Hi, I have a 1999 Carrier gas furnace. The unit does not want to stay on. I checked the thermocouple and it is fine as the unit does ignite. I've also dusted the innards and cleaned the filters. I've noticed that when I do kick it on, there is sometimes a burnt smell coming through the vents. The duct coming out of the unit gets very hot. I'm thinking it may be the blower? Perhaps it's shutting down because the unit gets too hot without the air moving out of it. Curious what others think or if it could be something else? Any info/help on how to check the blower/give it some maintenance would be much appreciated. If it does need to be replaced, is it something DIY or should we hire a pro? thanks much, Susanne
