In the words of many repairmen an ac compressor is the heart of an ac system.
Auto air conditioning compressor cycles on and off. Regardless if idling or driving the a c compressor clutch cycles on and off constantly. Since the mid 1990s most cars equipped with air conditioning have also been outfitted with electronic modules that tell your car s ac compressor to cycle on and off. If your air conditioning unit turns on and then off immediately then you most likely have problems with the electrical components or the run capacitor. Air conditioner short cycling simplified.
Without the cycling switch to activate the compressor s clutch the ac system will not be pressurized correctly and the system will be unable to produce any cold air as a result. Pressure on low side ranges from 35 45 psi. I turned the a c off and stopped putting r 134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Air conditioner turns on and off right away.
Air conditioner short cycling occurs when something within the system prevents your unit from completing a full cooling cycle. Is your air conditioning system turning on and off right away after only a few seconds or minutes of running. If you begin to notice that the ac system is no longer functioning as it used to and you suspect that the clutch cycling switch may have a problem consider having. Although it may be alarming the first time it happens at a stoplight or when you are idling at the store it is very normal.
A full cooling cycle occurs from the time that the unit kicks on to the time that the temperature you set at the thermostat is reached and the unit kicks back off again. Its fairly quick and sporadic. Ac compressor is an important part in the car s air conditioning system. I added just a quarter can of refridgerant to it just in case it is low to see if it alleviated the situation.
I didnt want to add more in case i.
