I have a 2477D Dimmer in my kitchen. This unit controls ten (10) can lights (all LED R20 type Dimmable) in the kitchen ceiling. It has been working fine for many years. Yesterday, one of the lights started flickering (I thought it was just one) but then several more started flickering. Then the 2477D started acting erratically. Now, sometimes when I press it, the small LEDs on the unit light from bottom to top, as they normally do at the lights brighten. But all the LEDs are flickering like a deranged disco! And if I turn the 2477D OFF, the bottom LED is flickering and the unit no longer works. If I wait a few minutes, it might work again but the can lights always flicker.
So, I am guessing:
So, basic question are:
So, I am guessing:
- One (or more) of the R20 LED lamps are going bad
- The 2477D is going bad.
So, basic question are:
- Does anyone have experience with sudden onset of flickering LED lamps on a previously good running system?
- Should I replace the 2477D with a spare 2477D "earmarked" for another project that I can use to replace this 2477D? (but don't want to go through the hassle of that unless I have to...)
- Should I replace some or all of the R20 LED lamps in the fixtures?
