hi guys.

im have been in the air conditioning trade for 9 years now mainly doing installs on vrvs and split systems.

today i got asked to look at a climaveneta chiller which feeds a big shop in a shopping centre <1 of many>

when i got there on the control panel it says 'compressor high pressure alarm'

there was no way of runnig the system until the fault is rectified. coils are clean and so are filters fan motors seem good. i didnt want to go any further as i am not confident enough and didnt want to balls it up even more.

i woud really like to know what could be causing this as i hate being defeated could anybody please shed some light on what could be causing this fault.

many thanks
