Your Hard Drive fan unit has failed!

Here's a good write up on how to read the error codes. While it's a bit dated it still works! How to invoke and interpret the Apple hardware tests

So if we dissect your error code: 4MO t/4/40000003: HDD-1293

  • 4MOT - Fan Motor
  • T - temperature
  • HDD - Hard Drive Disk

The rest is not important here
