Diagnosis
A solid red status light means the doorbell has failed its internal power-on check. It's a hardware fault, often triggered by a bad battery connection or a failed update.
How to Fix It
Perform a hard reset. This clears the internal error state.
- Press and hold the doorbell button for 10 seconds until you hear the chime and the light goes out.
- Release, then immediately press and hold again for another 10 seconds. The light will pulse yellow, then turn solid blue.
- This factory resets the device. You will need to set it up again in the Google Home app as if it were new.
If That Didn't Work
The battery connection inside the casing may be loose. Remove the doorbell from its mount, open the bottom port cover, and carefully take out the battery. Wait 30 seconds, re-insert it firmly until it clicks, then try the hard reset steps again.
Heads Up
If the solid red light persists after a hard reset and battery reseat, the unit itself is likely defective and needs replacement under warranty.
