Loud noise coming from studio flash unit

Hi all,

I recently did an indoor shoot and used two Genesis 400 flash units. I took a lot of photos in close succession to each other, and after some time, maybe an hour or so, I heard a very loud banging sound that came from one of the units.

It sounded as if the bulb, or something else, exploded. I immediately inspected the flash unit, but could not see any damage to the light bulb for the flash or the light for the continuous lighting. There was no smoke burns or shattered glass anywhere.

After letting the unit rest for about two minutes, I continued using it with success.

Do any of you have any idea what this loud banging noise was and if there is anything specific that I need to inspect?

Here is the link to the flash unit and also a picture of how it looks:


Thank you for any guidance,
