Condenser and evaporator fan replacement

In refrigeration engineering, a fan increases the heat transfer efficiency of evaporators and condensers, while providing the fastest possible cooling of foods. If a refrigerator fan fails, it needs to be replaced immediately. Let’s take a look at the problems that can occur if the condenser and evaporator fan fails. If the condenser fan fails, the following problems can occur:

  • Compressor overheating and jamming;
  • Poor cooling capacity;
  • Rising temperature in the refrigerator.

If the evaporator fan fails, problems with the refrigeration unit manifest themselves as:

  • Loss of cold in the compartment itself;
  • Compressor wedging.

Replacing the evaporator fan in a refrigerator

What is the evaporator in a refrigerator? It’s a refrigerator assembly that converts refrigerant from a liquid state to a gas. In other words, the evaporation process takes place in this unit. The compressor creates pressure and the liquid Freon flows from the condenser to the evaporator area. If the evaporator is not working, there is no cooling and the refrigerator is not able to keep cool. If this unit fails, you need to react quickly to the breakdown and replace the broken part.

To replace the evaporator fan in your refrigerator, follow these steps:

  • Turn off and defrost the refrigerator;
  • Remove the evaporator cover, unhook the ground wire and ice maker wires;
  • Remove evaporator fan cover;
  • Remove the fan motor, remove the blades, and remove the motor from the mounting bracket;
  • Install the new evaporator fanand reassemble in reverse order.

How to know if there is something wrong with the refrigerator evaporator fan

With the help of the fan, cold air from the evaporator is forced through special ducts and distributed throughout the refrigerator compartment. Some of the most common signs of a fan breakdown in refrigerators include:

  • No fan noise. The fan is most likely burned out if no fan noise is heard when the compressor is turned on, while the sound of the motor running remains.
  • The fridge compartment is not cooling. If you notice that the fridge compartment does not cool well or does not cool at all, the reason may be a faulty fan.
  • The freezer is not freezing enough. An increase in temperature in the freezer compartment may also indicate a broken fan.

Main condenser and evaporator fan failures

Condenser and evaporator fan replacement

1. Electric motor. If the fan does not work, it may be due to the failure of the electric motor. A technician can diagnose the problem. 

2. Freezing. Sometimes the fan blades freeze. This may result from an obstruction of the drainage hole for runoff water. 

3. Continuous operation. If the fan runs continuously, the evaporator may be the cause. If the evaporator is covered with ice, the air starts to circulate poorly.

When the fan malfunctions, it is important not only to repair or replace it, but also to determine the exact cause of the unit’s failure. The range of diagnostic and repair work should be left to a professional technician.
