SymptomProbable causeDiagnosisCorrective Actions

Vacuum is indicated on low pres-
sure side, and extreamly low pres-
sure is indicated on high pressure
side

Frost or dew is seen on piping on
both sides of condenser or expan-
sion valve

Refrigerant flow is obstructed by
moisture or dirt in refrigeration sys-
tem

Refrigerant flow is obstructed by
gas leak from expansion valve
Refrigerant does not circulate
(1) Check the expansion valve
(2) Clean out dirt on expansion
valve by blowing air
(3) Replace condenser
(4) Vacuum and supply proper
amount of new refrigerant
(5) For gas leakage from expan-
sion valve, replace expansion
valve
(6) When the refrigerant is overcharged or cooling of condenser is insufficient:
SymptomProbable causeDiagnosisRemedy

Pressure is extreamly high on
both low and high pressure sides

No air bubbles are seen through
sight glass even when engine rpm
lowers

(1) Clean condenser
(2) Check condenser fan motor
operation
(3) If (1) and (2) are in normal
state, check the amount of refrig-
erant and supply proper amount of
refrigerant
