There are some instances wherein the unit no longer starts up when turned ON. Several issues can be a reason for this problem but one of the most common reasons is found in the problem from compressors. The compressors may be burned out as it is situated in the electrical system of the AC unit. This can be avoided from happening by regularly having the unit inspected most especially the electrical system to avoid burning out the compressors.
In time it is inevitable that with constant use, air conditioning system is prone to the regular wear and tear of appliances. This is true to most air cooling system which is rooted by the degradation of the air conditioner compressor. Usual signs will show a sluggish running with the cooling cycle being turned on but there is little to no cool air coming out from the vents. This can mean compressor issues may it be loosed or worn out.
One of the main functions of a compressor is to maintain correct pressure throughout the cooling process at a certain degree. A dysfunctional compressor will display an abnormally high or low pressure discharge. To cancel out problems with compressors, this can be verified by the pressure gauges found in the unit. The user manual will indicate the right pressure gauges the unit should function. This should be properly assessed by a professional to correctly identify the compressor problems.

One of the reasons why compressors fail to run is there could be wire breaks preventing the compressor to operate. A hint of a silent hum is observed is a common symptom observed from failing compressors. This can be manually done by opening the compressor and checking of the wires are intact. It can be inspected by removing the cover of the compressor and assessing the thermal limiter. This is a very technical process to do and is recommended to be done by professionals.
In time, compressors will slow down and fail or may not start at all. This is a sign of defects found within the compressor motor. The fuse usually protects the entire motor and can be replaced to have it temporarily functional. The problem with the compressor can be temporarily fixed by replacing the fuse and wires that were worn out. If this solution does not solve the problem, then having the compressor replaced is the only solution left to do.
It is inevitable that through countless usage of our home appliances including the air cooling system, it will come to a point where everything just wears out. One of the things that should be done to prevent and lengthen the life of our AC units is by keeping it away from dusts and dirt. Replacing it entirely for a short period of time will mean added cost and not fully taking advantage of the cost we have paid for it. The compressor functions more on the air conditioning process than any other parts and that is why proper cleaning and maintenance should be done to lengthen its life.

The air cooling system is a complex piece of technology that is why certain precautionary measures should be observed when handling it. Its complexity in hardware is the reason why there are professional technicians that deal with problems of the unit operation. Taking the problem and fixing it on your own will endanger yourself. The risk of electrocuting yourself and possibly burning the unit will eventually happen when it is not properly fixed.
The user manual exists not for the user to use to troubleshoot complex problems that occur from the unit. There are a lot of tiny parts in the hardware that you are unfamiliar with that you may miss out in the process of fixing it yourself. Instances may occur like installing the wrong parts or installing it wrongly that may lead to breaking the unit even more. This will not only damage your unit even more but will impose more expenses to be fixed.
