Apple MacBook Pro F107 Error Code Fix Guide

What This Error Means

On Apple MacBook Pro, code F107 generally means a cooling fan speed/sensor fault, usually the left (Fan 1) not reporting correctly.

Translation: the fan isn’t spinning or being read properly, so the Mac overheats or runs fans at full blast and may shut down under load.

Official Fix

Apple’s playbook is simple: rule out dust and firmware, then replace the bad fan or logic board.

  • Shut the MacBook Pro down, unplug the charger, and let it cool for at least 10 minutes.
  • Check every vent and grill (hinge area, sides, bottom) for dust, pet hair, or tape blocking airflow; gently clear with a soft brush or low‑power vacuum at a distance.
  • Update macOS to the latest version your machine supports; this also pulls the latest firmware and fan control profiles.
  • Reset the SMC (Intel models only):
    • T2 models (2018–2020): Shut down, then hold Right Shift + Left Option + Left Control for 7 seconds, keep holding and add Power for another 7 seconds, release, wait 10 seconds, then power on.
    • Older Intel: Shut down, then press and hold Left Shift + Left Control + Left Option + Power for 10 seconds, release, then power on.
  • Run Apple Diagnostics again: hold the power button at startup on Apple silicon or hold the D key on Intel until the diagnostics screen appears; confirm F107 repeats.
  • If F107 still shows, Apple’s official answer is hardware service: book Apple Support or an Apple Authorized Service Provider to replace the failing fan assembly and, if needed, the logic board.

The Technician’s Trick

What a bench tech actually does before swapping a whole board.

  • If you’re under Apple warranty or AppleCare: stop here and let Apple handle it; opening the case can give them an excuse to say no.
  • Pop the bottom cover and clear the junk:
    • Remove the Pentalobe screws, lift the bottom cover carefully.
    • Hold the fan blades still with a plastic tool or cotton swab so you don’t overspin them.
    • Use short bursts of compressed air from both sides of the fan and heatsink to blow out dust; don’t let the fan free‑wheel like a turbine.
  • Check the fan by hand:
    • Spin it gently with a finger. It should turn smoothly and coast a bit.
    • If it feels gritty, catches, or barely moves, the fan is done. Plan on replacement.
  • Reseat the fan connector:
    • Locate the fan cable where it plugs into the logic board.
    • Carefully pop it straight up to disconnect, then push it straight back down until fully seated.
    • A half‑loose connector is a classic cause of F‑series fan codes after a previous repair or drop.
  • Test with fan‑monitor software:
    • Reinstall the bottom cover loosely, boot into macOS, and use a tool like Macs Fan Control or TG Pro to read fan RPM.
    • If the fan shows 0 RPM or jumps around wildly while the Mac is clearly trying to spin it, the fan itself is bad.
    • If RPM looks normal but you still get F107, you’re looking at a sensor or logic board issue.
  • Swap the fan before the board:
    • Remove the fan screws, disconnect the cable, drop in a known‑good replacement fan, and reassemble.
    • Run Apple Diagnostics again. If F107 disappears, you’re done for cheap. If it stays, the fault is on the logic board fan driver/sensor line.

Bottom line from the field: nine times out of ten, F107 is a dirty or dying fan, not a cursed logic board.

Is It Worth Fixing? (The Financial Verdict)

  • ✅ Fix: Machine is under 6–7 years old, runs fine otherwise, and a fan swap quote is under about $200 (or you can DIY for far less).
  • ⚠️ Debatable: 7–9 years old, multiple issues (battery weak, ports flaky), and shop is talking $250–$400 because they want to replace the whole top case or logic board.
  • ❌ Replace: 9+ years old, liquid damage history, or anyone quotes you more than half the cost of a solid used/refurb MacBook Pro for fan/board work.
