I've just had someone in for yearly maintenance on my furnace - a KeepRite DC90. The guy discovered a popped ring in the heat exchange and told me that this was pretty common with this model.
I'm just wondering the validity of this statement, since I'm not able to find a single scrap of information in Google groups or on the web itself regarding this issue.
I've been told that the repair will cost $500 and due to regulation/law, the gas will not be turned back onto the furnace until the repair is complete.. I'm really just looking for any information I can get my hands on at this point.
Thanks in advance!
