Whilst working alongside the Fujitsu unit I noticed almost totally blocked outdoor fins so had a look at the inside which is the model listed,don't think I've seen a dirtier filter!Cleaned filters whilst testing the unit I had repaired and restarted it but no compressor run.Didn't have the time to check any further but is there an overheat trip on these that might have operated,the outdoor fan is running .
Cheers
