Respuesta a "Time Capsule is overheating w/yellow flashing light"My AirPort started doing the same thing, and a few days later, completely stopped working. I just replaced the PSU and updated firmware, but the flashing yellow light with warning came up for a moment. I've cleaned the fan and it is working perfectly. I suspect there is a firmware/software issue that Apple hasn't identified yet. Update (12/21/2016): I replaced the PSU and cleaned i did a factory reset and re-updated, but all to no avail. It now works OK for a time, then signals overheating, then the fan revs up to full speed which then cools it down. This cycle repeats. I also separated and enlarged the vents for in-coming and out-going air, so perhaps it's just a buggy example.
