You will need to check the speed sensor for proper alignment and function. it should be located near the front roller or mounted on the motor. It should be within a credit cards width of the magnet or toothed wheel. If properly adjusted check with an ammeter to see if it is opening and closing by manually spinning the front roller or motor flywheel. If it isn't replace the sensor. If it is functioning make sure you are getting 5vdc to it across the wires. If you are not replace the upper control board(console). If you are getting the proper voltage then replace the lower control board(motor controller).

The motor controller weakens over time because of the excessive amperage draw of the motor do to lack of lubrication (which wears the walk belt and walking deck).

Take an amperage reading of the motor it should be 2-3 amps with no one on it, with someone walking on it it should be around 6-12 amps. I would bet yours is elevated above 6-12 amps.The controller is dropping output because of the friction problem.

The first thing to try after testing the amperage is to lubricate the walking platform. Then retest and see if the amperage comes down and it doesn't shut off.

If it does then the next step would be to replace the walking deck. If the amperage still is up you may need to replace the walk belt second and finally if after replacing the deck and belt, if the unit is still shutting down replace the motor controller.

Your problem might be that a magnet has fallen off. Here's an illustrated guide that should make fixing it easy: http://fixmytreadmill.blogspot.com/2010/10/how-to-fix-treadmill-e1-error.html

Good luck.

Hi,

The E1 error message. This is due to the fuse having to be switched from the 2.5 amp to a 3.5 amp. they did not recall the machine because of the low cost $2.99.

The Fuse is Located on the Board itself.

I guess the Part Number for your model is 000182177.
