Why is my Defiant 18000019 Intercom System doorbell playing constantly?
- JJames JacobsAug 7, 2025
If your Defiant Intercom System doorbell is playing constantly, it might be due to a diode being installed on more than one push button. Remove each push button and check for a diode. If you find diodes on multiple buttons, remove all of them except for the one on the front door push button. Alternatively, a video doorbell connected to your system might be malfunctioning. In this case, you should contact the video doorbell manufacturer for troubleshooting and installation instructions.
