Ad50uss is not producing water. Fan and compressor is running . Coils are not getting cold, is refrigerant low? Or could it have a leak? How do u check for refrigerant leak and how do u add refrigerant and...


Compressors have 3 or 5 tubes coming out of the can. Probably 3 in this case. The largest is the suction and the smaller one is the hot gas line. The 3rd is crimped and brazed over. The suction line should be cool or cold (no frost or ice) and the small one should be hot. Be careful of fans. Also, that small line is normally hot enough to burn you. If they are the same temperature, its either low or out of refrigerant (Very common), the liquid line could be plugged (Rare), or the compressor is not pumping (also rare). From here on, you need a compound refrigeration gauge and a line tap. An amp probe would be nice but not needed at this point. If you have an amp probe and the compressor is running and not pumping, the amps will be lower than the name plate RLA or FLA by quite a bit. The name plate should tell you what type of refrigerant it takes. 134A is the new standard but it could be different (R12). Knowing the right type is a must. I have seen compound gauges, line taps, and R134A in hardware stores but you can't add any refrgerant on less your sure no air has gotten in. If the pressure in the suction line matches up close to the ambient temperature when the compressor is off, it has refrigerant. With the gauge on the suction line, start the compressor. If the gauge drops into a vacuum of 25 inches or more, the compressor is probably OK but the refrigerant is gone. If the leak is on the suction side, there will be air in the system. The moisture in the air will freeze immediately at the metering device and it wont get cold. If it all leaked out its another whole process to find and repair the leak, evacuate the system and weigh in the proper charge. I hope this helps. There is a whole process for all of this. Let me know if you have the equipment. I'll get you through.

The fan runs good. Cool air comes out the front of the unit but it doesn't condense any water. Someone told me I need to add refrigerant. Does that sound possible?


yes,its entirely possible cause after 2-3 yrs they lose some charge,make sure you read the compressor tag for correct refrigerant

Coils icing


the unit either has dirty evaporator coils and this will make them ice up,or the unit is low on refrigerant/freon,try cleaning the whole unit of dirt and dust first,then you may need to install a saddle tap on the sealed system and add some refrigerant/freon as these systems seem to leak more often than other sealed systems
