I have some recessed lighting in my home that I recently bought in September. The lights are on a dimmer switch. The lights sometimes just go off. Usually when I turn the dimmer off and then turn it back on, the lights go back on. It's an annoyance. I was wondering if this is common when a dimmer switch goes bad and if it's likely this will be fixed by replacing the dimmer. Or do you think this is more serious and I should contact an electrician? Any thoughts are appreciated.
