Constant ringing or buzzing sound

If your wired doorbell does not stop ringing or you can hear a loud buzzing sound when connected then please check the following:

For Electronic doorbells (those that play an electronic melody):

• Check that you are not using a lighted bell push. Remove the lightbulb from the bell push or change the bell push to a non-lighted version. 
• Check there is not a short circuit and the wire connections inside the doorbell unit or inside the bell push are not touching each other.
• Check the wired bell push is not sticking when pressed, if it is then take it apart and clean using a dry cloth. Sometimes using a light spray oil to lubricate the button can help with this.

For Traditional doorbells that ring a bell or Ding Dong:  

• Check there is not a short circuit and the wire connections inside the doorbell or inside the bell push are not touching each other.
• Check the wired bell push is not sticking when pressed, if it is then take it apart and clean using a dry cloth. Sometimes using a light spray oil to lubricate the button can help with this.
