I have a side by side unit model PSC25PSTA SS, with the dual evaporators, which it seems that from the time the warranty expired, builds up mold all over the inside of the refrigerator section. It also builds up enough water condensation, that it actually leaks out the bottom of the door, enough to cause damage to our floor. We have to keep a rag laying on the bottom, to absorb the moisture, and is changed regularly, around every three to four days. I have the temperature set to 0 on the freezer side, and 37 on the fridge side. The temperature display is almost never at this setting. Most of the time the temperature is 10 to 14 degrees higher than the settings, on both sides. The freezer has an automatic ice maker, which every few days I have to break up the ice in the tray, since it looks like it has melted somewhat, and solidify all together into one giant blob of ice. The same thing happens to the ice cream.
About two years ago, I downloaded the service manual from this site, ran the diagnostics, and everything checked out, including the thermistor resistance measurements. I read about a similar problem a lot of people were having with these profile's units, and the suggestion was to replace the mother board which I did, but to be honest did not really help.
I suspect two issues are at play here. The first one has to do with the internal programing of the temperature control cycle, which in order to get a favorable energy star rating, the control program runs it as little as possible, with the widest temperature spread they can get away with. The second could be the defrost cycle running too long, heating the interior too much, and overwhelming the cooling system. These are just theories, and would like to know if anyone has heard this from any of the GE techs?
If anyone has any suggestion on how to rectify this problem, even if I have to run the stupid thing all day, I will, because is either that, or just get a new refrigerator, but I can tell you, that it won't be a GE product!
