Nitpicky Tennant that wants everything

[Freddy T.]

Im a new landlord and a newbie. I recently have a new tenant who has been there for a month and wants a new fridge, wants me to add a new light switch to the bathroom to turn off fan exhaust to save money on electricity, wants me to buy new door alarms.

The fridge is functional and working, he is upset that the insides bend a little when he puts a lot of food in there. Its a little on the old side but it works fine. 

The fan exhaust in the bathroom turns on with the light at the same time and wants me to add a new light switch specifically for the fan exhaust to save on electricity and said "I'm not going to pay extra for that."

There are no door bells on the apartment and wants new door bells.

It feels like its never-ending. He also wants to get compensated for doing extra fixes around the house like changing the flapper from the toilet for example.

How do I fix this situation? It feels like its never-ending.
