Hello fridges
I have a mission electric suz-ka71va3 cassette. Fault code UF . Compressor over current. Compressor runs for 5-10 seconds draws 12 amps. Then cuts out.Removed cables from inverter board u,v,w had 78 79 and 78 volts to compressor. I think it is the inverter board any ideas. 240 volt supply. Compressor measured ok.

compressor max current 8 amp on 240v supply- inverter pcb should put out minimum of 170v ac - so looks like its inverter pcb faulty- check dc voltage on + - terminals should be 280-370v dc
