Repair crack on Refrigerator Floor

[Karan Jhavar]

Hi,

My property is in CA and my tenant dropped a something heavy on the refrigerator floor which seems to have a 1 cent big crack on it (picture below). The refrigerator was brand new.

Questions - 

If the refrigerator is working fine, are the tenants liable to fix the crack?

How much would it be to fix a crack of this size?

Appreciate your response.
