My heater went out a couple of years ago, I have a plan through my electric company which if something breaks the electric company will send someone out to fix it at no charge. The repair to my heater would have cost about $500USD. My obvious question is does your electric company offer anything like that? If they do and you get on that type of plan they probably won't cover it since it already broke before you signed up, but they may fix it for a fee which is still better than replacing the whole system. It is a long shot, but what the heck I don't see where you have anything to lose. Hope this helps.
