You may have a faulty defrost timer. This is generally a small plug in unit at the lower front under the fridge. If you have a vent grill, take if off and look, if you see a small black unit about half the size of a cell phone, with a wireloom containing 3-5 wires, that could be it. Unplug it and take to a good appliance parts store. -I've found this to be the commonest problem of not cooling properly, although there may be other issues.
The function of the freezer evaporator in a refrigerator is to absorb heat from the air inside the freezer, causing the temperature to drop and freeze the items stored inside. This process helps maintain a cold environment in the freezer compartment.
In most refrigerators, only the freezer is actively cooled by the compressor, while the refrigerator section relies on cold air being circulated from the freezer. There's usually insulation between the two compartments, and adjustable vents control how much of that cold air enters the fridge side. The temperature dial in the refrigerator doesn’t make the fridge colder directly—it just opens or restricts airflow from the freezer. If these vents get blocked, the fan fails, or the airflow is restricted by frost buildup, the fridge can warm up even if the freezer stays cold. Source : appliancerepair-sd dot com
My freezer is at the bottom. The freezer being at the top isn't universal, it was just a common design for a time.
Having the freezer at the top of the refrigerator allows cold air, which is denser and tends to sink, to flow into the refrigerator compartment more easily. This design also makes it more convenient to access frequently used items in the refrigerator.
The freezer evaporator fan in a refrigerator helps circulate cold air throughout the freezer compartment. This fan plays a crucial role in maintaining a consistent temperature by distributing the cold air produced by the evaporator coils. By continuously moving the cold air, the fan ensures that the freezer stays at the desired temperature, contributing to the overall cooling process of the refrigerator.
A refrigerator has a freezer and a cooler compartment. Very cold air from the freezer compartment is blown over the cooler compartment below to cool the product while a Cooler has no freezer compartment.
it may be out of coolant.
its not always at the bottom its just the way yours is made some other people have asked why is it at the TOP of the refrigerator so my answer is that its just a selective spot depending on what fridge you have. In fact, the majority of refrigerator/freezer combinations have the freezer on top. As mentioned in other posts, hot air rises and cold air sinks, so freezer-on-top models can transfer cold air to the refrigerator without using as much electricity as other models, making freezer-on-top models the most energy efficient refrigerators (generally speaking) that you can buy.
There could be several reasons for this issue such as a malfunctioning compressor, evaporator fan not working, or a problem with the thermostat. It's best to unplug the refrigerator, check for any visible issues, and then consult a professional repair service if needed.
It might be out of freon.
because it doesnt work anymore. you need to get it fixed
Bottom so less cold air escapes and most people use refrigerator more than freezer which will require less bending over.
