This happened the other night while sitting on the couch at the girlfriends place... A loud buzzing sound started eminating from the A/C, ( loud enough the tenants below us heard it) and this was followed by a burning smell. Pulled the plug out of the wall and FINALLY got around to bringing it home and taking it apart today...
Figured "why not" and plugged it in just to see what the problem was exactly , with camera in hand of course, and this is what I found:
That's a great picture! Thanks for sharing it. Investigating something like this in a somewhat safer, more controlled environment can be fun, especially when you can power up from a distance. How much time had elapsed from when you turned it on until that cap blew?
Mike: Originally when it failed it was running for the entire day.. I unplugged it seconds after it started shorting out.. In those pictures though it started to arc as soon as I turned the unit on and probably went for 15-20 seconds before fizzling out, and would do no more than emit smoke whenever the compressor O/L reset itself. It is older too I am assuming its about 15-20 years old (Kenmore) but still works not bad when its not spewing smoke and fire
Steve: Yes it could have been a lot worse but we were lucky there... Didn't have to replace the unit though... Had spare caps of the correct rating lying around. The old heap runs again!
