Fridge Problem..frost on suction line, and cooling is not good

[hunted22]

Check if condenser is hot to touch at top (where line is coming from compressor) and at ambient temperature at bottom where it meet filter-drier and report findings. Also try to determine how much of condenser is at an ambient temperature.

the condenser temperature from compressor to filter goes like this..

%55-60 is REALLY HOT to hot.. %15 warm.. %20-15 ambient.. while the suction line near the compressor is as cold as the evaporator.. maybe colder.

Does technician, when he was changed compressor, changed also filter-drier? Also did he measured end vacuum with separate vacuum measuring instrument or he just vacuumed some time without measuring vacuum.

Yeah he did change filter, and installed a valve.

I wasn't around all the time after he finished welding.. but I recall him talking about using the manifold to measure pressure after vacuuming, and after charging.

I don't recall seeing a vacuum though.. what I understood from the portions I observed is that he welded everything and installed the valve.. then used the running compressor to vacuum itself.. but that is what I put together from what I saw.. is that even possible?

It looks like it is overcharged.




Did he weighed charge, charged from glass cylinder



or charged by monitoring only suction pressure?

Last is recipe for overcharging.
