| Our new and improved troubleshooting section was carefully constructed to put the power to repair your machine in your hands. As you can tell, we have put a great deal of time, effort and detail into making the process easy to understand for a wide variety of individuals. All of this can save you the cost of a service call which is approaching $150 in many markets and in many cases, we can save you the cost of parts since many parts are sold from factories unnecessarily (many parts cost over $100 alone). That being said, we hope that you find this troubleshooting area helpful. Should you find that our troubleshooting tips help you out, please donate to keep this info on the web. We have been informed by a number of our users that they feel that donating 10% of the cost of what they feel our troubleshooting tips saved them seems appropriate. However any donation is welcomed and appreciated. As donations come in we will continue to add to this area of the site in an effort to make your ownership of fitness equipment an enjoyable one. One of the first areas we would like to begin updating is the addition of video posts as a tool to assist our user community. If this info helps you, please click on the donate button and donate to help us expand and maintain our troubleshooting help. Please note that donations, while appreciated, are NOT tax deductable. |

FULL SPEED UPON POWER UP
This condition is when the treadmill goes to full speed as soon as you power up the treadmill. Typically when this occurs, it is an indication of a short circuit in the motor controller. To test to make sure the problem is in the motor controller, perform the following steps (this test only works on treadmills with simple SCR controllers like a MC-60...if you have a digital treadmill or a more complex treadmill skip to the second test section):
First Test Section
1) Unplug the treadmill from the wall.
2) Remove the motor hood.
3) Unplug the speed wires from the controller. On many controllers, you will have 2 to 3 wires that control speed and many are labeled H, W, and L. If you cannot find the speed wires, do not guess, contact us with your make and model number and we will try to help you with the wiring.
4) Return the treadmill to a usable position once the speed wires are disconnected and plug the treadmill back in.
5) If the treadmill begins to run at full speed, the motor control has failed and requires replacement.
6) If the treadmill does not run at full speed you could have a speed input problem, wiring problem, or another short circuit.
Second Test Section
1. Unplug your treadmill from the wall.
2. Remove the motor hood.
3. Check and see if your controller has three speed wires labeled H, W, and L or a unified wiring harness labeled H, W, and L from the console. If not, you have a digital controller and full speed upon power up is always a failed controller. No need for further testing...you need to replace the controller.
