Low Pressure Switch Air Conditioner

So you do often have two different ac refrigerant pressure switches on your car.

Low pressure switch air conditioner.

However remember the important role in managing the pressure of the refrigerant as it works through the ac system that the ac pressure switches play. The low pressure switch turns the system off when the pressure is too low to prevent damage to the compressor. The a c pressure switch is mounted on both the high and low sides of your a c. Air conditioning pressure switches are designed to protect the a c system against pressure that is too high or too low.

It monitors the pressure of the refrigerant on its respective side of the system. If you jump the low pressure switch with the engine running do it only for a few seconds. There are both high pressure and low pressure switches. R p m of fan coil blower too low.

Fan coil motor is rotating in the reverse direction. Temperature setting of thermostat too low. Some vehicles are equipped with just a high pressure switch while others have both. One on the low pressure side before the ac compressor and one on the high pressure side.

Fan motor belt loose or slip. Ambient temperature too low. Low pressure switch cuts off air conditioner troubleshooting. Like all parts of your vehicle it has a limited lifespan.

Incorrect pressure can damage the compressor hoses and other a c system components. The ac pressure switch is a safety switch that is mounted on both the high and low sides of the air conditioning system. Refrigerant does not wear out or evaporate. This means that if one or even worse both switches are failing then the ac system will be receiving incorrect pressure readings from either the high or low side of the system.

This protects the compressor from damage. Jump the low pressure switch only to test the circuit. 90 get it as soon as fri sep 25. Duct resistance too high.

Do not jump the low pressure switch to operate the compressor non stop so you can add refrigerant.

Only leaking air conditioning systems have low refrigerant levels. 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.

If you are suffering from problems like an intermittent response from the ac unit when you turn it on a lack of cooling or an outright failure of the system then the problem. Duct damper is closed. When the pressure in your a c rises or lowers too much this switch turns off the compressor to protect it and the rest of the system from damage. There is a high side pressure switch and low side pressure switch and they both serve to monitor the system for pressure faults that can.
