kind of...that is not a model number for the furnace. It is located inside the furnace. Beyond that, if you set it only 5 degrees higher than the room temp and it fails to stay running what do you see for a flash code viewable through the window in the blower door of the furnace? Fast flash, slow flash, or flash code?
