Troubleshooting and Cleaning Process Refrigerator Condenser Coil

Unquestionably, Refrigerators are the most useful household appliance in your home. However, sometimes they fail to run properly due to lack of proper maintenance. Among them refrigerator faces trouble mainly with cooling system. Dust can mix to the air moisture and create blocks in the coil. Here, I describe some probable reasons and solutions of cooling system. You can save a lot of money by not to go an electrician.

Due to lack of proper cleaning a refrigerator condenser may cause a lot of problems:

  1. The cooling efficiency may drop up to 30%, that's mean your refrigerator will work at only 70% efficiency.
  2. You will have to compensate thousands of money, just because the energy consumption will goes up incredibly.

Cleaning steps of condenser coil


Steps of Cleaning refrigerator Condenser Coil

Time required: Maximum 30 minutes.

Need to do this task: Every 6 month interval

Required Tools:

  1. Vacuum cleaner
  2. Paper towel
  3. Mask
  4. Coil brush


  1. Switch off all the connections: Pull your refrigerator frontward from the wall by gently pushing toward you. Some refrigerators equipped with wheels, therefore, it may convenient for you to drag easily. You have to complete all the procedure within 30 minutes, because your fridge may carry fresh vegetables and fruits. Switch off all the electric connections from circuit breaker. The first and foremost task is to disconnect all the electric connections from your refrigerator. If your fridge is equipped with water supply for making ice, disconnect it also from the water line.
  2. Identify the condenser coil: Every refrigerator has a condenser coil somewhere on the backside side of the body. Generally, the condenser coil you will find on the reverse side of your refrigerator. There you see two types of coil, one is called evaporator and another is called a condenser coil. The evaporator coil is filled with gas and absorbed heat from space. In most of the fridges it cannot be seen from outside because of safety reasons. The condenser coil is filled with water. In the old refrigerator you may find the condenser coil on the back side, generally looks like a spider grill. Some refrigerators have toe grill, you can simply pull the grill frontward or read manual guide. However, in new fridges the condenser coil is located at the bottom of the fridge. The heat from the space is further compressed by a compressor and convey it to the condenser coil and released some heat in the liquid to the air. The cooled liquid is then expanded with an expansion valve, and convey it to the compressor. This is the reason, why your fridge remains cool under Zero degree Celsius and that process repeatedly continue its work. Since the condenser coil is uncovered to the air it needs regular cleaning.

  3. Use Vacuum to clean the coil: Carefully vacuum the dirt and dust wherever you can see them. Do not let the dirt to enter inside the coil, that may result expensive repairing cost.

  4. Clean the fan: Since the fan is visible and reachable to hand, you can easily clean the fan with a vacuum cleaner. Dirt and dust decrease the fan speed that may result failure of the compressor.

  5. Use paper towel to remove stubborn dirt: You may need a paper towel to rub rigid spots. A solution of white vinegar with two cups of warm water can be safe to clean the coils. Be careful, do not rub the coil so harshly so that it becomes bent.

  6. Reconnect all the connections: Plug in all the socket connections of the refrigerator. Carefully place the water line, so that it do not leak out water.


  • If your refrigerator is placed in a storage room, you may frequently need to clean it because the compressor ventilation may block by dust.
  • Make a considerable vacant space around your fridge for passing air.
  • Stop the water line before cleaning your fridge, otherwise it may become tangled or can cause flooding in your room.


  • Be sure you have enough space to sweep away all the dirt.
  • Use mask if you have an allergy to dust.
  • Plug off all the electric connections. Do not proceed until you understand all the procedure or call an qualified technician.
