The compressor is equipment that takes some kind of gas, and puts it under a lot of pressure to compress it, it means that it squeezes a lot of gas in a small space. Then, on one side, the compressor collects refrigerant, which arrives in the form of low pressure, low temperature gas. For those who do not know, without the best air compressor for home garage, appliances such as air conditioning and refrigerator could not handle the temperature. Inside, it stores this gas and compresses it. On the other side, the compressor releases this pressurized and heated gas.
How to know if it is damaged?
The compressor is one of the fundamental parts of air conditioning. And as it is located outside the environment, inside the condenser. It is more difficult for the user to identify when problems start to appear. The damaged compressor causes the evaporator to start releasing hot air instead of cold air, the air conditioner stops freezing, electric bills increase, voltage fluctuation, etc. And a lot of people think that when the air conditioner stops working, it’s for lack of gas. Well, most of the time, it really is. However, lack of gas, or even excess, can result in major compressor problems if not resolved immediately. So just replacing the gas is no use.
How to tell if the problem is in the compressor?
When a customer who has requested technical assistance, it is common to have some questions regarding the source of the air conditioning problem. Even if the first impression is that the problem is with the compressor, some procedures need to be done first.
For this it is necessary to check the capacitance. It cannot be below nominal. In addition, basic testing is required to find voltage and current. And the equipment used for these tests is a multimeter or clamp meter. If you detect that the capacitance is ok, the voltage is lower than the local standard, and the current higher than the nominal, then the problem is even with the compressor of the air conditioner. One of the problems that can easily be mistaken for compressor failure is the lack or even excess refrigerant. This adversity can even lead to more serious compressor problems if not resolved quickly. The Basic symptoms are,
• The electricity bill has increased a lot.
• The air conditioner has stopped freezing the environment.
• the air started to come out hot from the evaporator instead of cold.
• The condenser began to make more noise than usual.
Compressor with damaged coil
Coils that are internally inside a compressor are usually damaged by high voltages, usage time or high temperatures inside the compressor. This causes the electric coils to not work properly and the air conditioner cannot start or cannot start.
Compressor does not start with open coils
When the air conditioner compressor does not start because it has damaged electric coils, sometimes the compressor does not even attempt to start. The technician should know how to measure the electric coils of a compressor to know if it is in good condition.
Does not start compressor locked
The problem occurs when the compressor tries to start, but fails to do, because it is locked. In this process it consumes more amperage than normal even much greater than that starting amperage for which it was manufactured.
Main causes of blockage in compressors:
• An old compressor with a long service life can generate wear.
• The air conditioner has an excess charge of refrigerant gas
• High pressure in the condenser due to lack of maintenance, fan stopped, etc.
• When the air conditioner does not start because it is grounded, it implies that one of the three coils are overheating.
