frigerant charged without vacuum purging.
(1)Clean condenser
(2)Check fan motor operation
(3)If (1) and (2) are normal,
check refrigerant amount
HINT: Vent out refrigerant
through gauge manifold low
pressure side by gradually
opening valve.
(1)Replace receiver and drier
(2)Check compressor oil to
see if dirty or insufficient
(3)Vacuum purge and charge
new refrigerant Drier in oversaturated state
Moisture in refrigeration
system freezes at expansion
valve orifice and blocks
circulation of refrigerant(1)Replace receiver and
drier
(2)Remove moisture in cycle
through repeated vacuum
purging
(3)Charge refrigerant to proper
amount
Excess refrigerant in cycle ±
refrigerant overcharged
Condenser cooling

cycle, but normal state is
restored after a time when the
ice melts
Pressure too high at both low
and high pressure sides
Frost or large amount of dew
on piping at low pressure side(1)Check heat sensing
tube installed condition
(2)If (1) is normal, test
expansion valve in unit
