Hi, everyone
Unit consists of 1 inverter compressor, and 2 on/off compressors, client used to hire another company (fujitsu dealers in my country fml), they have changed 9 compressors in ~2 years.
Compressor makes a ticking sound for few seconds, but doesn't start up. Replaced inverter board, but that didn't help either.
We took refrigerant samples and in the lab we found that there was a lot of non condensibles (air) in the system, piping diameters and lenght are ok, so we pumped down the refrigerant, changed a compressor,, filled system with nitrogen, vacuumed and put a fresh r410A in the system, all according to unit needs and pipe lenghts after a few days and tried the new baby.
Compressor worked well... for a minute. Then same symptoms happened. we checked pipes for clogging, everything seems to be fine.
Masters, any ideas why did the compressor was locked again after ~1 minute of work? :confused:
