Motor or board decision
Mitsubishi Electric Starmex 3 blinks is repair-first when the motor, blade, or feedback circuit is confirmed. Replacement becomes relevant only if motor or board cost is poor value for the system age.
Obstruction or loose connectors are simpler than a failed motor or board output.
Motor replacement depends on whether feedback and winding tests confirm failure.
Board replacement should follow motor and harness checks, not replace them.
