belt. The control board looks for this signal to set the speed of the belt, without the signal the belt will stop. A competent DIYer could probably find and fix it but make sure the machine is unplugged from the wall before attempting any work.

How to reset/recalibrate your treadmill after replacing drive or incline motor,...


Make sure you recalibrate your treadmill after installing ANY controller, motor or console. You can NOT over calibrate your treadmill. You want to make sure you adjust your pedometer for the correct operating speed and incline adjustment. First plug in your treadmill, do not stand on the walking belt. Hold down the "Stop" and "Speed +" key and insert the safety key or magnet, let go of the two keys. Now press "Stop" key once. This puts you into the level 2 of calibration. Press the "Speed +" key slowly until you see 85 on the console, (at this point the display is going to show the percentage of motor usage and also the actual walking belt speed) at 85% motor usage your top speed should be between 10 and 10.5 MPH or (of 12 and 12.5) depending on the treadmill. You must know your treadmills top speed. (Important the motor may be damaged if you set the maximum speed higher than the maximum speed that your treadmill is made for). If the speed is higher than 10.5 or 12.5 then you need to turn the potentiometer down to the correct level. The adjustment is made with a phillips screwdriver, and the adjustment point is on the motor controller. It is a little square metal box with a yellow plastic adjustment screw inside. If the speed it to low you need to turn the potentiometer higher. Once the speed is correct you are done calibrating the speed. Press the (-) speed key to lower the percentage to (0). Next press the incline (+) button, this will make the incline motor go all the way to the maximum incline and come all the way down to the level position. Then remove the safety key and the treadmill will reset into the normal manual mode. Double check that the treadmill is operating at the correct speed and incline motor works correctly, by running maximum settings. Once you are done, be sure your treadmill is properly protected from surges from power spikes that can destroy the work you just performed.

Hope this helped.

My control board does not work...buttons cant be pressed to engage the treadmill? I have a Pro-Form cross walk>


Remove the console from the treadmill and remove the back
remove and replace the ribbon cables that run from the keypads to the control board (they are flat plastic strips that push into the board).
remove and replace all the connections on the console
reattach the console and calibrate by doing the following:
1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2

If the keys will not work then the console is bad and would need replaced.

Pro form 515 changes speeds on its own periodically


It sounds like you have a short circuit in your controller. Unplug the treadmill and remove the motor hood cover. Now find the speed control that gives you the signal from the controller to your motor. Unplug the connector from the controller and replace the motor hood cover. Now plug in the treadmill. If it still speeds up during power up, you have a bad 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.
