Carrier furnace not firing
This started last winter. Didnt think much of it but now not working at all. I went and did some trouble
Shooting. This is what is happening (gas self igniting furnace) if i shut power off when i turn
It back on immediately will blow cold air, then i can see the ignitors start to glow, but nothing happens. They
Shut off after about 30 seconds. It will repeat a few times and then quit when it doesnt ignite. So it seems all is working
But for some reason its not actually igniting. It working sometimes! Every once in a while the furnace will
Kick on and warm up the house.

Sounds like your gas valve solenoid may be defective if your ignitor glows but there's no fuel to ignite and burn (e.g. flame).

Is this a DIY fix? I fix most things myself, have worked on my gas water heater
But not my furnace.

I cannot answer your question because I do not know your abilities, experience and skill level.

Question - Are you sure the NG is turned On and being fed all the way to the valve?

I would recommend a service call to get it fixed. It shouldn't be anything major or overly expensive to repair.
