Do doorbell transformers put out AC or DC?

6 Answers. Your door bell is being fed from a step down transformer. Somewhere in your house is a small transformer that is getting 120VAC (primary) and stepping it down (secondary) to a lower AC voltage between (typically) 16 to 24VAC.

How do you know if your doorbell transformer is bad?

A reading of 16 volts indicates the transformer works properly. Less than 16 volts indicates the transformer needs replacing. Touch each probe of a low-voltage test light to each screw head on the transformer if you are not using a multimeter. If the lamp fails to light, the transformer is bad.

Will doorbell wires shock you?
