If the colse buttons make a chirping noise when you push them the console should be Ok. If there is no chirping noise with the push it is a bad console. If everything but the speed works it will probably be your motor controller that is bad.

This definitely sounds like the drive motor. One way to check is to remove the drive belt and run the motor without the walk belt connected. Obviously if you still have the noise it will be a motor issue. If not then it will be one of the 2 rollers. Good Luck! Tim

If the walking belt is off-center, first remove the keyand UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left rear roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left bolt counterclockwise 1/2 of a turn. Be careful not to over tighten the walking belt. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is centered

Troubleshooting: ERR2 - Motor Movement
Since the motor moves when you press speed up, focus on the optic sensor, its wire connections, and the
optic sensor wheel. If all seems well at the sensor, inspect the motor.
??? Optic sensor wheel - Make sure that the optic sensor wheel rotates securely, without wobbling, in the
middle of the optic sensor. Realign and tighten if necessary. If optic sensor wheel teeth are missing or
bent, replace the optic sensor wheel.
??? Optic sensor wires - Make sure that wires are inserted securely to the optic sensor and to the drive board.
Check wire continuity.
??? Optic sensor - Turn on unit power. Turn the motor flywheel with your hand. The optic sensor
indicator (LED10, drive board) should light. . If it does not light, and all parts above are
good, replace the optic sensor.
??? Motor arcing - Does the motor show signs of wear - irregular arcing, carbon dust?
??? Motor brushes - Do brushes show signs of irregular wear - cracks, dents, lines? Replace the
??? M+ M- Wires - Make sure wires are connected properly.
??? Display main IC - To ensure proper signal processing, press down on the main IC on the display
board, marked U5. .
??? Ribbon cable - Ensure that the ribbon cable is attached at the drive and display boards. Check cable
