How to Check the Main Board in a GE Profile Artica

Monitor the temperature of a liquid in the refrigerator and an item in the freezer. Place a thermometer inside the liquid while it is still in the refrigerator and between two items that are in the freezer. Leave the thermometer in place for a few minutes and then read the temperature. Once you have the temperature, try changing the setting on the inside of the refrigerator and freezer to a cooler setting. Wait about 10 minutes and see if the number inside of the refrigerator changes back to the original number, meaning that the temperature inside did not get any lower. If the temperature inside of the refrigerator does lower, the main board should be in good working condition. If the temperature does not lower, check the main board.

Scoot the GE refrigerator forward, unplug the power cord from the wall, and use a Phillips screwdriver to remove the lower back panel. Removing the panel will expose the main board.

Locate the J1 connector pins that are connected to multicolored wires. The wires are on the main board and are different colors depending on where they are located on the board and the purpose that they provide. Note the order of the wires and what wire they are connected to. Note the wires by color for the J1-1 through J1-5 pins.

Disconnect all the wires.

Attach the needle of the meter lead on the solid blue wire removed from J1-5. Keep this needle attached.

Attach the other needle from the meter lead onto the wire removed from J1-1 and note the resistance reading. Continue to gather readings for J1-2 and J1-3 while continuing to keep the other meter lead needle on J1-5.

Review the "Thermistor and Sensor Values" chart in your GE user’s manual to compare the resistance in kiloohms. For example, if the temperature reading you have is 41 degrees, the resistance should read 12.7 kiloohms. If the reading does not line up within a 5 percent range, the main board needs to be replaced.
