A tiny fridge may not be working correctly owing to a problem with the sealed system, a broken compressor, a failed evaporator fan motor, a failed condenser fan motor, or a thermostat. Other problems might include evaporator coils, start relays, the control board, or a drier filter limitation. A malfunctioning power source can also cause a miniature refrigerator to stop working.
Conduct a complete service on your mini fridge once a year. Have the compressor checked by an expert if it sounds like it is running too slowly or not at all. Make sure the vent holes in the back are not blocked by debris such as food particles that could cause odor issues or house fires. Check the wiring for corrosion and make sure there are no shorts between wires. Worn out or dirty contact points on the circuit breaker may not allow electricity to reach the compartments of the fridge, preventing it from cooling.
If you have had your mini fridge for more than five years, then it is time to replace the unit. The parts needed to repair these appliances tend to be expensive, and they fail most often when you need them most. It is best to have a new model installed instead; they are available in a wide variety of styles and sizes. In addition, many major appliance manufacturers make mini versions of their larger models for this market. These units usually consume less energy and are cheaper to operate than full-size counterparts.
Examine all other components to ensure that this is the source of the problem. If the refrigerator isn't cold enough, the compressor might be broken. The compressor is a motor that compresses and circulates refrigerant through the evaporator and condenser coils. There are two parts to a compressor: the motor and the drive unit. The motor turns one or more cylinders which compress gas refrigerant into a liquid. The drive unit converts electrical power into mechanical power which runs the compressor. In addition, the control board is responsible for sensing temperature changes at different locations within the refrigerator and activating various components such as the compressor motor when needed.
The first thing to do is make sure the compressor is off. You should be able to feel any heat coming from the compartment where the compressor is located if it's on. Also, look for any sign of malfunction such as bad smells or hearing noises coming from that area. If the compressor is off and there's no heat coming from it, then there's a good chance that it has failed. You'll need to have it repaired by a professional appliance technician who can replace it with a new component.
If the compressor is still on but there's no heat coming from it, that means there's probably just a leak in the system.
A refrigerator with few contents in it may also fail to perform properly. Make sure your refrigerator has enough food in it at all times, but not so much that the air movement is restricted. 6. Clogged vents between the freezer and the refrigerator compartment or between the refrigerator and the stove can prevent cold air from flowing to lower shelves.
If you find that your refrigerator fails to freeze items quickly, there could be a problem with its ice maker. This appliance makes an important part of any fridge/freezer unit, since it provides fresh ice for drinking and cooking every time you need it. However, if it doesn't work properly, this ice would be made out of water that has been through the rest of the machine multiple times (i.e., in the compressor, heat-exchanger tube network, and freezer) before being released into place where it can create ice. This could lead to corrosion and other problems with internal parts over time.
Clogged ducts can also cause refrigerators to run poorly. If you don't use the entire space inside your refrigerator, such as by leaving the door open when you put away only part of your grocery list, then food will build up on the interior walls of the fridge, blocking the airflow. This will cause your refrigerator to consume more energy heating or cooling empty rooms, while not being able to move the same amount of air through filled ones.
