Quick answer

If your eero LED is flashing yellow or orange, eero calls it a power supply problem: the eero is not getting enough power. Reconnect it with the adapter and cable that came with it, firmly plugged in, and try a different wall outlet.

Safety first

Stop and check this first

eero recommends always using the included adapter and cable: a third-party USB-C charger may not deliver the power the eero needs.
The eero PoE Gateway does not flash: it shows a power problem with a solid yellow LED.

Safe checks you can perform

Inspect the cable and adapter
Reconnect firmly and try another outlet
If your eero runs on PoE: cable, switch and port
Rule out a recent soft reset

Open a case with eero Support
What they doIf the LED stays yellow with the original adapter and cable, firmly connected and on another outlet, eero Support reviews the case and a possible adapter replacement.
They must show youwhich cable, adapter and outlets you tried and the LED colour each time.
In writingthe case number, the diagnosis and whether the adapter or the eero is covered by warranty.
PoE installation check
What they doWhoever installed your wired network confirms that the PoE switch or injector meets the standard your eero model needs and that the cable and port are sound.
They must show youthe switch PoE specification against the one your eero model requires.
In writingwhich part was changed (switch, port, cable) and the result.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

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.

Inspect the cable and adapter
No special tools
Who:
you.
How:
look over the power cable and adapter for cuts, kinks or fraying, and confirm they are the ones that came in the eero box.
Result that matters:
ruling out a damaged cable or a third-party USB-C charger.
If the cable or adapter is damaged or not from eero:
replace it with the original.
If everything is intact and original:
check the connection and the outlet.
Evidence to keep:
photo of the adapter label and the cable used.
Evidence: Why is the LED on my eero flashing yellow?
Reconnect firmly and try another outlet
No special tools
Who:
you.
How:
connect the eero with its original adapter, push the cable firmly into both the eero and the wall outlet and, if nothing changes, try a different wall outlet.
Result that matters:
the LED turning solid white.
If it turns solid white:
the eero is connected and working normally.
If it still flashes yellow:
the power adapter may need to be replaced.
Evidence to keep:
note of the outlet tried and the final LED colour.
Evidence: What do the colors of the LED light on my eero mean? · Why is the LED on my eero flashing yellow?
If your eero runs on PoE: cable, switch and port
No special tools
Who:
you, if the eero is powered over Ethernet (PoE).
How:
check the Ethernet cable for damage or loose connections, confirm in your model's specifications that the switch or injector supports the required PoE standard, and try a different port on the switch.
Result that matters:
ruling out a PoE source that does not deliver enough power.
If it turns solid white on another port or cable:
keep that connection.
If it stays yellow:
if you have the included power adapter, test with it to rule out a fault in the eero itself.
Evidence to keep:
switch or injector model, port used and result.
Evidence: Why is the LED on my eero flashing yellow?
Rule out a recent soft reset
No special tools
Who:
you.
How:
think whether someone has just held the reset button: during a soft reset the LED flashes yellow when you release it and then flashes white while it boots.
Result that matters:
telling the reset signal apart from a power problem.
If the button was just pressed:
wait about two minutes for it to return to solid white.
If nobody touched it and it stays yellow:
continue with the power steps.
Evidence to keep:
note of the time and whether the reset button was pressed.

What it means

In eero's official LED colour table, flashing yellow or orange means power supply problem. eero explains that the device monitors the power it receives and flashes yellow when the source does not meet its requirements: a USB-C cable or adapter not approved by eero, a damaged or loose cable, or a PoE switch or injector that does not deliver enough power. The eero PoE Gateway shows solid yellow instead. The LED alone never proves the eero is faulty.
