Safety
Turn off the breaker that powers the doorbell circuit before you touch the doorbell wiring or the transformer. If you are not sure how to do this, or if the transformer needs to be replaced, use a licensed electrician.
What to try
This article is for the Skybell Slimline video doorbell (Alarm.com models ADC-VDB105, ADC-VDB106, ADC-VDB105x, and ADC-VDB106x).
If the light on the doorbell is off, there may be a power issue, or the LED may have been turned off in Video Settings.
1. Check whether the LED was turned off in settings
If the doorbell still works in the Fluent app (for example, you can view live video or you still get notifications), the LED may just be turned off.
On the customer website, go to Video, then Settings, select the doorbell, open General, turn on the Status LED toggle, and save.
2. If the light is pulsing blue, wait
A pulsing blue LED means the battery is charging. This can last about 30 minutes after installation. Wait for charging to finish before you continue.
3. Press the doorbell button and listen for the indoor chime
If the indoor chime does not ring, the doorbell circuit may not have power. The indoor chime can also be turned off in the app, so this is only one clue.
4. Check that the circuit still has power
The doorbell transformer is often next to the breaker box, or in the walls of the house. Check that the breaker feeding that circuit has not tripped.
5. Check that the doorbell is seated and the wires have good contact
Turn the breaker off first. Make sure the doorbell is firmly on its mounting bracket and that the wires are secure under the terminal screws. If the LED only comes on when you press on the doorbell housing, the wires may not be making good contact. Turn the breaker back on and see if the LED comes on.
6. Confirm the transformer rating
This doorbell needs 16–24 VAC, 10 VA when it is wired to an in-home chime (use 20 VA if two doorbell cameras share the circuit). If there is no chime, a 10 ohm, 10 watt resistor is also required.
Transformers can weaken over time. If the transformer needs to be replaced, have a licensed electrician do the work.
If the LED shows a rapid blue double-blink, that also means a power supply issue, and the transformer may need to be replaced.
