My furnace sounds like a pinball machine randomly. Any ideas? It started making this noise last night, so we shut it off, tried it this morning and all was fine today until 15 minutes ago when I heard it start making the noise again.

Of course it is working just fine now that I have a table that will tell me what the flashing diagnostic lights mean.
It id 90 degrees out what the hell is your furnace on for? I can see the blower????????????????????
I don't know the technical terms! It's the same unit that produces heat that distributes the cold air too.
It hasn't acted up again, but I am waiting so I can see what those diagnostic lights mean.
My unedumacated guess is the blower......
either something is in it or the bearing are going bad imo
Hasn't acted up yet. Of course.
Got a better microphone? Sounds like relays.
