- Turn the physical microphone switch or button back on
- Reboot the device and watch the LED dots when speaking
- Adjust hotword sensitivity and enable device reports

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.
Contact Google support or the device manufacturer about the physical mic switch
What they doWhen sliding the physical microphone switch or pressing the rear mute button does not clear the orange light or unmute the microphone, contact Google Nest support (or reach out to the device manufacturer for other speakers that work with 'Hey Google').
They must show youthe physical switch position, the orange light shown on the unit, and the device model.
In writingthe support case reference, the diagnosis of the switch state, and the next step quoted by support.
Crash report submission and Google Nest support escalation
What they doIf the physical microphone switch is turned on but the 4 solid orange lights stay on or the speaker still does not respond to 'Hey Google' after rebooting, turn on usage and crash reports under Recognition & sharing, submit a feedback report in the Google Home app with email updates enabled, and contact Google Nest support.
They must show youthe device model, the 4 solid orange lights or orange light ring seen, and the steps already performed.
In writingthe support case number, the diagnosis, and any quoted next step from Google support.

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.
Count the orange lights and check whether they stay solid
- Who:
- you, looking at the top or front of the speaker before pressing anything.
- How:
- check whether you see 4 solid orange lights (or the orange ring on Google Home Speaker), an orange lights countdown confirming a factory reset, or 6 solid orange lights on an original Google Home.
- Result that matters:
- separating the normal microphone-muted state from a factory reset countdown or a stuck software update.
- If you see 4 solid orange lights or the orange mic ring:
- move on to flipping the physical microphone control.
- If you see 6 solid orange lights on an original Google Home:
- an update is taking longer than expected.
- Evidence to keep:
- a photo of the lit LEDs and the exact model name of your device.
Evidence: Learn about the lights on your speaker
Turn the physical microphone switch or button back on
- Who:
- you, with physical access to the Google speaker or display.
- How:
- slide the mic switch next to the power cord on Nest Audio or Google Home Speaker (2026), on the side of Nest Mini (2nd gen) and Home Mini (1st gen), on the back of Home Max and Nest displays, or press the rear mute button on Google Home.
- Result that matters:
- turning the microphone back on so the voice assistant announces whether the mic is muted and clears the orange LEDs.
- If the orange lights turn off and the assistant answers 'Hey Google':
- the physical mute switch was the only cause.
- If the microphone is on but the assistant still gives no answer:
- continue with a power reboot.
- Evidence to keep:
- the switch position and the spoken confirmation from the speaker when toggled.

Reboot the device and watch the LED dots when speaking
- Who:
- you, next to the wall outlet powering the speaker or display.
- How:
- disconnect the power cable from the power source, reconnect it to a wall outlet, and say 'Hey Google' while checking whether the top LED dots spin or blink (or 4 colored dots show at the top corner of a Nest display).
- Result that matters:
- verifying whether the device recognizes the hotword after a clean power cycle.
- If the LEDs trigger when you say 'Hey Google':
- ask a question and say 'Hey Google, repeat the question' to confirm it heard you.
- If the LEDs do not spin or blink when you speak:
- check hotword sensitivity in the Google Home app.
- Evidence to keep:
- how the top LED dots or screen dots reacted when you said the hotword.

Adjust hotword sensitivity and enable device reports
- Who:
- you, in the Google Home app on the same Wi-Fi network and Google Account.
- How:
- adjust how sensitive your voice assistant is to 'Hey Google' and, if it still fails, open Home, All devices, touch and hold your device tile, open Settings, Recognition & sharing and turn on Send device usage and crash reports to Google.
- Result that matters:
- preparing diagnostic logs so you can submit a feedback report from your profile menu if 'Hey Google' still fails.
- If raising sensitivity restores normal voice activation:
- keep the new setting.
- If it still cannot detect 'Hey Google' with the mic switch on:
- send feedback in the app and contact Google Nest support.
- Evidence to keep:
- a screenshot of Recognition & sharing and the time you submitted feedback.

What it means
On Google's official speaker lights page for Nest Audio, Nest Mini (2nd gen), Google Home Mini (1st gen), Google Home Max and Google Home, 4 solid orange lights mean the microphone is off so Google Assistant or Gemini for Home voice assistant cannot detect 'Hey Google' or respond. On the Google Home Speaker an orange light ring shows the same state, and on Nest Hub Max an orange LED next to the camera means the rear hardware switch has disabled both the camera and microphone. On the original Google Home, 6 solid orange lights instead flag a slow update. This light alone never proves a hardware fault.
Warnings and stop conditions
