4th LED code

Unit is not mobile. 4th LED is flashing. I understand this code is stating that lift is continually stuck "on". However switches and contactors are operating correctly? Any ideas?

Fact of the week
The first practical visible-spectrum LEDs were red, not white. The red colour was the easiest to produce using the semiconductor materials available at the time (the 1960s). The alloy gallium arsenide phosphide (GaAsP) used emitted red light.
