Hello
I have a little problem with this compressor.
the controler shows high discharge temperature.
What can be possible failures

What are the operating conditions? what is the refrigerant?

Hi Mikseidis.
There could be many reasons for your High pressure Fault.
If the tranducer is reading correctly.
The speed at which you observe the HP rise from start-up would be a good indicator.
Also is this a stand alone system or 1 of several. etc.

In no particular order
lack of HP cooling, Cond. water / air?
overcharged? (unlikely unless you have adjusted the charge).
Air in the system?
chocked liquid strainer?
Condenser scaled or dirty?
Moisture in the system?
Faulty Expansion Valve (closed)?
For example!
Cheers Grizzly.

For a better answer give us more info!
