These units only have a calibration mode. The High end units generally will have that. If this is a Epic Then this calibration procedure should work.
Press the Stop and the Speed Up keys down while inserting the safety key. Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test. Press either incline key and the incline will calibrate automatically. BE CAREFUL, THE TREADMILL WILL RUN AT FULL SPEED IN THIS NEXT MODE! DO NOT STAND ON THE WALKING BELT. Press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window). If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled. The max speed potentiometer is a small square with a movable center and is located near the three small speed wire connections labeled H, W, & L and is on the same edge of the board and the red and black motor wires are located. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments. It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure. THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED. After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing. Press the Stop key once and remove the safety key.

Dear Sir:

This problem is frequently.
1) Check the breaker from your home and reset.
2)Inspect the wires from your outlet in the wall and tight it.
3)Do not use any extension cord!
4)Examine the power cord and see if some wires is loose and tight it.

6)Reset the c. breaker internal from the treadmill.
7) Inspect any wires loose and tight it.
8)Lubricates the treadmill between deck vs walk belt, this can cause to shut down the treadmill, since the complex electronic is designed for to protect the electronic components.
9) Lubricate the treadmill in according with your manual instructions.
10) The ball bearing from motor can be faulty+ball bearing from roller deck.
11) The main motor board can be faulty. ( this is last step)
