E2 error code how do i fix it

Error code E2 on a treadmill typically indicates a problem with the speed sensor. The speed sensor is a small device that measures the speed of the treadmill belt and sends a signal to the treadmill's control panel. If the sensor is not functioning properly, it can cause the treadmill to display an E2 error and prevent the belt from moving.
There are a few potential causes of an E2 error on a treadmill:

1. The speed sensor may be loose or misaligned. Make sure that the sensor is securely attached to the treadmill frame and properly aligned with the magnet on the flywheel.
2. The speed sensor wire may be damaged. Check the wire for any visible damage, such as fraying or cuts.
3. The control panel may be malfunctioning. If the error persists even after checking the sensor and wire, the control panel itself may be the issue. In this case, it may be necessary to have the treadmill serviced by a professional.

I hope this information is helpful. If you continue to experience problems with your treadmill, it is recommended to have it serviced by a professional to ensure that it is functioning safely and correctly.

Dear Sir:
The error code E1or E2 coming from this reasons.
1) Adjust the speed sensor, see the diagram attached, clean, and tight the connector wires.
2) Test the main motor input voltages coming from the output from the main motor board.
3) The main motor or motor board can be faulty or need repair.
See my personal TIPS for HELP and guide you.

sincerely. God bless you

Dear Sir:

I will try to help you, please be patience and carefully, use basics tools:screwdriver, hex,allen, Dvom.

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

??? 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

??? 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

motor brushes.

??? M+ M- Wires - Make sure wires are connected properly.

Other

??? 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
continuity.

E21or E2 1 means the treadmill is not picking up a speed signal once the start key is pressed. First, determine if the motor is turning before you get the E2 1 or not. If the motor turns, the speed sensor is the most likely problem. If it does not, you can manually turn the belt with your feet before you get the E2 1 and you should get a speed reading but eventually you will get an error code because it is almost impossible to keep the speed constant enough for the computer. Try running it through calibration with the motor cover removed. their is Tech sheet under the hood and it will explain how to do the calibration

Did you find a solution for this issue? I have a similar situation

that the belt is to tati or to lose

I believe E4 on ths 730si means that the speed of the motor the sensor is detecting is greater than the set speed. E2 would be the opposite. I believe there is a way to calibrate the speed. Look at the smaller motor controller board.

Your problem might be that the sensor 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.
