the treadmill goes up and wont come down? We read the manuel and did the troubleshooting. Not sure if there is a problem with the 6 cin connector
unpluged the treadmill and took off the cover and unpluges that also
It sounds like it may have gotten out of calibration. If the following steps are to hard you may need a tech to come out to your house to do it.Calibrate the elevation potentiometer: 1. Visually confirm treadmill is level. Press down arrow for elevation till machine is level. 2. The potentiometer should read 0.1 ohm for all models. NOTE: Elevation window shows actual elevation. Display shows potentiometer setting. 3. If the setting is incorrect, follow the steps below. STEP 1: Turn the post of the potentiometer all the way CLOCKWISE STEP 2: Slowly turn the potentiometer COUNTER CLOCKWISE until the setting is correct. (NOTE:If the setting seems stuck at 25.5 ohm check that pot wires are seated in the correct order and that upper wire harness connection is seated tightly.) 4. Carefully install potentiometer into the motor housing. *NOTE: The setting may vary when inserting the potentiometer into the motor. As long as the change is minimal, fine adjustment can achieved after the potentiometer is secured into the motor housing. 5. Press OFF to turn treadmill off.Ultimately unless there is a wire broken in the harness or a bad connection the motor itself is the issue and if calibrating doesn't work the potentiometer or whole motor may need replaced.
I'm pretty sure it a bad connection in the 6 prong connector. If I press it down the green light on top of the board goes of and it works fine. But the next day when I turn it on it just raises up and san sticks at the highest level, I can't get it to come down unless I disconnect that connection and replug it in and press it down with my finger. Do you think it's the connector??
Yes it sounds like it. Possibly a bad solder connection to the board.
what do you recomend?
I would see if when you move the connector if you can see any of the solder lifting or moving. If not, I woudl get a tech out there to look at it and possibly fix the connection. If you can see where it is broke you can add a little solder and remelt the old to fix the issue. You would need a soldering iron to do it though.
