Is someone at the door?

Selkirk has a door bell problem: My door bell does not work, it is wired into something I am told is a transformer.

Mac says: First check the circuit breaker or fuse to see if it is ok. If it is, check the push button itself. If it is cracked, corroded or loose, replace it. If that does not work, replace the bell or buzzer itself, lastly replace the transformer (be sure to turn off the breaker or unscrew the fuse ) If all of that fails, you have a choice, call an electrician or buy a remote bell with no wires. They are available for single and multiple use (more than one tenant) However, the batteries in the push buttons have to be replace periodically.
