AdaptaPAK® Maintenance and Troubleshooting

6 - TROUBLESHOOTING - COMPRESSOR LOW SUCTION PRESSURE

SYMPTOMS

POSSIBLE ACTIONS

Low compressor
suction pressure

1. Lack of refrigerant

2. Evaporator dirty or iced

3. Clogged liquid line filter

drier
4. Clogged suction line or
compressor suction gas
strainers
5. Expansion valve
malfunctioning
6. Condensing
temperature is too low

7. Broken internal

compressor part

1. Check for leaks; repair

and add charge

2. Clean/Check Remote

3. Replace cartridge(s)

4. Clean strainers

5. Check and reset for

proper superheat

6. Check means for

regulating condensing
temperature
7. Fix component; repair
or replace compressor

7 - TROUBLESHOOTING - COMPRESSOR LOSES OIL

SYMPTOMS

POSSIBLE ACTIONS

Compressor
loses oil

1. Lack of refrigerant

2. Excessive compression
ring blow-by

3. Refrigerant “flood back”

4. Improper piping or traps

1. Check for leaks, and

repair; add refrigerant
2. Replace compressor
