13.2. Relationship Between The Condition Of The Air Conditioner And
Pressure And Electric Current
Cooling Mode
Condition of the air
conditoner
Low Pressure
High Pressure
Electric current during
operation
Insufficient refrigerant (gas leakage)
Clogged capillary tube or Strainer
Short circuit in the indoor unit
Heat radiation deficiency of the outdoor unit
Inefficient compression
•
Carry out the measurements of pressure, electric current, and temperature fifteen minutes after an operation is started.
13.3. Diagnosis Methods Of A Malfunction Of A Compressor
Nature of fault
Symptom
•
Electric current during operation becomes approximately 20% lower than the normal value.
Insufficient compressing of a compressor
•
The discharge tube of the compressor becomes abnormally hot (normally 70 to 90°C).
•
The difference between high pressure and low pressure becomes almost zero.
•
Electric current reaches a high level abnormally, and the value exceeds the limit of an
ammeter. In some cases, a breaker turns off.
Locked compressor
•
The compressor is a humming sound.
