If the solenoid valve coil is burnt, the hair film can not be opened. You can determine whether the solenoid valve is burnt by measuring the solenoid valve coil with a multimeter; the valve body of the solenoid valve is damaged, causing the membrane in the valve to not open. When there is a temperature difference between the inlet and outlet of the solenoid valve, it indicates that the solenoid valve is defective. Expansion valve damage: The expansion valve is one of the four major components of the refrigeration system and is an indispensable component. After the condensed low-temperature and high-pressure refrigerant flows through the expansion valve, it is throttled by the expansion valve and expands and evaporates at the outlet of the expansion valve to form a low-temperature and low-pressure gas-liquid mixed refrigerant, thereby taking away the heat in the system and forming a refrigeration process.
