Error 3 & 6 on minivator lift chair?

Havn't got a clue, But it is very basic unit, What does it not do that it used to do. You say one error id is footrest, but what does it not do. If not lift, motor, gears stiff linkage etc, might just need a spot of grease, Think that way, instead of error numbers, you may be able to figure it out, But post again, giving the codes, but also the problem, someone, like me, might be able to point you in the correct direction, With out knowing the unit
