We had a power outage not too long ago and noticed that our blower began to run continuously, even with it shut off from the thermostat. The glow igniter glows really hot but nothing else seems to happen. What could be wrong with it? I've read a lot of answers, but with the igniter working I'm not sure if it's the limit/pressure switch or not. Any ideas would be greatly appreciated. Also... the LED indicator stays on, suggesting everything is fine. =/ Obviously something isn't right.

Please provide us with the model number of the furnace.

Gmpn080-4

We ordered another circuit board just in case that may be the issue. We've had a few power outages over the summer. Any help would be greatly appreciated, this is our first time working on a gas furnace.

Another thing, I don't know if I can get help with or not, is that the igniter glows really hot and I've noticed the first two burners, are covered in soot as if they've been getting too hot and the cover also, has shown signs that the burners are too hot on that side. What could be the malfunction in that?

With the soot being present, I suggest you call a local professional. There is a strong probability there is a major internal problem with the furnace.
