The majority of issues with the Schwintek motors are not the motors themselves. It’s the delicate circuit boards on top of the motor with the small gauge wires soldered to the board. I recently replaced a motor and tore apart the old one. The motor worked just fine both ways when bypassing the circuit board. I soldered a wire extension to the motor with a 3 way switch and can plug into a cigarette lighter plug (which I have next to my slide) and operate the motor both ways as an emergency back up. My big slides have the in the floor slides which have one heavy duty motor and are easily accessed for manual operation.
