The actuator (ACT) is intended to be linked to phase (AC-H) and neutral (AC-N) conductors. It comprises a motor (MOT) provided with windings (W 1, W 1 ), a capacitor (CM) disposed between two ends of the windings and the terminals of which form a first (P 1 ) and a second (P 2 ) phase terminal. It includes a switch (TR) controlled by an electronic unit (CPU) to link the common end of the windings to the neutral conductor, at least one pair of diodes (D 1, D 2; D 3, D 4 ), the diodes of one and the same pair being connected by an electrode of the same type to a resistive circuit (RA, RB, RC, DZ 1, DZ 2 ) connected to the neutral conductor, the other electrode of each diode being respectively linked to the first and second phase terminals and means (CS 1, CS 2 ) of detecting the state of conduction of the diodes.
