Auto Air Conditioning Compressor Cycles On And Off

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.

Auto air conditioning compressor cycles on and off.

In simple terms an ac compressor is a pump which creates the heat by putting the air conditioning refrigerant under extremely high pressure. In the words of many repairmen an ac compressor is the heart of an ac system. Air conditioner short cycling occurs when something within the system prevents your unit from completing a full cooling cycle. Pressure on low side ranges from 35 45 psi.

There is no pattern to it. The air conditioner compressor was rapidly cycling on and off. Ac compressor is an important part in the car s air conditioning system. 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.

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. 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. 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. I didnt want to add more in case i.

Is your air conditioning system turning on and off right away after only a few seconds or minutes of running. 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. Regardless if idling or driving the a c compressor clutch cycles on and off constantly. Air conditioner short cycling simplified.

I added just a quarter can of refridgerant to it just in case it is low to see if it alleviated the situation.
