Easy to install

November 21, 2021|None, Newberg, Oregon

Tried to do calibration per instructions but my display mph did not show anything. The phillips screw to adjust is basically flat such that even a control size driver did not turn it easily. My mph does seem to work but blanks after a short time and displays correctly each time the speed changes. I am guessing it could now be my circuit board under the display.

Almost a perfect replacement

September 05, 2022|MoralesSSBN628SSN638SJB77, California

I was replacing the original Motor Controller board (uncontrollable speed). The installation instructions were easy to follow. I suggest you get some small cable zip ties before you start. I had to clip a few cable ties to allow cable movement & used cable zip ties to rebundle the wires when finished. Calibrating the speed instructions didn't seem to work well. I could not get the speed between 9.7 & 10.3 mph using the speed potentiometer. Oh well, I don't walk that fast anyway. It seemed to be fine at 3 to 4 mph. I'll try the Owner's Manual (Pro Form CX 18i) calibration instructions next. It seems slightly different.

Disappointed

April 08, 2025|Disappointed, Edmond, Oklahoma

Sears Direct sent me the wrong part 3 times. Furthermore it was difficult to speadl with a live person because they want you to use their website, which is not user friendly. When you manage to speak to a live person they have a foreign accent that is difficult to understand. There is no American.speaking person.
