I’ve attached a close-up photo of a damaged circuit board part. There are 3 “blue discs” in the photo. The left disc (of the 3 in the photo) is burned or melted open. Does anybody know what the “blue disc” that is burned open on this circuit board is or does? Again, I’ve attached a photo. Thanks for your help.

This is reallyyyyyyyyyyyyyy a WAG since the photo is so poor but it looks like a capacitor to me. Other than that there's no way anyone on the planet can tell you what it does unless they recognize the circuit board. At the very least you need to tell us, what the PC board is, from what piece of equipment, what the symptom is, and a better photo. Still a very long shot but...

I would guess that it is a surge protector like an MOV.
I think you are right. It is labeled MOV03 on the circuit board. Thank you!

If there are three of them, labeled MOV01, MOV02, and MOV03, do you think all three are required to be functional? Or if MOV03 is blown, would MOV02 & MOV01 still protect the board?

Not full protection.When you have a high speed spike an wire or combination of wires can move with respect to the others.Thus you have a protector between every combination.Hot-Neutral, Hot-Ground, Neutral-Ground..

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
Thanks Bill!
