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.

Firstly the Liftmaster SCS300 230volt system requires stops when gate is open and closed.So if the gate is travelling past the possition you want this means no stops and this will cause damage to the system.
This will have caused the motors to fail and may have damaged the circuit board. We can still supply replacement CB1 circuit board @ £135+vat and delivery
