Risk level

Usually safe to check without specialist tools.
Urgency

Quick answer
A solid red light on your Echo means the microphone is off and Alexa is not listening. Press the microphone button again to turn it on; while it is red you can still control the Echo from the Alexa app.
Safety first
Stop and check this first
- With the red light on, Alexa does not respond to voice, including routines or alerts you trigger by speaking: turn it back on if you rely on voice commands.
Safe checks you can perform
- Press the microphone button again
- Restart the Echo
- Reset as the last step

Restart the Echo
- Who:
- you.
- How:
- unplug the power adapter from the Echo or the outlet, wait 10 seconds and plug it back in.
- Result that matters:
- whether after startup the microphone button turns the red light on and off again.
- If it works:

- consider a reset following your model's guide.
- Evidence to keep:

Reset as the last step
- Who:
- you, only if you accept setting it up again.
- How:
- follow Amazon's guide for your model; on the Echo Dot 2nd to 5th generation there is a reset that keeps smart home connections (Action button for 20 seconds) and a factory reset.
- Result that matters:
- whether the Echo responds to the microphone button again after setup.
- If it responds:
- the lock-up was in software.
- If it does not:
- contact Amazon support.
- Evidence to keep:
- the type of reset used and the date.
Amazon warns that a factory reset erases your personal information and any device and smart home connections.

What it means
Amazon says a solid red light shows when the microphone on/off button is pressed: the microphone is disconnected and Alexa is not listening. On Echo devices with a camera, a red light bar also means your video will not be shared. It is a privacy feature, not a fault. If the light does not change when you press the button, something else is wrong, and the light alone does not prove the Echo is faulty.
