Fridge Isn't Cold
A refrigerator that isn't cold enough or isn't cooling at all can signify several problems. Check that your refrigerator hasn't been accidentally unplugged as this will prevent it from cooling completely. If the circuit breaker in your home has been accidentally tripped and no power is getting to the refrigerator even if it is plugged in, your Whirlpool still won't get any power.
Faulty evaporator coils can get so frosty that airflow cannot circulate, or the defrost timer or heater might be malfunctioning. The condenser might also be coated in dust, lint, or pet hair, so take a look at the manual to see where the condenser is located, and clean it properly. A rag might clean most of the sediment, or you can use your vacuum cleaner.
Most Whirlpool refrigerators freezers contain drains which whisk the excess moisture from the coils into an evaporation tray. The compressor, which becomes warm, heats the moisture so that it doesn't freeze and prevents the refrigerator from leaking into the bottom compartments, such as the "crisper" drawer or onto the floor. Look for the drain closely for any blockages that may have built up over time. The back wall, side walls, or "floor" of your Whirlpool refrigerator will likely contain the port into which the water is drained and will be the source of any residue buildup that prevents your refrigerator from using the proper outlets to drain and evaporate overflow liquids. These can generally be cleaned using laundry rags.
A refrigerator that is too cold may freeze the food in the refrigeration compartment, leaving vegetables and beverages unfit for consumption. As with the above issues, the self-defrost mechanism on a refrigerator, which prevents it from becoming too cool, can become blocked by any number of environmental factors, resulting in icy foods outside of the freezer compartment. Your Whirlpool will usually have a tray below the bottom shelf of the refrigeration section that catches runoff water and allows it to evaporate into the air naturally. Obstructed channels force the water back into the refrigeration system where it will eventually run off and settle in the bottom of your Whirlpool. This can cause items in the lower drawer to freeze. Try turning the thermostat up in other instances; if this does not help, the thermostat is probably broken and will need to be fixed by a qualified refrigerator mechanic.
