and pull a vacuum. turn unit on compressor came on but suctio
pressure went into vacuum. i check for air flow restriction non
recheck all lines no crimps. Please help :confused: :confused:
It is possible that some of the fittings were not tight enough and some
of solder flowed into the piping.
What filter drier did you change? If there was one in the condenser, did
you remove it and put a new filter drier on the liquid line?
If solder got in the refrigerant lines it could have lodged in the
screen ahead of a TXV valve or other type of refrigerant control.
Look and feel for a cold or frosted area on the liquid line all the way
to the metering device which indicates a restriction.
Study everything on Air Conditioning that you can find!
