Ok, so I have some sort of "no-name" add-on wood stove and i've been researching on here what the damper looking flapper on the back of the stove was. It is attatched to a spring looking thing with a chain that hooks to the flapper. I've found out through some research this is a bimetal coil thermostat. It is indeed in bad condition and i'm going to replace it if I can find one. I know DAKA uses them as well as Blaze King so i'm assuming its worth having on my stove being that other than the flue damper I have no way of controlling air flow into the stove other than pulling the ash tray out a little. I'm going to get this thing fixed and hopefully it'll help. Anyway, anyone here know where to buy one of these bimetal coil thermostat? I just need the bimetal coil. I can attatch it to my stove damper/flapper on my own. Thanks. Leland
