OK-- First I had puddles under the front of the fridge--- then it stopped keeping milk fresh so I bought a thermometer.
The refrigerator section was warm, so I checked the freezer & found the coils in a block of ice. [literally-- the right side was a block of ice-- the left was 2" thick with frost]
Great, I think-- and defrost the thing with a hair dryer. I didn't remove the galvanized pan behind the coils, but I could see that there was ice there, so I continued to apply heat until there was no more dripping.
After all is warm & dry I plug the fridge back in. The best the refrigerator seems to do is about 40 degrees. I can hear the compressor going nonstop, but there isn't even enough cold to kick the icemaker into action.
A thermometer in the freezer shows 27-8 degrees.
I pull the fridge out to check the compressor fan-- it is working fine & isn't too dirty. Clean and replace.
Unclog the drain tube.
Then I pulled the compressor out of the bottom & clean the coils.
Reassemble & plug it in. I can feel a hot & cold side to the pipes coming out of the compressor, so it is running-- but I still only get 26- degrees in the freezer section & it sounds like the compressor just runs continuously. [it is hard to tell because it is so quiet-- does the compressor fan only run when the compressor is running?]
I just went back & felt the tubing again. The cold side, which was very cold when I first plugged it in, is now just barely colder than room temp. [but the compressor is still running.]
Am I to the point where I need to call a pro or is there something else I can check?
Is this thing worth charging if that's what it needs?
