Why does the refrigerator refuse to keep the temperature and what to do with that? There are no universal answers to these questions, because the reasons for the breakdown may be different. And only a refrigerator repair assistant will be able to understand a situation, make an accurate "diagnosis" to your Whirlpool refrigerator and repair it. Among the most common reasons are mechanical damages of the seal and an imbalanced door. As a result, warm air enters the refrigeration space from the outside, preventing it from maintaining the optimal temperature. However, there are also more global issues. For example, a breakdown of the thermostat associated with wear of the control mechanism, damage to the drain line, or other malfunctions. The electronic control board is the "brains" of the refrigerator that controls major components such as the compressor and fans. Before you replace the main control board in your refrigerator unplug the power cord. Use a quarter-inch socket or nut driver to unthread the screws securing the control board access cover. Peel back any tape if applicable then carefully depress the retaining tab to detach the inner cover. Depress the retaining tab to release the old control board. Note the orientation of the wires connected to the board then disconnect them. Install the new main control board by first connecting the wires to the appropriate terminals. Align the board on the tabs and snap it into place. Carefully snap the inner cover into position. Realign the outer access cover and replace the screws to secure it. With the repair completed, plug the power cord back in and your refrigerator should be ready for use. Replacing the control board requires knowledge and experience, so experts do not recommend doing it yourself.
