I have a Mitsubishi Electric “MSZ-GL06NA”.

The vanes seem to not move at all, regardless of any position.

The vane motor makes no noise either that I can hear.

Mitsubishi Electric doesn’t provide on the phone help for end users.

And the internet is full of SEO spam.

I tried:

  1. Cutting the power for 1 minute.
  2. Setting vane to open / close and doing #1

Is there an external reset button perhaps, what else should I do for troubleshooting?

Edit 1: Solution found! Steps:

  1. Turn breaker off
  2. Remove front panel
  3. Remove Motor
  4. Twist motor to extremes then back to “closed”
  5. Remove motor wires and reseating
  6. Putt all back together
  7. Turn breaker back on. https://lemmy.ml/comment/18994396

    The first place to start is making sure the motor is getting power and working backwards upstream from there to the control board and then from the control switches back to the control board. Diagnosing a control board failure is a bit more complicated.

      I just opened it up, reseated the connector wire.

      I also disconnected the motor completely and gave it a twist from vane fully opened to closed.

      The controller board is covered in a hard to open plastic shell, I have little interest in breaking it to figure out which prongs should have been pushed, so scratch diagnosing the board…

      AHAHAHAH IT WORKED, MOTOR WIRE NEEDED RESEATING!

    Is it still blowing air and working otherwise?

    There is an on-off button under the cover usually, but that only does exactly what the remote on-off button does.

    If your feeling game, and are comfortable with live electricity, you can get to the controller board by removing a few screws and taking off the cover. You could check that the motor cable hasn’t come loose, but thats a real long shot. Could have a look for any burnt cables or components.

    Be very careful, there is mains live electricity in there, if you aren’t sure, just replace it, the indoor units are relatively cheap.

        Breakers can be faulty, so if you have a multimeter, test to be sure. Also, the live wires are right near the front, so cover them with tape and still treat it as if its live and be careful.

        On mine (similar model, likely only cosmetically different), the live terminals are 3x screw terminals, and they are right next to the screw terminal to remove the last cover, so very easy to slip onto them.

        Edit: I see you fixed it, all good :)
