What's the failure mode? (open secondary would be my guess)?

I don't follow the sentence on 'gounding'.

Hi.
We can't keep our doorbell stepdown transformer working. I thought i would check this group for thoughts.
The transformer drops to 16v. That matches the input for our doorbell.

The transformer is connected to ground and both the black and white house wires (as directed on installation instructions).

It is installed onto a standard junction box with (which has a cfl attached).
I've changed transformers multiple times. I checked the doorbell. I found no problem, but thought a $20 change of bells might so it, so I changed it anyway (after the 2nd transformer).
Any thoughts?
