Low Pressure Switch Air Conditioner

This protects the compressor from damage.

Low pressure switch air conditioner.

Some vehicles are equipped with just a high pressure switch while others have both. 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. If you jump the low pressure switch with the engine running do it only for a few seconds. Do not jump the low pressure switch to operate the compressor non stop so you can add refrigerant.

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. It monitors the pressure of the refrigerant on its respective side of the system. Low ac pressure will prevent the relay from sending power to the ac compressor clutch. Fan motor belt loose or slip.

Only leaking air conditioning systems have low refrigerant levels. Ambient temperature too low. Duct resistance too high. The low pressure switch turns the system off when the pressure is too low to prevent damage to the compressor.

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. This switch is crucial for proper a c performance. Fan coil motor is rotating in the reverse direction.

So you do often have two different ac refrigerant pressure switches on your car. Air conditioning pressure switches are designed to protect the a c system against pressure that is too high or too low. 90 get it as soon as fri sep 25. Low pressure switch cuts off air conditioner troubleshooting.

Incorrect pressure can damage the compressor hoses and other a c system components. Like all parts of your vehicle it has a limited lifespan. Temperature setting of thermostat too low. R p m of fan coil blower too low.

An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level. 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. The a c pressure switch is mounted on both the high and low sides of your a c. One on the low pressure side before the ac compressor and one on the high pressure side.

Jump the low pressure switch only to test the circuit. Refrigerant does not wear out or evaporate. The ac pressure switch is a safety switch that is mounted on both the high and low sides of the air conditioning system. Duct damper is closed.
