NO
YES
Replace the low pressure
sensor (S1NPL).
NO
YES
Replace the high pressure
sensor (S1NPH).
NO
NO
Replace the relevant
PCB(s) (
2).
If the error recurs, replace
the electronic expansion
valve (refrigerant jacket)
(Y3E).
YES
Replace the electronic
expansion valve coil (Y3E).
Correct the abnormally low
pressure.
Correct the insufficient low
refrigerant condition.
Correct the superheating
operation.
NO
YES

of the high pressure
sensor normal?
NO
YES
YES
YES
Is refrigerant
insufficient?
NO
NO
YES
NO
CHECK 2
