arw01 Posted October 18, 2014 Posted October 18, 2014 I flipped the breaker and I don't think my helper was looking at the switches (one brand new dual band dimmer) and then one older dimmer switch. I SAW the second one blow as I boneheaded it and wired the load red to 120v straight from the hot line instead of my load. From the outside I can see I fried at least the voltage regulator. Any else fixed one after the magic smoke is out?
larryllix Posted October 18, 2014 Posted October 18, 2014 Ouch! I have never looked inside one but aren't these units all 0.05" pin spacing and with the leadless solder being promoted today I wouldn't even attempt it.
Brian H Posted October 18, 2014 Posted October 18, 2014 (edited) The internal photos of the 2477D Dual Band show all surface mounted parts. The older power line only ones. Where also almost all surface mounted components. Except a few components like the triac controlling the voltage to the Load. Maybe you blew the triac as it looks like the older leaded voltage regulators. Edited October 18, 2014 by Brian H
arw01 Posted October 19, 2014 Author Posted October 19, 2014 That could be, it's got it's heat sink as the side of the housing and it's a nice burnt up color! Do you suppose it would stop there or get some other pieces between, but likely thinking about it the triac go because they use what an opto issolator most of the time to keep current out of coming in when that blows? The good news is I didn't wire the red led on the 8 button $80 swich when I had that one backwards today, keep thinking my red traveler is a neutral and not a hot when wiring the cans up today. Luckily I noticed my error before I wired the red wire off the switch tonight, fixed my error, still didn't work so checked the switch and I had wisely capped the load wire along. Hooked it up and walla dimming lights!
