What are the signs of insufficient compressor compression in a Panasonic CS-C18HKQ Air Conditioner?

  Jeffrey LawsonJul 29, 2025
  If the electric current during operation is approximately 20% lower than the normal value, the discharge tube of the compressor becomes abnormally hot (normally 70 to 90qC), and the difference between high pressure and low pressure becomes almost zero, it might indicate insufficient compression. The suggested solution is: Electric current during operation becomes approximately 20% lower than the normal value. The discharge tube of the compressor becomes abnormally hot (normally 70 to 90qC). The difference between high pressure and low pressure becomes almost zero.
