Mecreator2 Radial fan problem

[K_Igor]

A similar problem was stated here: viewtopic.php?f=24&t=19297&hilit=mecreator#p38210
But there was no help.
Please help me decide. The fan for cooling the plastic is not working properly. After turning on the printer, the fan for cooling the plastic starts to work. Not possible to stop the fan either through the printer menu, or through Easyprint or RepetierHost. However, I can increase the fan speed through the printer menu or these programs, And command M107 (Turning off the blower blower of the part) in the G-code Repetier-Host line is not executed, however, the M106 command forces the fan to run at its maximum speed. This behavior of the fan has appeared recently. Thank you.
