A method for controlling an electric ventilator includes: setting a first threshold temperature T1D of a microcontroller lower than a maximum threshold temperature T3D of the microcontroller; monitoring a temperature TD of the microcontroller; setting a first threshold temperature T1M of an electronic power device lower than a maximum threshold temperature T3M of the electronic power device; monitoring a temperature TM of the electronic power device; preparing a counter of a predetermined time X; activating the counter if the temperature TD or the temperature TM exceeds respective first threshold temperatures T1D, T1M; reducing a speed V of rotation of an electric motor to a second value V1 lower than a first value V1 if after the predetermined time X, the temperature TD or the temperature TM is higher than the respective first threshold temperatures T1D, T1M.
