I can't get the footrest to move up or down could the control box be bad?
Generally speaking, it could very well be the junction box on your lift chair, but it could also be a motor, or even a cable connection. We are a parts retailer only and we are unable to provide a higher level of technical assistance on this matter. We would recommend reaching out to a lift chair technician to see what part you need. With that being said this particular junction box has been discontinued by the manufacturer and is no longer available.
