I have a Duo therm furnace,model #90030-812 A that will not ignite.The blower comes on,but no heat. Does anyone know what is wrong with it or where I can get a replacement( I dont want to buy a new one for Hundreds of dollars).
Hi Tom, This model furnace has many safety issues. It should be replaced. It is NOT safe! Try an RV salvage yard if you don't want to spend the $. Try azrvinc.com for used parts. Or search RV salvage. Good luck!
I had my heater not light this past winter. When I got back into town the dealership checked it and found that the burners were plugged up. They cleaned the burner and it works fine now.
