This morning I noticed the digital temperature in my fridge was at 50 deg F, but the freezer temp was still at 0. I let it be for a few hours, then checked it again, and the fridge temp was back down to 37, per normal. I checked again an hour later and it was back up a little above 50. I then started to investigate, as I know nothing about refrigerators. I observed that there is cool air entering the fridge through the upper vent, but no air is entering from the bottom vent. I also removed the bottom panel in the back of the freezer and noticed the evaporator coils had a good bit of frost on them, but they were evenly coated. I can hear a fan functioning in there as well. I decided to do a manual defrost anyway. After the evaporator coils were defrosted, the fridge temp still read above 50, and still no cold air entering through the bottom vent of the fridge.
I'd really appreciate some advice??
Quick update:
About 2 hours after the manual defrost, the fridge temp was still at 50. However, about 10 minutes after that, the temp started to rapidly fall and is now at 36, where it should be. I'd also like to state that I'm just assuming the what I called a "vent" in the bottom of the fridge is indeed a vent. Maybe it isn't, though. It is a rectangular opening with styrofoam on the inside.
I'm not very confident I've fixed the problem, or just gave a temporary solution. I'd love to know the root of the problem, and all advice is much appreciated.
After the manual defrost, the fridge has been working perfectly ever since. Do you think I'll just have to defrost every now and then, or is there a deeper issue, like the thermostat timer?
No, you shouldn't have to ever manually defrost it, it automatically defrosts on its own.
So either one of the doors was left open by accident for a long time like overnight or one of your auto-defrost parts is going out, your model doesn't have a defrost timer, its integrated in the display control board.
So keep your eye on it, and come back here if it does it again, then I will advise you to first force it into a defrost first to see if your defrost heater comes on, before you manually defrost it again.
