My Lenox G8 series unit - 1991 - blower made today some harsh, rattling noises and some burned smoke went out. After that, it stoped dead. I was able to restart the furnace a couple of hours later, and now it runs OK. I feel it's not gona be for long untill it runs cold again.
Any clues, tips? Makes sense to replace the blower only or should I get a brand new furnace? This is only 16 years old.
What furnace brands should I look at if replacing, this is for a 2000 sq feet ranch.
