How do I word the lease for appliances I don't want to repair

[Susan M.]

As a landlord I take responsibility for keeping in working order items like the furnace and AC, refrigerator, stove, dishwasher, etc.  However, I have a property that has an extra freezer in the basement and a dehumidifier that was left by a previous tenant.  The new tenant would like to keep and use these items, but I want to be sure that my lease is clear on the fact that should these two items no longer work that I take no responsibility for them.  Basically they are "extras" and they are for the tenant to use until they no longer work, and at that time they just don't get to use them anymore, or they can replace them themselves.  How on earth do I word that in the lease?

Thanks!
