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?
Steve and PJM are both correct. You need to called a pro NOW. There are
ways to determine what's wrong with your furnace and to obtain error codes
but you have demonstrated you cannot perform these methods. It's okay. I
cannot either so I call a pro.
It is no joke when they say your furnace can kill you when not functioning
properly. There are plenty of cases where a family pet has died just a day
or two after a malfunctioning furnace was noticed.
FIY, I've had an electric vent damper fail causing the same issue you have
in the past, but it was a pro that determined that, not me.
