The mist and flood are controlled by the EAF board. Inside the door where the FMDC hangs on the inside, is the EAF. It has two large triacs in one corner. One controls the Flood and one controls the mist. In the past I had to replace the driver IC for these as they would half wave. The duplex recepticle is for a worklight or two. The single recepticle should be the flood. Check your wiring schematic.
