When you run diagnostics, or even just close the gas valve and then kick the thermostat to heat so that the furnace tries to come on, it should glow bright orange changing to white. Then the solenoid for the pilot will open, lighting the pilot.
Hot surface ignitors burn out - they wear through, especially if the furnace cycles on and off a lot.
Will try and find a photo.
If it's not the ignitor, call a tech.

Yes, it's a 311AAV. I've tried using google to help me find a resource for determining the code, but I haven't turned up anything other than generic stuff about the model having a self diagnostic feature. I just haven't found anything that comes up with what the sequence means.
Just curious-if it's the ignitor, is there any possible noise associated with it going bad? Just wondering if there's an explanation for the noise it was giving. It was kind of a squealing noise of sorts, not a real high pitch or very loud, but just one you recognize shouldn't be there.
