The pressure switch is part of the air conditioning in the car. When the air conditioning is on, cold air is supplied. To accomplish this process, refrigerant gas is compressed by the air conditioning compressor. This involves extremely high pressure. As soon as the refrigerant of the air conditioning has reached the desired temperature, the air conditioning compressor is switched off. If the air conditioning compressor was not turned off, the pressure would rise so high that the air conditioning system would eventually burst. To ensure that this does not happen, the pressure switch is installed. This switches the system off as soon as the desired temperature is reached and ensures that the pressure does not rise too high.
Air conditioning pressure switch broken
When the pressure switch of the air conditioning is broken, this will be noticeable from the air that is blown into the car. In the event of a faulty pressure switch, the air that is blown into the interior will no longer be properly cooled. Sometimes there will even be no cooling at all. In most cases, a pressure switch will fail due to rust or corrosion on the contacts of the sensor. In addition, the switch can break due to vibrations from the car or dirt in the air conditioning hoses. You can try to free the contacts from rust, this could cause the pressure switch to work properly again. Doesn't this help? Then it is important to replace the switch.
Replace air conditioning pressure switch
The difficulty of replacing the pressure switch depends on the make and type of car. On some cars, the air conditioning system will first have to be emptied. However, this is not the case with most vehicles. Also, the seal ring will have to be replaced and it is sometimes necessary to replace the contacts or terminals for proper functioning of the new pressure switch.
