This is the board for the UV Light
It appears from the models we have been able to see, that the wire colors at the Module PCB remain the same, that is. RD 12Vdc, BK Gnd, SB Sig.
On the other side of the connector the harness changes color going into the door, Light BL/WH, BL/BO, PU/WH.
At the Sub PCB on top of the door (on our model LRYKC2606S) the same wire colors are present on CON 2
With this dispenser design, it will be easier to check voltages at the UV PCB
With the unit in “Self Care” mode we saw the following voltages, 9.38dc on 12V to Gnd, and 2.9dc on Signal to Gnd.
