Dear All

The BCU of my 600 NMR with CP has a problem to provide the cold air. I opened
it and found the fan was working fine and the compressor was hot and there
was no any ice. We only used it 1-2 weeks each year, but the new one is very
expensive around $17k. I guess that there is low pressure refrigerant.
Dose anyone have any suggestion of the replacement or the repairing?

Thanks,
Tianzhi
