I realized that my doorbell didn

I realized that my doorbell didn’t seem to be working. At the time, I knew nothing about doorbells so I called the home warranty company and they had me call an electrician. He came out and did all sorts of fancy tests on my electrical system. He used a machine that tested the wires from the doorbell switch to the transformer. All the wires seemed to be good. Finally, he realized that there was no chime. It seems that the seller had removed the chimes before he left the house.
Had the chimes been broken, the electrician could have replaced or repaired them. As they were not even installed there was nothing that he could do.
