Question and Answers


I have a pro form 630ds. It shuts off while I'm walking on it. It throws the breaker.


I am assuming the treadmill trips the breaker on the treadmill. If this is the case several things can cause it.

You might have a weak circuit breaker. Replacing the circuit breaker might cure the problem.

If you are using an extension cord on the treadmill, try moving the treadmill and connecting it to a wall outlet. The extension cord might not be heavy enough for the treadmill.

If the walking belt on the treadmill is dry and needs lubrication, it will cause the drive motor to draw excessive amps. To test the walking belt lubrication, do not turn the treadmill motor on. Set the elevation to the highest level. Stand near the front of the walking belt. Push yourself firmly toward the rear of the treadmill. If the belt is properly lubricated the belt will take you to the rear edge of the treadmill and dump you off on the floor. If you move and stop, the belt needs lubricating.

The part number for the belt lubrication kit is 219168. You can buy it at []. The cost is around $4.00. The application instructions should be in the package, but in case they are not here is how to apply the lubrication.

Turn the walking belt until the belt seam is along the top of the front roller. Raise the belt on one side in the center of the walking board front to back as high as you can. Apply ½ the tube of lubrication to the walking board in a zig zag fashion moving from front to back. Move the belt until the seam comes up on top of the rear roller and lift the belt again and put the rest of the lubrication on the walking board in the same manner. Turn the treadmill on and walk on the belt for 10-20 minutes. Walk all over the belt to distribute the lubrication evenly on the walking belt and board.
