I am looking at an electrolux frig, apparently it has a leak in condenser. I don't replace freon, and I see frig has a replacement kit for the condenser. Do know someone who has license to replace freon, but with condenser being bad it would have to be replaced before freon is reinstalled in system, and I believe it would be beneficial to replace filter drier. I am assuming it has to be soldered in or brazed. May have to forget about this one. Any advice. Thanks!
