Don’t miss out on packages or visitors because your doorbell is broken. The fix is easy and can be done by a DIYer of any skill.
In most cases, a broken doorbell indicates a problem with the pin in the doorbell unit not firing. This small moving part is prone to wearing out.
Remove the doorbell cover and use a phillips head screwdriver to loose the wire that powers the front bell. Move that wire to the rear bell and you should be back in business. You can replicate the same sound by removing the stopper inside the doorbell.
If this doesn’t solve your problem, then check the wiring at the ringer as it may be faulty.
A wireless doorbell solves all of these problems, though, and you can even load it with your own ringtones. So if all else fails, a replacement should be simple.
