If it is not functioning then the system can not operate and will be unable to produce cold air.
Ac compressor ac low pressure switch location.
One on the low pressure side before the ac compressor and one on the high pressure side.
The ac pressure switch plays such an important role in the operation of the ac system and yet is at the same time a component that is quite vulnerable to damage.
As the pressure switches control the on off function of the ac compressor a switch failure can prevent the ac compressor from functioning at all.
When it has failed or if it already failing it will therefore present with symptoms that are pretty easy to detect.
An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level.
In this article we will only be going through the ac low pressure switch s location.
The low pressure switch cuts off compressor specifically to prevent compressor damage due to oil starvation.
Let us find the reasons behind bad ac and the repairing process.
Compressor not coming on.
So you do often have two different ac refrigerant pressure switches on your car.
You might have to do some repairs by yourself to make it run correctly again.
You can jump three wire ac pressure switch to control the ac system as well.
Ac systems in vehicles run with a pressure switch.
In other words you can jump a low pressure switch in a car momentarily to make the ac compressor clutch engage for testing purposes only.
If you are not getting cold air when the thermostat is on and set to cool you may need to reset the compressor.
Switch on the high side line.
A c low pressure cutout switch sorry i wasn t really online much yesterday.
Refrigerant does not wear out or evaporate.
The ac pressure switch іѕ a ѕаfеtу ѕwіtсh thаt monitors the рrеѕѕurе оf thе refrigerant on the high and low pressure sides on your air conditioning system.
Central air conditioning systems have an outside unit with a compressor that runs and provides the cool air that runs through the vent system.
I d go by the wiring colors not where the diagrams state they should be.
Only leaking air conditioning systems have low refrigerant levels.
The ac low pressure sensor is located at the line that runs from the compressor component of the system through the evaporator or the firewall of the system up to the condenser on the low pressure side of the air conditioning system.
One might wonder how to jump 3 wire ac pressure switch by own.
And it makes more sense that the high line would have the hi pressure switch since you have a switch on it.
A c high pressure cutout switch switch on the compressor.
