Chamberlain Liftmaster gate problem CB1
#1
Hi,

I have 2 lyn300k's(230v) controlled by a CB1 control panel. They have been out of action for a while as one of the arms broke. I have now replaced the arm but when i try and set the running time (open-closed potentiometer) the running time does not change and the gates are running passed the point which i need them to go.

Could it be that i have wired the gates up wrong or has this potentiometer broken?

If it has broken and i better off doing a straight replacement or upgrading (if so to which control box - ideally i don't want to have to add any more cables as i'll have to dig up my drive)!!

Thanks for your help.
