So the tenant in my rental was complaining that the refrigerator panel where the water and ice come out would pop off occasionally, but mentioned that it wasn't a big deal because she doesn't use the water or ice. Other than that it worked perfectly.

It was a somewhat older unit so out of good faith I replaced it with a slightly smaller pre owned fridge. Other than the size, the only issue was that a few of the shelves had small cracks, which I offered to order online and replace within the week and she verbally agreed.

(The old fridge was 35.5" wide and the replacement fridge is 33" wide. both were the same height and the replacement fridge was about 1" bigger in depth.)

The surrounding cabinets were custom made around the 35.5" fridge, so the fit was extremely tight, wouldn't be able to fit a 36" fridge.

She was ok with the size when we discussed it prior to purchasing it, and everything was good when I dropped it off and installed it. but about an hour later she sent me a message stating she was unhappy with the size and wanted me to purchase one of the same size as the old one. 

Legally speaking, do I need to replace the fridge with one of the exact size? 

If I do replace it with another one, that she wants, can I increase her rent to cover the price of the new refrigerator?

Just for reference, I live in Florida, and from going over our lease agreement there is nothing stating anything about appliances.

Thanks in advance,
