Water and ice dispenser not working, no lights on control board. Freezer making ice. How do I test power board to check if it is working?
Answer Hello Dave,
You should first check the wiring connector at the door hinge for broken or naked/shorted wires. If no problem is found, go to the control board and check for 5Vdc between terminals J1-11 and J1-10. If the voltage is not there, replace the main board 241511102. If the voltage is there, go to the dispense board and check for the same voltage on the user interface board on terminals J1-4 to terminal J1-10. If the voltage is there, replace the display board 240596704.
