[RE-wrenches] Cracked Glass...Warranty?

I would guess that it was the glass and tempering not complete, or done correctly.  I worked at a glass temperaturing facility most of the sheets can out fine, but every now and then a few would shatter while on the belt.  The temperaturing put to much stress in teh glass.

In my business I see quite a few broken modules each year. As I recall, in every instance there is a visible point where the impact occurred. Typically a small radial pattern is around the impact point but then random patterns over the rest on the module. Look close. Hope this helps.

Wrenches,
I recently inspected a system I installed in 2010, because the owner commented that it appeared the frost wasn't melting off of one particular module as it was from the others.  Turns out the module glass is shattered.  There are no obvious (that i can see) impact points, leading to the question... Why did the glass shatter?

I don't want to just assume, but if there is no sign of impact, I'm wondering if this could be a warranty issue?  Frame expansion/contraction due to temperature swing maybe?

Any experiences, thoughts or advice?

Module is a Sanyo HIT N215A01

Thanks,
