Furnace is running, but no heat is blowing into our house. It smells like a candle that has just been put out. The vent pipe that goes to the chimney is hot to the touch. What do I need to do?

What do I need to do?


Check it out and give us more info,like what is working and what's not, like is inducer fan running? Like does igniter come on? Like does the burners fire up? If so how long do they stay fired up? like does the blower come on?(the big fan that blows the heat into the home), with this info maybe we can be of some help,, also you are going to be asked the model number of your unit
