Apple error 4MOT/4/40000003 Main-3827
After upgrading to SDD the fan runs at a constant 3800 rpm. I installed OWC Digital Thermal and when that didn't work I installed Mac Fan Control. The readings for hardware on MFC are normal with nothing peeking over 100°F/37°C.
No matter what profile I apply in MFC the fans still spin at 3800rmp. Ran Apple Hardware Test which returned the following error:
4MOT/4/40000003 Main-3827

Maybe it's the battery?

Dan, I noticed the "Main 3827" in the error code is the fan speed. "Main" is the only option in Fan tab of Preference window.

Maybe it's the internal battery?

No its not the batt sensor, unless you've got a new type of laptop ;-}
mmm... I was hoping one of the sensors were damaged. Well we need to go back to the fan as the RPM feedback is the issue as I stated the AHT error was the fan unit. But as you've replaced it with a new unit we need to focus on the logic board circuitry. Somehow it got damaged.
Sadly, you'll need to find someone with deeper skills & tools here to diagnose the logic board or you'll need to replace it.

Hey Jose, I know this was a long time ago, but I've run into the same problem. Did you ever manage to solve the issue? Thanks!
