5 causes of refrigerator not cold and how to overcome them: Okezone techno

REFRIGERATOR not cold to be a problem that is often encountered. If so, it will be very annoying because it can cause food to rot which leads to losses.

For those who experience this problem often, it’s important to know the cause and how to overcome it so the problem doesn’t recur in the future. So here is the explanation, according to various sources.

1. Vent blocked

The air temperature inside the refrigerator is maintained through a series of internal and external vents. To maintain a constant temperature, these vents must remain open.

Often people unknowingly block these vents with food or don’t even clean them until dirt builds up. To overcome this it is necessary to keep the ventilation slots free.

2. Dirty condenser coil

Another cause is the presence of dirt in the condenser coil. Of note, the condenser coil releases heat from inside the refrigerator, if the coil is dirty, the refrigerator has to work harder to remove it.

An easy way to deal with it is to use a vacuum cleaner or a long brush. Vacuum the dirt clean so that the condenser coils effectively release the heat from within.

3. Condenser fan motor is faulty

Failure to cool the refrigerator can also be caused by a problem with the condenser fan motor. The condenser fan motor works by pulling air over the condenser coils to cool it.

Without a working fan, your refrigerator can easily overheat and not cool properly. If the fan motor fails, take the refrigerator to a professional for repair.

Refrigerators have one or more evaporator fan motors. If the unit is equipped with only one fan, it will be placed in the freezer compartment. The evaporator fan motor circulates cool air from the evaporator coils throughout the compartment.

If the fan motor fails, the freezer may stay cold, but there is no refrigerant in the refrigerator compartment. Repair if evaporator fan motor has a problem.

5. Control board is defective

Modern refrigerators use at least two circuit boards, namely the main control board and the temperature control board. Damage to any of these control boards can cause temperature problems.

This problem is not easy for beginners to diagnose or fix, so it is best to contact a service professional if you suspect a control board failure as fixing it incorrectly could have disastrous results.
