Mutual-aid electric wheelchair can only rotate in circles and cannot move forward.

According to the family doctor's online inquiry, the mutual help electric wheelchair can only rotate in circles and cannot move forward for the following reasons:

1. controller failure: the controller is the core component of the electric wheelchair, which controls the work of the motor, battery and joystick. If the controller fails, the electric wheelchair may not operate normally. You can check whether the indicator light of the controller is normal, whether there are burnt or loose lines, whether there is water or foreign objects entering, and so on. If there is any problem, you can contact the manufacturer or professional maintenance personnel for repair or replacement.

2. Motor failure: The motor is the power source of the electric wheelchair and drives the wheels to rotate. If the motor fails, it may cause the electric wheelchair to fail to operate or only turn around. You can check whether the working sound of the motor is normal, whether there is abnormal sound or jamming, whether there is burning or oil leakage, and whether there is looseness or disconnection. If there is any problem, you can contact the manufacturer or professional maintenance personnel for repair or replacement.

3. Joystick failure: Joystick is the operating part of the electric wheelchair, which controls the direction and speed of the electric wheelchair by pushing and pulling in different directions. If the joystick fails, it may cause the electric wheelchair not to run as you wish. You can check whether the joystick is sensitive, stuck or loose, and whether water or foreign objects enter. If there is any problem, you can contact the manufacturer or professional maintenance personnel for repair or replacement.

4. Wheel failure: The wheel is the supporting part of the electric wheelchair and bears the weight of the electric wheelchair and the user. If the wheel breaks down, the electric wheelchair may not be able to run smoothly or can only turn around. You can check whether the wheels are complete, worn or deformed, loose or stuck, etc. If there is any problem, you can contact the manufacturer or professional maintenance personnel for repair or replacement.
