13.1.1. Relationship between the condition of the air conditioner and pressure and

electric current

Cooling Mode

Condition of the air

conditIoner

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.

13.1.2. 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 has a humming sound.
