Any HVAC guys out there?

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.

Hot surface ignitors themselves do not make any noise when operating or failed.

I couldn't hear anything out of the ordinary in the video, but such is the nature of a cellphone video posted to youtube.

Are there any diagrams or placards on the inside or outside of the access doors that list the blink codes?
