How to Fix a Buzzing Doorbell
If you’re experiencing a buzzing doorbell, the best way to fix the problem is by identifying the noise source. Once you know what’s causing the problem, you can take steps to correct it.
To fix a humming doorbell, you can follow these steps:
Step 01: Identify the Source:
Initially, it is to determine where the sound is coming from. This can be done by carefully inspecting the doorbell wires and buttons. If you’re not able to determine the cause, you may need to call a professional.
Step 02: Repair the Wire:
If you find that a wire is loose or broken, you can fix it by twisting it back into place. If the wire is too rusty, you may need to replace it. To do this, you can follow:
- Turn Off the Power: Before doing any work on the doorbell, turn off the power by flipping the breaker doorbell switch.
- Unscrew the Plate: Use a Phillips head screwdriver to remove the plate that covers the doorbell.
- Remove the Doorbell Plate & Button: To get to the wires, you’ll need to remove the doorbell plate & button. This can be done by unscrewing the mounting screws.
- Cut and Strip the Wire: Cut a piece of wire about a couple of inches long. Strip the insulation off of each end of the wire.
- Twist Wire Together: Twist the two ends of the wire together to form a tight connection.
- Reattach the Plate: Screw the plate back into place using a Phillips head screwdriver.
- Test the Doorbell: Press the doorbell button to test the connection.
If you’re able to repair the wire, it’s good to put some electrical tape around the connection to keep it from coming loose.
Step 03: Clean the Buttons:
If the buttons are dirty, you can clean them with a damp cloth. Be sure to dry them off completely before continuing. If you use wet clothes to clean the buttons, it will cause more problems.
Step 04: Replace the Doorbell Transformer:
If the electrical transformer is bad, you may need to replace it. The new transformer should have the same voltage and amp rating as its predecessor. If you’re not sure how to do this, you may need to call a professional.

If you fail, you may need to reset the doorbell. This can be done by pressing the doorbell button for 15 seconds. If the doorbell doesn’t work, a professional may need to be called.
Step 05: Replace the Wires:
If the low voltage wires are bad, you may need to replace them. You’ll need to cut the wires and strip off the insulation to do this. Twist the two new wires together and screw on a connector. Be sure to use the same color wire like the old one. If you’re not sure how to do it, consult a professional.

02. What Causes Doorbell Transformers to Buzz?
There is a possibility that the button is stuck in the contact position if your doorbell is excessively buzzing or humming. This will burn out the electromagnet in the transformer if it buzzes continuously for an extended period. Thus, the bell or chimes unit will not operate, even when the button is pressed.
03. How Do I Stop My Doorbell Transformer From Buzzing?
It is imperative that you immediately disconnect the low-voltage cable from the button. The bell unit (or transformer) will burn out if the transformer is not replaced. You can clean the contacts with rubbing alcohol by unscrewing the button from the exterior wall.
04. Why Is My Doorbell is Buzzing After Installing Ring?
Your doorbell chime essentially acts as if it’s receiving a very low-powered doorbell press, which occasionally sounds like humming or buzzing. The doorbell is sounded due to small vibrations within the mechanism that causes the bell to strike.
