There might be transient voltages feeding back from the drive motor and affecting the speed controller components from brush carbon buildup inside the motor. The carbon can buildup inside the motor...
I have found that the intermittent failures of commands has been linked to diode failure and capacitor degradation in the light machine control box. There is a set of diodes that are on the PC board...
