LEARNING HOW TO DO SIMPLE REFRIGERATION REPAIRS
Breakdown of home appliances is almost inevitable. However, refrigeration repairs are not that hard to do. Your observation skills are crucial for you to carry out any refrigeration repairs successfully. You should be particularly keen on noises and leaks.
Basics of a refrigeration unit
The first aspect you need to know is that there are two basic components in any fridge. The evaporator coil and the condenser coil. A motor and compressor circulates a liquid coolant through these coils. After the refrigerant is cooled by the condenser, it moves to the evaporator. Air in the evaporator is then cooled by the coil.
Common refrigeration repairs are easy to execute
There are several easy refrigeration repairs that you can do yourself. The common parts to have a look at before rushing to open up the fridge are the controls, the condenser coils, the power, and other parts on the outside.
Controls
Sometimes, control knobs are set accidentally. In such a case, check whether they are set correctly.
Cleaning condenser coils
Condenser coils can be cleaned at least annually. Certain types of refrigerators need bi-annual cleaning of the condenser coils, such as built-in models and side by side models. You can clean the condenser coils using the long, narrow nozzle of the vacuum cleaner.
Over time, dust can accumulate at the coils, making them less effective. Ensure the refrigerator is unplugged from the power source. First, remove the cover panel to reveal the coils. Most models allow you to remove the kick plate rather quickly. But make sure not to dent the cooling fins.
Curbing vibrating noises
Loose parts can cause noises, especially loose condenser coils or uneven supports. Using a screwdriver, tighten any parts that appear loose. Check the supports and balance them evenly on the floor.
The other culprit to refrigerator noises is a faulty evaporator fan motor. If the noise elevates when the freezer is open, the fan might be the problem. Unscrew the back cover panel and replace the motor. The motor is located just below the fan. However, if the noise is coming from the compressor fan, you probably need a new fridge.
Leaking fridge
Every fridge produces water due to condensation and melting ice. If there is a failure with that system, water can leak. If your refrigeration unit has an ice maker, you should check the back of the fridge for a leak. The copper or plastic tube could be leaking, and you might want to replace it. If the leak is in the inlet valve, all you have to do is tighten the compression nuts.
If the fridge is tilted, all you need to do is straighten it to prevent water spilling out of the pan at the back.
Ensure you defrost the fridge once or twice a week to prevent clogging the drain tube in the freezer. A clogged drain tube can also cause your fridge to leak.
