1.5 year old glass top range cracked now what

[Jason Beck]

Purchased a new range about 3 months before current tenants moved in.  They notified me today the the top glass cracked in multiple places when heating water last night.  I've talked to the local appliance shop that it was purchased from and they said it is more than likely caused from misuse or incorrect care there examples were dropping some thing, sudden change of temp by placing a cold pan on a hot burner, overheating the glass, ect.  I have no problem fixing things that are old and break but this has got me questioning them as the range is not very old and they are the only ones that have really used it.  My lease states they are responsible for any damages caused from there neglect.  Would any of you charge this back to your tenants?
