• Carry out the measurement of pressure, electric current, and temperature fifteen minutes after an operation is started.
16.1.2 Diagnosis methods of a malfunction of a compressor
Nature of fault
Symptom
Insufficient compressing of a compressor
• Electric current during operation becomes approximately 20% lower than the normal value.
• The discharge tube of the compressor becomes abnormally hot (normally 70°C to 90°C).
• The different between high pressure and low pressure becomes almost zero.
Locked compressor
• Electric current reaches a high level abnormally, and the value exceeds the limit of an
ammeter. In some cases, a breaker turns off.
• The compressor has a humming sound.
