Q:

What does an E3 error message mean on my Lifestyler Expanse 2000 treadmill, model 831297280?

A:

The E3 error code on your treadmill is caused from an overspeed condition. The console sensed the motor speed went more than 2 mph faster than it was set for.

This is usually caused by a dry or worn walking belt. The belt creates extra resistance for the motor and the controller sends extra voltage to the motor to compensate. The belt hits a slick spot and the extra voltage causes the motor to overspeed.

To check for wear on the walking belt, lift the belt in the center and feel and look underneath. If the belt is cracked or worn into the cord it needs to be replaced. Check the walking board for wear also.

If the walking belt or board is worn, I suggest you shop for a new treadmill.

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 [www.searspartsdirect.com]. 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.

Q:

I have a treadmill model 831-297280. On start up, the motor speed changes fast, slow, fast from setting for 2 minutes, then it is ok.

A:

The console and the motor controller might need calibration. I am sending you an image of the calibration instructions for the treadmill.

If calibration doesn't solve the problem, the motor controller is probably failing.
