Your mini fridge freezer may not be keeping the cold air inside. The problem could be caused by obstructions in the cooling system. You should remove the obstruction to resolve the problem. You can also check the fan motor to see if it is functioning properly. If it is not, you should consider replacing the evaporator fan unit.
Replace the evaporator fan
When your mini fridge freezer doesn’t keep your food cold, it’s important to replace the evaporator fan. The problem can be caused by a blocked or obstructed fan, or a faulty relay. It might also be caused by objects wrapped around the fan blades. If you notice this problem, remove the wrapped objects and then turn the freezer back on. If the problem persists, replace the evaporator fan with a new one.
The evaporator fan is responsible for drawing the cool air from the evaporator coils. If it has stopped running, ice will form on the evaporator coils, preventing the cool air from circulating through the freezer. To replace the fan, follow the manufacturer’s instructions and follow the steps listed below.
Check the thermostat
One of the first things to check when your mini fridge freezer is not cold is the thermostat. It should be set to the coldest setting. You should also make sure that the door gasket is in place and that the condenser coils and vents are clean. Make sure that the fans are working properly as well.
You can also check the defrost timer. These can be located on the back of the fridge or on the bottom behind the kick plate. They can be either electrical or mechanical. If the electrical one is malfunctioning, it is important to replace it.
Clean the condenser coils
Cleaning the condenser coils can be a simple way to fix a mini fridge freezer that is not cooling. Generally, they accumulate dust and debris over time. You can clean them by vacuuming them and using a stiff brush. Try to remove as much debris as you can from the coils and fan. If necessary, you can also use a flashlight to inspect the coils and fan.
Clean the condenser coils by using a vacuum tool that has a narrow attachment to reach these areas. You can also use a long-handled brush to clean out stubborn dirt. The coils will need to be cleaned from all sides so that air can flow through them.
Check the circuit breaker
If your mini fridge freezer does not have a cold temperature, the first step you should take is to check the circuit breaker. This is usually found in the electrical service panel of your house. If the breaker is tripped, reset it. Most homes have a dedicated circuit for refrigerators, and older homes may have a separate kitchen circuit. You can also check the outlet behind the refrigerator by plugging a lamp into it.
If the circuit breaker is tripped, the likely culprit is a faulty part. Refrigerator parts will often break before the breaker is tripped. It is highly unlikely that the circuit breaker is tripped due to the thermostat, since the refrigerator uses a small amount of power. However, it is possible that a fan may be causing the problem.
Replace the control board
There are a number of potential reasons for a mini fridge freezer not cooling. First, it may be due to a faulty thermostat or seal system. Next, it could be a faulty start relay or compressor. The start relay is the part of the refrigerator that makes the compressor run repeatedly to keep the cooling unit at the right temperature. When this part fails, you’ll hear a clicking sound.
If you cannot diagnose the problem, you may need to replace the control board. This part controls many of the refrigerator’s components. First, you need to unplug the fridge and examine the control board. Check for burnt connections, deteriorated foil, and electrical arcing. If you find these issues, the board is likely to be the problem. If you’re not sure what the problem is, you should call a technician.
