How often should the electric wheelchair controller be checked?
As the “heart” of the wheelchair, the performance of the electric wheelchair controller is directly related to the safety of the wheelchair’s operation and its service life. Therefore, it is crucial to regularly check and maintain the controller. The following are some suggestions and guidance on the inspection cycle of the electric wheelchair controller.

1. The importance of the inspection cycle
According to MAIGOO knowledge, the service life of an electric wheelchair mainly depends on the life of the controller, motor and battery, as well as the use and maintenance. Therefore, regular inspection of the controller is the key to ensuring the long-term and stable operation of the wheelchair. Although the specific inspection cycle may vary for different brands and models of wheelchairs, it is generally recommended to perform a comprehensive inspection and maintenance at least once every six months.

2. Inspection content
When checking the controller, focus on the following aspects:

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 if 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 fault type

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 whether the appearance of the controller is obviously damaged or worn

3. Daily maintenance
In addition to regular inspections, daily maintenance is also essential. The controller panel should be avoided from being touched by hard or sharp objects to prevent damage to the waterproof layer. At the same time, when operating the controller, you should avoid excessive force or rapid and frequent pushing and pulling of the control lever to avoid causing the controller control lever to drift and cause directional failure

4. Professional advice
If any abnormality is found in the controller during use, such as flashing indicator lights, sound prompts, or abnormal operation reactions, it is recommended to stop using it immediately and contact professional maintenance personnel for inspection and repair. Disassembling the controller by yourself or trying to repair it may cause greater damage.

5. Conclusion
In summary, the inspection cycle of the electric wheelchair controller is recommended to be at least once every six months, but the specific inspection and maintenance should be adjusted according to the frequency of use and use environment of the wheelchair. Proper maintenance and inspection can not only extend the service life of the controller, but also ensure the safety and comfort of the user. Therefore, regular inspection and maintenance of electric wheelchair controllers is a responsibility that every wheelchair user cannot ignore.
