Replace tenant's appliance with mine. Anything to pay attention?

[Ximing Feng]

Hi BP families! 

    Hope this finds you well! 

    So this is an inherent tenant from the previous owner. They almost own every appliance themselves. When I took the property, we said we are going to maintain the stove/oven and fridge for them. Today the tenant told me that their fridge is broken. I don't have any problem with replacing the fridge for them. But do I need to have any extra steps other than just replacing the fridge for them? Like any documentation or notice?   Any help is appreciated! 

Thank you very much!
