Hello, new here. Weve had a mahoning outdoor furnace for about 5 years now. Never any major issues until last night. My husband went down to put wood in at 7:30 this morning and walked into the wood burner shed to find steam and water everywhere. The stove was overheating and temp was at 210. We shut everything down, put water in and got it up and running again. I just went down to check it and it was about 5-7 degrees above the set temp but the blower fan was still running. Could that be the issue?? The fan wont shut off? And why would it do that?
