1. The circuit board is aging. When running for a long time, the circuit board may age, leading to failure.
2. The circuit board is burnt out. Some users use the treadmill for a long time, and the motor of the treadmill is overheated, causing the circuit board to burn out.
3. The treadmill power supply is unstable. Treadmill needs a stable power supply. If the power supply is unstable, the circuit board will be damaged.
4. The treadmill is abnormal during use. For example, the treadmill suddenly stops during the movement and the speed is unstable, which may lead to the failure of the circuit board.
When the treadmill has e2 fault, it can be eliminated by the following methods:
1. Check whether the power connection of the treadmill is normal, especially whether the three-pin plug is in good contact.
2. Check the fuse of the treadmill to see if it is blown. If it burns out, it needs to be replaced.
3. Disassemble the treadmill and check whether the circuit board is obviously damaged or burnt.
4. Clean the dust inside the motor and keep the heat dissipation of the motor.
5. Check whether there are other external factors that interfere with the work of the treadmill, such as things getting stuck.
6. If the above methods can't eliminate the e2 fault, it is recommended to contact the after-sales service center for maintenance.
To sum up, the fault of e2 is the circuit board fault of the treadmill, which can be eliminated by checking the power supply and fuse. If the problem cannot be solved, you need to contact the after-sales service center for maintenance in time. At the same time, regular maintenance of treadmills is also an important way to prevent treadmills from breaking down.
