Could be , but its not. Those evaps are bad for leaking.Pump it down and recharge it and add some dye. I had one about 6 months ago.561 I think.

As you probably know the points where is leak is most likely to occur is where the heater meets the evaporator. Look for signs of oil residue around that area.

I never found any oil on the last one I had. And after dye it took about 5 to 6 weeks before customer called . Not cooling again , never did pin point the leak , but it was in the evap.

Proper leak detection with refrigerant and dry charged Nitrogen. Thank You.  O0

I use a halide torch to look for leaks. Not a big fan of adding anything other than oil or refrigerant.

Ah a man who is after my heart. Good old Halide torch.
True story. Years ago my dad was installing a showcase on Madison Ave. in NYC.
Dupont salesman had just convinced him how great Methyl Chloride was so his helper grabbed the Halide Torch to look for leaks. Ironically the kid happen to turn his head when he lit it and BOOM The kid my father,salesman and showcase wound up on the other side of the street.  :rofl: :rofl:

Better update Whirlpool on that. Those nasty dye dryers. They even come with the compressors. GE is the only one that says add nothing to the system that I know of.

I have used Superseal on systems with a leak I could not find and even on  systems that the customer would not spend what it cost to repair..and have not had a call back on them..

I have put on many dye dryers not had any trouble with them..

I found it ... it was a leak.. It was at the copper to aluminum tubing at the evaporator, the tech before me over heated the tubing ... He must have not protected the tubing well ,,, I use heat paste and a wet rag to keep the heat off it.
