Question about Exercise & Fitness
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?

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.

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.

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.
