TC A1409 Gen4 "Baking Method"

Hello, I have a Time Capsule A1409 Gen4 3T. I bought it refurbished from Apple in 2013 and it's worked perfectly until a few weeks ago. It basically has been ON for 13 years! I saw some threads describing my problem exactly (sounds like HDD or fan are on but no light) and it mentions a "baking method" but I can't seem to find the instructions for this method anywhere (all the links are unresponsive).

Does anyone know what has to be "baked" and how?

Thanks very much!

I know the problem is not the disk because when I get it to switch on, the disk is fine.
It's something else that requires either freezing the TC for a quick solution but it doesn't last or "baking" the PCB for a long lasting solution (Time Capsule light is not on - Apple Community).
This is the info I need.


Are you attempting to use macOS 26 “Tahoe” with this Time Capsule? If so, macOS 26 version does not support AFP access; Apple Filing Protocol. This removal of AFP underlies the end of Time Machine support on Time Capsule, but AFP isn’t an option on macOS 26.


In addition to AFP, Time Capsule also supports only SMBv1, which approximately nothing else does due in no small part of its insecurity and its use by ransomware botnets to encrypt the associated storage.


As for repairing Time Capsule hardware including what might be an attempt to perform a solder reflow or (given the attempts to freeze) an attempt to remove moisture, but discussing these sorts of hardware repairs is outside of what Apple prefers be discussed here.


And I wouldn’t expect much in the way of success with a 2011-to-2013-era TC anyway.


Apple started the end of TC some seven years ago, IIRC.


As for alternatives to TC, RPi and x86-64 running open-source NAS, and commercial NAS options all exist. Some of the options include Ubiquiti, Synology, UGREEN, TrueNAS (formerly FreeNAS), ZimaOS, and a Mac running macOS 11 or later and local storage.

Have you updated to Tahoe recently? If you have then your Time Capsule will no longer work with Time Machine.


If you are not yet on Tahoe then if there is a problem with the disc Time Machine will usually report it as a bad disc. If you're not seeing that then can you access the disc and see its contents directly with Finder. Also try to access it using Disc Utility/First Aid.

There were a couple of articles, authored by LaPastenague, that were titled:

  • Gen4 A1409 issues
  • New issue with A1355 Gen 3 TC


He went over the "baking" technique to "revive" a non-functional TC or AirPort Extreme logic board. Unfortunately any links I had no longer work.


He did have a few ASC posts on this topic as well, but any links to his personal website also no longer work.
