Refrigerator Ice and Water Dispenser Not Working
Cause 1 – Dispenser Control Board
The dispenser control board is in charge of the functions of the dispenser system. If even one part of the dispenser is not functioning, it is likely that a component has failed. If that happens, you must test each component before the control board and if the entire system is not functioning, then it is likely that the control board is the culprit.
Cause 2 – Dispenser Switch
The dispenser switches are responsible for sending voltage to the dispenser. If one of the dispenser switches is damaged, then the dispenser will malfunction, or it won’t work at all. To see whether a dispenser switch is malfunctioning, you must test each switch for continuity using a multimeter. If a dispenser switch does not have continuity, then you must replace it.
Cause 3 – Door Switch
The door switch is responsible for shutting off the ice and water dispenser when the refrigerator door opens. If the door switch malfunctions, then the dispenser will fail to turn on. To see whether the door switch is malfunctioning, test it for continuity using a multimeter. If the door switch does not have continuity when it is operating, then you must replace it.
Cause 4 – Main Control Board
The main control board can sometimes fail to work properly. This is, however, uncommon. You should check all the dispenser components before replacing the control board. Consider replacing the main control board only if none of the dispenser components are malfunctioning.
