My video doorbell has stopped working properly
Power, signal and app problems separated out, in the order that finds the fault fastest
Answer first: video doorbell problems fall into three buckets, power, signal and app. Work out which bucket you are in before changing anything, because the fixes are completely different. No light and no response at the button is power. Live view spinning or the device showing offline is signal. Everything visible in the app but no chime indoors is configuration or the chime itself.
Doorbells are the part of a home security setup that gets the hardest life. They sit outside on a north facing wall taking rain, they run on either a slim battery or a low voltage transformer that was often installed for a mechanical bell decades ago, and they depend on the weakest corner of your WiFi coverage, right at the front door.
This guide separates the three buckets and gives you the safe checks for each. Where it moves into transformer wiring, chime units or getting reliable WiFi to a porch, that is where we come in, and our WiFi work exists precisely because so much security kit fails for connectivity reasons rather than security ones.

The Usual Culprits
Weak WiFi at the front door
Front porches sit at the edge of most home networks, behind a thick external wall, and marginal signal produces exactly the offline and freezing symptoms people report.
Undersized or failed transformer
Many wired doorbells are connected to a transformer originally fitted for a simple mechanical bell, which may not reliably supply what a camera doorbell needs.
Battery degradation
Rechargeable doorbell cells lose capacity over a few years and struggle badly in cold weather, giving intermittent operation that looks like a network fault.
Router or band changes
A new router, a changed WiFi password or a network reorganised into a single combined band can leave a doorbell unable to rejoin the network it was set up on.
Water ingress
A perished gasket or a unit fitted without a wedge on an exposed wall lets moisture in, which fogs lenses and corrodes contacts on the terminals behind.
Chime wiring or module fault
Where an existing wired chime is retained, the module or the connection into it can fail while the camera side keeps working perfectly in the app.
Try These Before You Book Anyone
Decide which bucket you are in
No light and no response is power. Offline or spinning live view is signal. Visible in the app but silent indoors is chime or configuration. Everything below gets faster once you know which.
Test signal at the door with your phone
Stand at the doorbell, connect your phone to the same WiFi band the doorbell uses and run a speed test. Weak or dropping signal there is your answer, not a faulty doorbell.
Charge or reseat a battery unit
On battery models, take the unit down using the supplied tool, charge it fully indoors and refit. Cold weather flattens marginal batteries and this alone resolves a lot of winter faults.
Check the consumer unit for a tripped circuit
Wired doorbells usually run from a small transformer. If a breaker or fuse for that circuit has tripped, the doorbell is simply unpowered and nothing in the app will fix it.
Restart the router, then the doorbell
Restart in that order and give the router a couple of minutes to settle before expecting the doorbell to reappear. Rushing this is why people conclude wrongly that a reboot did not help.
Confirm the chime settings in the app
Indoor chime behaviour, do not disturb modes and notification settings are all in the app and are easily changed by accident, particularly after an app update.
Check the lens and gasket for water
Condensation inside the lens or a perished seal is a physical fault. Note it and stop there, because moisture inside the unit will keep causing intermittent behaviour.
The Point Where It Needs an Engineer
Keeping it from coming back
Two things make doorbells reliable long term: proper WiFi coverage at the front of the property rather than hoping the router reaches, and a power supply actually suited to a camera rather than an inherited bell transformer. Get those right and the annual battery and app faff largely disappears.
