How to replace indoor ringer for my doorbell?

I have lived on my house almost 40 years and yesterday the doorbell (inside the home) started making horrible noises and i went to check it out to find it terribly hot so I took it off the wall. Now I am trying to find a replacement and have tried 2 or 3 from big box hardware stores and none work. I have a Ring doorbell attached to the outside of the house and none of the replacements ring inside OR allow the Ring Doorbell to charge and keep active...HELP QUICKLY PLEASE!
