ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
HINT:
This is a method where a manifold gauge set is used to help locate the problem.
(a) Read the manifold gauge pressure when the following conditions are met:
Test conditions:
(1) Normally functioning refrigeration system Gauge Reading
|
|
(2) Moisture is present in the refrigeration system.
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
During operation, pressure on low pressure side cycles between normal and vacuum |
|
|
|
(3) Insufficient cooling
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Gas leaks from the refrigeration system |
|
|
(4) Poor circulation of refrigerant
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Refrigerant flow is obstructed by dirt inside the pipes of the condenser core |
Receiver is clogged |
Replace condenser |
(5) Refrigerant does not circulate.
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
|
Refrigerant does not circulate |
|
(6) Refrigerant is overcharged or cooling effectiveness of condenser is insufficient.
Symptom |

(7) Air is present in the refrigeration system.
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Air in system |
|
|
(8) Expansion valve malfunction
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Expansion valve may be stuck |
|
Check expansion valve |
(9) Insufficient compressor compression
Symptom |
Probable Cause |
Diagnosis |
Corrective Action |
---|---|---|---|
|
Internal leak in compressor |
|
Replace compressor |
