My dad is looking at getting a used pellet stove. So far, there are 2 he has seen and asked me about. One is an 06 Castle, not sure of the model, that has a new board, but an overheat issue according to the seller. The other is a Santa Fe the has a blue indicator light, but nothing else is coming on. I told him that I think the Castle model would be the better choice, as it could be nothing more than a limit switch or the board isn't correctly programmed. Here are the links to each stove. Santa Fe Pellet Stove, Castle Pellet Stove. What is everyones thoughts? He is looking to get one of these this Monday.
