Steps

Goal: Confirm the symptom, check for a stuck button or wiring short, then isolate the cause.

  • Listen to the chime. If it rings or chimes continuously without anyone pressing the button, the circuit is stuck closed.
  • Good: The doorbell rings constantly—proceed to Check the button.
  • Bad: The doorbell only rings when pressed—that is normal; this guide does not apply.

Check the button

Goal: Rule out or fix a stuck button—the most common cause.

  • Turn off power at the circuit breaker for the doorbell. Confirm the chime stops.
  • Go to the doorbell button outside. Press and release it several times. Look for a button that stays depressed or feels sticky.
  • If the button is stuck, remove it (usually two screws). Clean the contacts with a dry cloth. Check for debris or a worn spring. Reinstall and restore power.
  • If cleaning does not fix it, replace the button. Take the old one to a hardware store to match. Disconnect the wires, connect the new button, restore power, and test.
  • Good: The button springs back and the chime stops when power is restored—done.
  • Bad: The button is not stuck but the chime still rings—proceed to Isolate the fault.

Isolate the fault

Goal: Find whether the short is at the button, in the wiring, or in the chime.

  • Turn off power. Open the chime cover. Locate the two wires from the button (often labeled “Front” or “Trans”). Disconnect them from the chime terminals.
  • Restore power. If the chime stops ringing, the fault is at the button or in the wiring between the button and chime. If the chime still rings, the short is in the chime or the wiring from the transformer—call an electrician.
  • If the chime stopped: inspect the wires at the button and along the run for exposed copper touching. Wrap with electrical tape or replace damaged section. Reconnect at the chime and test.
  • Good: The chime rings only when you press the button—done.
  • Bad: The chime still rings with the button disconnected—call an electrician.

When to get help

Call an electrician if:

  • The chime still rings when the button wires are disconnected at the chime (the short is in the chime or transformer wiring).
  • You are not comfortable working with wiring.
  • You have a smart or video doorbell with complex wiring.

Verification

  • The doorbell rings only when you press the button.
  • The chime stops when you release the button.
  • No continuous ringing or chiming when no one is at the door.
  • The button springs back after each press.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the doorbell rings continuously without anyone pressing the button.
  2. Check the button Look for a stuck or pressed-in button; clean or replace it.
  3. Isolate the fault Disconnect the button wires at the chime; if the chime stops, the fault is at the button or wiring.
  4. Fix wiring short Inspect for exposed wires touching; wrap or replace damaged wiring.
  5. Call a pro Chime still rings with button disconnected, or complex smart/video doorbell—call an electrician.

Does the doorbell ring continuously without anyone pressing the button?

Listen to the chime. If it rings or chimes without a finger on the button, the circuit is stuck closed.

Is the button stuck or pressed in?

The button completes the circuit when pressed. A stuck button keeps the circuit closed.

Go to the doorbell button. Press and release it. Look for a button that stays depressed or feels sticky. Yes: Button is stuck—proceed to clean or replace. No: Button springs back—proceed to isolate the fault.

Yes No

Does cleaning the button fix it?

Remove the button, clean the contacts, and reinstall. A worn spring may require replacement.

Turn off power at the breaker. Remove the button and clean the contacts with a dry cloth. Reinstall and restore power. Yes: Chime stops—done. No: Button still stuck—replace the button.

Yes No

Does the chime stop when you disconnect the button wires at the chime?

Disconnect the two wires from the button at the chime terminals. Restore power. If the chime stops, the fault is at the button or wiring.

Turn off power. Open the chime cover. Disconnect the button wires (often labeled "Front" or "Trans") from the chime. Restore power. Yes: Chime stops—fault is at button or wiring; check for exposed wires touching. No: Chime still rings—short is in chime or transformer wiring; call an electrician.

Yes No

You can change your answer later.

Check wiring for exposed copper touching

Inspect the wires at the button and along the run. Look for exposed copper touching. Wrap with electrical tape or replace damaged section. Reconnect at the chime and test. Good: Chime rings only when pressed—done. Bad: Still rings constantly—call an electrician.

Done

Frequently asked questions

Why does my doorbell ring constantly?
Most often the button is stuck or pressed in—dirt, moisture, or a worn spring can keep the contacts closed. Less often, exposed wires touching (a short) or a fault in the chime unit causes the circuit to stay closed. The doorbell circuit is simple: when closed, the chime rings.
Can I fix a doorbell that rings constantly myself?
Yes. Most fixes are cleaning or replacing the button. Turn off power at the breaker before touching wires. If the button is not stuck and the chime still rings when you disconnect the button wires, the fault is in the wiring or chime—call an electrician.
When should I call an electrician for a doorbell that rings constantly?
Call an electrician if the chime still rings after you disconnect the button wires at the chime (the short is in the wiring or chime unit), if you are not comfortable working with low-voltage wiring, or if you have a smart or video doorbell with complex wiring.
