Johnny W for Model Number ZISS480DMAS I just bought this board because (1) freezer light do not work and (2) water dispenser does not light up or work. I replaced the board and same problem. But I do get 28 volts leaving the board to the freezer door wires. I'm at a loss. Why would all freezer interior lights not work. Could it be burned and does not close the circuit? Could it be separate problem?
Answer Johnny, If the dispenser control is not working then you will want to test at the main control board J4 connector from the brown to orange for 12vdc. If there is 12 vdc then check at the dispenser control board same wire colors to make sure that it is receiving 12vdc. If it is then the issue will be a dispenser control issue. For the freezer interior lights not working then this will most likely be a issue of a faulty transformer. Unfortunately this transformer WR62X10030 has been discontinued by the manufacturer with no suitable replacement. Read More... Answered by AppliancePartsPros.com | Thursday, March 3, 2016
