Most units have a fan to circulate cold air and maintain the compartment at a uniform temperature. Without this, the cold air will settle at the bottom, and the thermostat will not get an accurate reading, leading to over-short or over-long cooling cycles.

The fan could be broken, or part of the system that controls the fan (like the motherboard or a relay) could be broken. Additionally, the fan could have failed and taken out part of the electronics.

The refrigerator is cold at the bottom and warm at the top because warm air rises. Cold air is heavier than warm air and settles toward the bottom of the appliance.

You don't require a fan as the cold air from the freezer cools the contents of the fridge as it falls to bottom of the cabinet thermodynamically.


Why is it warmer at the top of the room then the bottom?

Because warm air is lighter then cold air. So warm air will raise (to the top of the room) and cold air will stay down. When the warm air is cooling down it lowers and when cold air is heated/heating up it raise.

What is a bottom freezer refrigerator?

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.
