Symptom
Electric current during operation becomes approximately 80% lower
than the normal level.
The discharge tube of the compressor becomes abnormally hot
(normally 70~90
).
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.
The compressor has a humming sound.
