One of my 14x dimmers K5002 has some unexpected variation : if the light is dimmed at 70%, it can vary for 3x seconds to 60% and then back to 70% !!!
IC1 and the triac are already replaced but the problem is still there. What do I need to do ?
It’s not a new installation as it runs since many years and this is the only one dimmer wich gives the problem !
Thanks for your help !
If I remember well, one of the caps is at the cause of troubles, most likely C3…
Probably C5 or C6 could be defective, try to replace them.
