If your refrigerator control panel not working, start with the user control and display board—this is the most common culprit when some buttons work and others do not or when the refrigerator display not working. Check that the board has power and press each button to isolate the fault; if the board has power but is unresponsive, replace the user control and display board. If the problem affects only the dispenser functions, test individual dispenser parts before assuming the dispenser control board has failed. A separate display board can also fail and show the same symptoms, so confirm which module is unresponsive. Inspect the wire harness next; loose or damaged connectors between the panel and control board are an easy fix. On some models the controls are built into the dispenser front panel, so the entire assembly may need replacement if multiple buttons are dead. Finally, rule out incoming power issues by checking the power cord, outlet, and circuit breaker.

02 - Arctic Air Refrigerator Dispenser Control Board
The dispenser control board governs most of the functions of the dispenser system. If only one dispenser part is not working, it is probable that an individual part has failed. In this case, test each of the dispenser components before testing the control board. If the entire dispenser system is not working, the control board is more likely to be at fault.
To determine if the display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the display board might need to be replaced. Additionally, if the display board is not working, check for power to the display board. If the display board has power, but it isn’t working, replace it.
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.

05 - Arctic Air Refrigerator Dispenser Front Panel
On some refrigerator models the user controls are part of the ice and water dispensers front panel. If none of the control panel buttons are working, it's probable the main control board is malfunctioning. However, if some of the buttons on the control panel are still functioning, it's more likely the unit's user control and display is faulty. If this component is sold as part of the dispenser front panel, the entire assembly can be replaced.
Ensure power cord is fully inserted into a regular electrical outlet and the outlet is supplying power. Check fuses or circuit breaker if needed. It is best to keep the refrigerator on it's own dedicated circuit and not to use a ground fault receptacle which can interrupt power to large appliances.
