Is this transformer something like what a computer's power supply does (switching power supply)? Requires a (sufficient) load to operate. I would try a load resistor (SPDT switch would be easier) but I'd have to experiment with various values -- having an electronics junkbox helps!
Quite frankly it would probably be easier to just replace the electronic transformer with a regular doorbell or power transformer.
