A residential doorbell failing to sound an audible tone when the push button is pressed can stem from several common electrical, hardware, or configuration faults. In a traditional wired system, the issue is frequently caused by a burnt-out doorbell transformer supplying zero voltage, loose wire terminal screws inside the indoor chime box, a stuck or corroded outdoor push button, or jammed mechanical plungers. In a smart video doorbell setup, a silent chime can result from incorrect app configuration, an unpowered plug-in speaker, or a depleted battery. You can troubleshoot doorbell circuits safely by testing voltage with a multimeter. You can verify that your corrective action is successful when securing loose wire terminal connections, replacing a faulty push button, or adjusting app settings restores a loud, clear ringing tone.
