Arlo solid amber light on wired video doorbell: not enough power
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On the Arlo Essential Video Doorbell Wired, a solid amber light during setup means the doorbell is not receiving enough power. It needs a 16 to 24 V AC transformer; if yours falls short, Arlo points you to an electrician to replace it.
Safety first
Stop and check this first
- The transformer and chime are replaced with power off at the breaker and by an electrician, as Arlo advises; do not attempt it yourself.
Safe checks you can perform
- Tell solid amber apart from the other patterns
- Wait if it alternates amber and white in the cold
- Check the doorbell circuit has power
Leave these tasks to a qualified professional
- Do not attempt this professional task: Transformer measurement and replacement
- Do not attempt this professional task: Power Kit set to bypass mode
- Do not attempt this professional task: Case with Arlo support
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Transformer measurement and replacement
What they doAn electrician switches power off at the breaker, measures the doorbell transformer voltage and, if it is below 16 V AC, replaces it together with the chime.
They must show youthe voltage measured at the transformer and at the doorbell terminals.
In writingthe voltage found, the transformer and chime fitted and their rating.
Power Kit set to bypass mode
What they doWith the correct voltage and the doorbell still failing, the installer checks the Power Kit at the chime and enables the bypass mode Arlo describes.
They must show youwhere the Power Kit sits and how bypass mode was left.
In writingthe mode set and the voltage it was tested with.
Case with Arlo support
What they doIf power and the Power Kit check out and the light stays solid amber, open a case with Arlo with the electrician's readings.
They must show youthe case number and the firmware version shown in the app.
In writingthe case number, Arlo's diagnosis and the warranty decision.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Tell solid amber apart from the other patterns
- Who:
- you, watching the doorbell front LED during setup.
- How:
- check whether the light is solid amber, flashing amber or alternating amber and white; Arlo gives each one a different meaning on this model.
- Result that matters:
- knowing whether the issue is power, wifi or just temperature.
- If it is solid amber:
- the alert is about lack of power and the transformer should be checked.
- If it is flashing amber or alternating with white:
- follow the wifi or temperature steps in the same article.
- Evidence to keep:
- a short video of the LED during setup.

Wait if it alternates amber and white in the cold
- Who:
- you, without removing anything.
- How:
- if the LED alternates amber and white, leave the doorbell connected for up to 13 minutes so it can warm up or charge its internal battery, as Arlo states, then look at the light again.
- Result that matters:
- ruling out a passing temperature alert before calling the electrician.
- If after that time the doorbell carries on with setup:
- the installation does not need touching.
- If the light settles on solid amber:
- the doorbell is short of power and the transformer needs checking.
- Evidence to keep:
- a note of the time, rough outdoor temperature and final light.

Check the doorbell circuit has power
- Who:
- you, at the consumer unit, without opening boxes or touching wires.
- How:
- make sure the breaker for the doorbell circuit is on; Arlo asks for this check when the LED stays off, and it helps rule out an outage before you call the electrician.
- Result that matters:
- reaching the electrician knowing the circuit is live.
- If the breaker was off and the doorbell starts normally once it is on:
- watch whether the solid amber goes away.
- If the circuit is on and solid amber persists:
- call an electrician to measure the transformer.
- Evidence to keep:
- a photo of the breaker and of the doorbell light afterwards.

What it means
In its article on video doorbell LED behaviors, Arlo explains that on the Essential Video Doorbell Wired a solid amber light during setup means the doorbell is not receiving enough power. It must be connected to a doorbell transformer rated 16 to 24 V AC; if yours is lower, Arlo says to consult an electrician to replace the transformer and chime with one rated 16 to 24 V AC and 10 VA. The light alone never proves a fault, and other Arlo models use different patterns.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- Transformer below 16 V ACCommon
Arlo requires a 16 to 24 V AC doorbell transformer for this model and says a lower voltage unit triggers the solid amber light.
Evidence: What do the different LED behaviors on my Arlo Video Doorbell mean?
- Power Kit not in the right modePossible
If the voltage is already 16 to 24 V AC and the doorbell misbehaves, Arlo points to enabling bypass mode on the Power Kit fitted at the chime.

- Cold or an uncharged internal batteryLess common
Arlo lists a separate pattern, alternating amber and white, for temperature or voltage that is too low, which clears after waiting up to 13 minutes.
