Yes ,i know what is this alarm ,but what can i do now to solve the problem?

[Brian_UK]

Very hard to see from here what may be wrong.

Only guessing at what might be running at the time so I'm going pick a faulty fan motor or maybe a refrigerant leak.

I would suggest that you contact a refrigeration company to investigate the problem and advise on remedial action.

I check motor temperature during work,it is over 100 degree.We add ref 134A but again we have alarm 131.

I change the fer.134A and add new with factory value 60kg for this circuit ,and also we change the filters ,but after this service again we have same alarm 131 .

On circuit 1 have 6 fan motors command with 3 relay ,i change to operate relay 1 in same time with relay 2 and relay 3 to operate with signal from relay 2.Now is good but ones in the day we have again alarm 131.
