Car Air Conditioner Compressor Kicks On And Off

The aircon can switch itself on and off intermitantly when you have a faulty resistor pack thermostat faulty track on your accelerator position switch faulty hot cold control faulty system pressure switches compressor clutch or associated relays and wiring.

Car air conditioner compressor kicks on and off.

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. This can cause severe damage to your unit so if you notice a refrigerant leak this should be serviced right away. The air conditioner compressor was rapidly cycling on and off. 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.

This coolant is crucial for absorbing heat and cooling air so when there is not enough of it the compressor pressure levels become unstable causing it to turn on and off repeatedly. Air conditioner turns on and off right away. The compressor can only work so hard though and when it reaches the maximum it can work it will kick off. In simple terms an ac compressor is a pump which creates the heat by putting the air conditioning refrigerant under extremely high pressure.

The way to go is an aircon system scan to isolate the electrical fault s. Is your air conditioning system turning on and off right away after only a few seconds or minutes of running. 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. If it is doing so rapidly though it can indicate an improper charge such as being low on r.

This will cause the air being blown out of your car to get hot. Also when you have too much refrigerant in the system it will cause the system to have more pressure and this can again lead to issues with the compressor. 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.
