Exhaust-0

Last week, I noticed that my laptop’s fan didn’t seem to work and my computer was running much hotter than usual. I booted up into the Apple Hardware Test, and ran a test. It quickly gave me an error (4MOT/1/40000002: Exhaust-0) that essentially means, “Your fan is dead. And you might want to check on your logic board, too.”

Since my computer is under warranty, I brought it to an Apple store and let them deal with it. They confirmed that the fan wasn’t working and that I needed another one. They warned me that it could take up to 5 days before they were done with the repair. They weren’t sure if they would also need to replace the logic board, but they would go ahead and order both parts anyway.

It ended up being much less of a hassle than I expected it to be. All they needed to do was replace the fan so I got it back a couple days later. Everything has been working fine ever since!
