Recently I have been noticing a crack in my speakers when my refrigerator kicks on to cool. I live in an apartment and within days of moving in noticed that the lights dimmed when the fridge kicked on, so I decided to investigate. I found out that my entire living room, dining room, and kitchen (including fridge and dishwasher) are run on one 20-amp circuit. The crackling has been recent and it seems to only do it if the fridge kicks on. I am worried that the shotty wiring may destroy my speakers and am trying to find a solution. My apartment place seemingly won't do anything about the wiring as they claim it is "ok". I know the fridge should technically be run on it's own circuit, but I don't forsee them fixing this problem unless I were to get the code enforcement officer for the local municipality involved. I was told that a power conditioner may do the trick but really don't want to spend that kind of money. Anyone have any thoughts?
