What to do when the electric wheelchair controller is damaged?
As an important auxiliary tool for people with limited mobility, the stability and reliability of the controller of the electric wheelchair are crucial. When the electric wheelchair controller is damaged, the user may feel helpless, but here are some steps and suggestions to help the user deal with this situation.

1. Initial inspection and diagnosis
Before any repairs, some basic inspections and diagnostics should be performed first. This includes:

Check the power supply: Make sure the battery is fully charged and connected correctly. Check whether the fuse or overload protection switch on the battery box is blown or tripped. If there is a problem, replace the fuse or reset the switch

Basic function test: Try to use different function buttons or joysticks on the controller to observe whether the wheelchair has any response, such as whether it can start, accelerate, turn or brake normally. Check whether there is an error code prompt on the controller display panel, and find the corresponding error code meaning according to the manual to determine the type of fault

Hardware inspection: Check whether the wiring between the controller and the motor is loose or damaged, including key components such as the Hall sensor circuit. Observe the appearance of the controller for obvious damage

2. Common troubleshooting
Abnormal controller indicator light: If the indicator light on the controller flashes abnormally, it may be that the battery needs to be charged or there is a problem with the battery connection. Check the battery connection and try to charge the battery

Motor circuit problem: If the controller indicator light shows a possible connection problem for a specific motor circuit, check the motor connection to see if there is a break or short circuit

3. Professional repair service
If the above preliminary inspection and diagnosis fail to solve the problem, or the fault involves more complex electronic components, it is recommended to contact a professional repair service. Here are some suggestions:

Contact the manufacturer or seller: If the electric wheelchair is still within the warranty period, any fault should first be contacted by the manufacturer or seller for repair, because improper operation may cause greater damage and may even affect the safety of the user

Find a professional repairer: For wheelchairs that are out of warranty or warranty coverage, you can find a professional electric wheelchair repair service. Professional repairers can accurately diagnose the problem and provide repair and replacement parts services

4. Repair case reference
In some cases, the damage to the controller may be due to loose or damaged electronic components. For example, there are cases that show that the controller failure can be repaired by re-soldering loose electronic components or replacing damaged chips. However, these operations require professional skills and equipment, and non-professionals are not recommended to try them on their own.

5. Precautions
To reduce the risk of controller damage, the following precautions can be taken:

Regularly check and maintain the electric wheelchair, especially the controller and motor connection lines.
Avoid using the electric wheelchair in bad weather conditions to reduce the risk of the controller getting wet or damaged.
Follow the instructions for use of the electric wheelchair, operate the controller correctly, and avoid damage caused by improper operation.
In summary, when the electric wheelchair controller is damaged, the user should first perform basic inspections and diagnoses, and then decide whether to handle it by themselves or seek professional help based on the complexity of the fault. It is always recommended to prioritize safety and professionalism and avoid handling complex faults that may cause safety risks on your own.
