What happened?

The printer is displaying the message: Incorrect RPM reading of the fan. Please check its wiring and connection.

Error name: Fan failure

Error code: #10126

This error indicates that one of the fans of the printer is not working correctly. It measured the RPM of the SL1/S fans and found one of them out of the accepted range.

Starting from firmware 1.7.0, this error replaces Fan failure #10106 (SL1/SL1S).

How to fix it?

The SL1/SL1S has three fans:

  • The LED cooling fan (indicated in the picture by a purple arrow on the left).
  • The right blower fan (indicated in the picture by a green arrow in the middle).
  • The filter fan (indicated in the picture by a blue arrow on the right).

If the warning appears, please follow the maintenance steps for the fan that generated the issue: SL1/SL1S maintenance. When doing that, also check the cable connections of the fan to the mainboard.

If the right blower fan is the one that showed the warning, make sure that the blower gasket is still in place.

Run the Selftest once again. For SL1, navigate to LCD menu -> Settings -> Recalibration; for SL1S, navigate to LCD menu -> Settings -> Calibration -> Selftest. In case the fan also fails during the self-test, switch the connection of two of the fans, and see if the warning will be transferred to the new fan. If the error is transferred, the fan that had the warning originally may need to be replaced.
