It is a typical question the owners often ask. The situation isn’t rare, still, it needs urgent help or users risk losing their appliance forever. So when you experience the same trouble - the refrigerator is not cooling enough, still working but lights flash on and off, and temperature has gone up - have a look at our short guide. If the refrigerator is not cold enough the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem. If the refrigerator is not cold enough the main control board might be defective. This is not common. Check the defrost system, cooling fans, and cooling controls first. Old boards often need replacement. Unfortunately, some of them may turn out to be not repairable. To know that for sure call a professional worker who can conduct a diagnostic and help with buying new parts.
