Electrical Wiring in the Home/Dimmer Switch - Light

Question
Hi Bob,

We replaced an original light fixture in our kitchen 6 years ago (with a Hampton Bay Ceiling Wave Bar light); soon after, I installed a dimmer switch. The light has functioned properly until recently.  Now, when we turn on the light (dimmer all the way up), we're only getting 40% light.  I've replaced bulbs on the light itself so I don't think it's the fixture.  My guess is that the dimmer isn't working well anymore.  Checked the circuit box, reset, etc. but no change.  

Does this sound like a dimmer issue?  Do I need an electrician?  I can replace the dimmer and will, but wanted some advice before proceeding.  

Thank you,
Len

Answer
Assuming you did not change the bulbs to CFLs or LEDs, it is probably the dimmer.  They are very fragile, and are easily damaged.  You can either replace the dimmer with another dimmer or with a plain switch temporarily to see if it works.  If a plain switch works, then the dimmer was bad.  Make sure you turn the power off at the breaker box when you replace the dimmer, or you will damage the new one (and get a shock).
