The low pressure reported by the compressor unit can be caused by a variety of factors:
Insufficient refrigerant or leakage: This is the most common cause of compressor low pressure alarms. Refrigerant is an important substance to maintain the operation of the compressor, when it is lacking or leaking, the cooling effect of the compressor will be reduced, and even the phenomenon of low pressure will appear.
Electrical faults: Electrical faults can also cause the compressor to underpress. For example, low current, faulty capacitors, or blocked lines can affect the normal operation of the compressor.
Damage to critical components within the compressor: Some critical components, such as sensors, electronic expansion valves, solenoid valves, etc., may also cause compressor low pressure alarms if they fail or are damaged.
The ambient temperature is too low: In the low temperature environment, the cooling effect of the compressor will be reduced, and when the temperature is too low, the compressor is prone to low pressure.
Power supply problems: The supply voltage is too low or unstable and may also trigger a compressor low pressure alarm.
Refrigeration system overload or short circuit: Problems such as overload or short circuit can prevent the compressor from working properly, resulting in low pressure.
In order to solve the problem of compressor low pressure alarm, these possible causes need to be investigated one by one. For example, check the amount of refrigerant, check whether the refrigeration circulation pipeline is normal, check whether the power supply voltage is normal, etc. During troubleshooting and problem solving, stay calm and follow the appropriate safety regulations. If you are unable to resolve the issue, please seek help from a professional technician.
