We have a Healthrider Soft Strider EX softtrack cushioned treadmill

We have a Healthrider Soft Strider EX softtrack cushioned treadmill Model No. J60297634. We turned it on the other day and got error code 21. Can you tell me how to reset this or at least what this code means?
Check the reed sensor also known as the speed sensor. It is located on the front roller pulley. It is mounted to the frame and looks like a small black tube with a wire attached to it. What you need to do is to check if it is good by using an ohm meter.

1. Unplug the reed sensor
2. Place the red and black leads on the two wires
3. turn the flywheel so that the magnet (should be mounted on the pulley)passes by the sensor(make sure the sensor is only 1/8" away)
4. the meter should show the sensor opening and closing if it does not recheck the gap from the magnet and if it is good, replace the reed switch.
5. The other possibility is the magnet fell off the pulley and in this case you will need to superglue it back in place.


Thank you for your question and I hope this helps.

The only thing that we see that sounds like what you are talking about is a little (about an inch and a half diameter) wheel with slotted holes in it on the motor on the opposite end of the flywheel. It passes through what looks like a couple of magnets that are about an eighth of an inch away from the wheel. We dont see anything that looks like a black tube attached to the frame. there's a plug with three wires in it (three pins on the motor side), they are black, red and blue.

Yes that's correct, I was looking at the wrong version of your model. Yours has the slotted wheel. Make sure it is centered, remove any dust or debris that may block the signal and make sure the wheel spins true. If everything looks ok put your safety key on and manually spin the motor. If the sensor is working correctly a light on your motor control board(next to to the motor with the metal frame) should blink. If no light is blinking, replace the sensor. If the light does blink, replace the motor controller.
