Heatcraft puts defrost Grassilin clocks in all of their medium temp condensing units unless its a beer cooler we dont hook to them mostly because the worst thing one can do is loop a contactor coil through one of these. Does anyone know why its bad practice?
I know it has been a long time since I have posted but the call never came back in, until last night. Unit was short cycling, so again, grab the gauges and pump just a little 404 in to rise the pressure. Then I noticed the suction valve was bubbling like crazy, tightened down the packing nut and it stopped.
I realize that 404 is a blend and there might be some issues down the road with refrigerant separation ( the proper term escapes me for the moment), but at least a leak was found, and yeah, no issues since that timer was reprogrammed, which I just eliminated it all together last night
