Hi Guy's
Was sent today to fit a small filter drier+capilary tube to a bottle fridge as previously diagnosed by another engineer.Fitted the parts,pressure tested,vac'd out system,recharged with 150grams of r134a.Powered up and was only gettin temp down to 14 degrees C.Checked pressures and the compressor was pumping itself into a vac...blockage somewhere right?The evap coil was still recieving refrigerant as it was frosting over near the capilary side.Surely the new capilary cant be blocked,i was very carefull when brazing it in as i know how easy it is to block them with solder.I did notice oil coming out of the evap when i removed to old capilary(this was at the top of the coil)could the coil be full of oil and this is whats stopping the flow of refrigerant?I'm going to have to go back tomorrow and remove all the brazed joints and blow through with ofn till i find the problem.
