Troubleshooting
Evaluation of Abnormal High Pressure
Abnormally high pressure level is mostly caused by the condenser side. The following contents
are provided by service engineer based on their field checks. Further, the number is listed in the
order of degree of influence.
In cooling operation
In heating operation
Check No.6
Check items (Possible causes)
Judgment
Does the outdoor unit fan run normally?
Visual inspection
Is the outdoor unit heat exchanger clogged?
Visual inspection
Is there clogging before or after the EV
(capillary)?
Check if there is a temperature difference before
and after EV (capillary).
Check if the main valve unit of EV operates
(by noise, vibration).
Is the check valve clogged?
*Heat pump model only
Check if there is a temperature difference before
and after check valve.
→
If YES, the check valve is caught.
Is the HPS normal?
Check continuity by using a tester.
Is the outdoor unit installed under such
conditions that short circuit easily occurs?
Visual inspection
Is the piping length 5 meters or less?
Visual inspection
Does air enter the refrigerant system?
Conduct refrigerant collection and vacuum
drying, and then add proper amount refrigerant.
Is the refrigerant overcharged?
Conduct refrigerant collection and vacuum
drying, and then add proper amount refrigerant.
