The optic sensor is located on the rear of the motor. It is a small sensor that senses the speed of an optic disc that mounts on the rear shaft of the motor.

Q:

Treadmill reads E21

A:

Thank you for your question on the Error code on the treadmill.

The E-21 error code appears when the console does not receive a speed sensor signal when it is expecting to (speed is set higher than 0.0 MPH). If the belt moved slightly prior to the error appearing, the cause is with the sensor, positioning of the sensor, or the wiring from the sensor to the console. If the motor did not move at all prior to the error appearing, check the motor, controller, wiring connecting the console, power board, and controller.

The speed sensor is on opposite end of the motor from the drive belt. Also check to make sure the optic disk is not scrubbing the sensor optics.

Please look at these locations and tell me what you find out.

Q:

Can wlak on treadmill but stops when you run it over 5 mph gets an E-22 error message 831297871

A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. I do not think the problem is with the sensor. The reason is the error you are getting is an over speed error. A few thinks will cause this error code. The first is a dry walking belt. If the belt is dry, the control will try to compensate for this and cause the belt to go faster. 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 to 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 [ Sears parts direct | Sears Parts Direct . 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, 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.

If you still get the error code, the problem could be the walking belt is too tight or the person using the treadmill exceeds the weight limit of the unit. The weight limit for this treadmill is 250 pounds. If you need to loosen the belt, the instructions are listed in the image below. Just click on the image to enlarge it.
