Hi All,
I have a DR1 Monitor Top that I purchased back in the 90s which ran and cooled perfectly. It showed almost no rust or corrosion anywhere on the condenser, float chamber or evaporator. I fired it up this past week and the compressor started right up and runs smoothly.. I get very little to no cooling at the evaporator. I did place some boiling water in the evaporator and it cooled it down only to ambient temperature. As it runs it will run smooth then from time to time the compressor softly rattles for a few seconds then clears up. I turned it off and put a 100 watt light bulb inside the box closed the door and let it stay in there over night. From time to time before bed I placed a stick of wood on the float chamber and I heard bubbling & gurgling so I know that there is liquid SO2 in the unit When I tried starting the compressor the next morning, the condenser coils reached 90 degrees and the evaporator went up to 90 degrees. Knowing that there is refrigerant in this unit, I am not suspecting that any has leaked out do to the rise in temps on the condenser coils and evaporator coils. Also periodically through the years, I would open the door of the box and never once smelled even the slightest trace of SO2 when I opened the door. I have tried rapping the float chamber with a rubber hammer but to no avail. The suction line at the evaporator will only go down to 68 degrees with the condenser coils at 90 degrees. I am fairly sure that the float is stuck and as a last resort I want to try using a fishing magnet to lift the float. Has anyone had any luck with this method ? Any help or suggestions will be greatly appreciated..
