My proform treadmill goes at one speed and stops when I get on. Have tried speeding up without getting on but stays slow.


Thanks for contacting I understand how frustrating it is having trouble with your treadmill not working properly. We are here to help. Based on the symptom, I suspect there is two problems with the treadmill. The first problem is the belt stopping when walking on the treadmill. When the belt is out of adjustment, the belt can slow down or stop when walking on it. Adjusting the belt as shown on page 23 of the owners manual should solve the problem. The second problem is the speed not increasing. When the speed will not increase, the problem may be a bad controller, the reed sensor need to be adjusted or the treadmill needs to be calibrated.  To calibrate the treadmill, it needs to be in calibration mode. To enter the "Calibration Mode" follow the steps below:

 1   Remove the safety key

 2   Press and hold the Stop and Speed up button

 3   Insert the safety key

 4   Release the Stop and Speed up buttons. The console is now in calibration mode.

While in the Calibration Mode go to the second level by pushing the Speed Up button.

To calibrate the speed, push the Speed Up button until 84% or 85% show in the Calories window of the console. Next, push the Speed Down button until the display shows zero.

To calibrate the incline, just push and hold the incline up button for 2 seconds. The incline should continue to go up and then reverse until the incline is at zero.

Pull out the safety key and reinsert it so the treadmill returns to normal mode. I hope this helps.

Thank you for the question.

I am sorry you are having a problem with removing the hood. I will be able to help you. The treadmill has screws from the bottom that secure the hood. To access the screws you will need to tip the treadmill on to its side. Then use a long screwdriver to reach the screws that are recessed in the bottom panel. The image below shows where some of the screws are located. Once the screws are removed tip the treadmill back up and lift the hood off.

Please let me know if you need further assistance.

Thank you for using Manage my life.
