I have a Whirlpool Gold, bottom drawer refrigerator
that I am having some trouble with. Model #: GB2FHDXWB01, SN: K02889215
I apologize in advance for my lack of proper terminology. Last week, I had a problem where the bottom of the freezer
was filling up with a sheet of ice every day or so. I assumed this was a problem with the drain that the melted ice flows through into the drip pan so I took the freezer apart to access the drain. I had to remove everything in the freezer to access the back wall and once I got that back panel removed, I found that the drain was filled with ice. I cleared the ice with a blow dryer until I could shoot a little hot water down the tube with a turkey baster. Once the water all drained and the ice was all melted in the tube, I pulled the rubber nipple off the end of the tube from behind the fridge, and noticed that there was only a little tiny razor blade thin slice in the nipple to let the water pass. I also found a little piece of fuzz in the nipple and assume that it stared the ice dam I was dealing with. In a moment of weakness, I opened that hole up in the nipple so that you could see light through it and put it back on the tube. I put the freezer back together and had it down for about 4-5 hours total with the power off.
My problem now is that the fridge isn't getting cold without turning it up to 6. I ran it at 4 for the 2 1/2 years I've owned it and never felt the need to turn it up any higher. It just isn't getting cold like it was before I defrosted that freezer drain. I ran it for about 12 hours before putting any food back in it. Everything that I put in the fridge spoiled before I noticed there was a problem. I have nothing but some canned drinks in there to monitor the temperature right now. I turned it up to 5 a couple of days ago and noticed that it did get a little colder. I went to 6 last night and it is fairly cold right now but I'm sure there is still something wrong with it and before I fill it up with food again, I want to repair it properly.
I took the day off from work tomorrow to tear it down again and see if I didn't seat the plug that I unplugged to remove the back panel but I doubt it's loose. I would really appreciate any suggestions anyone could offer because I'm completely lost around appliances. I would also be really interested in seeing a schematic on my refrigerator if anyone has one available. I have all the tools to tear it down and I do have a nice fluke multimeter handy.
