314Have a focus inspection on the following area:
a. Each pipe union joint and valve connection.
b. All hose, especially near the pipe union.
c. Compressor shaft seal, front and rear cover, gasket, oil fill plug.
d. Area on the surface of the condenser and evaporator that is scratched, bruised or damaged.
e. Expansion valve inlet and outlet connection and temperature sensor element and the welding position.
3. Check the Refrigerant
Observing from the sight glass, you may understand the refrigerant status and analyze the possible faults:
