If you are not getting your refrigerator
to cool correctly try a trick that was shown to me a number of years ago by an RV refrigerator
repair guy. I have used the trick on a number of friges and more than 80 percent of the friges come back to life. As it was explained to me over time the little passages in the fridge
gets clogged up. The repair guy told me to take the unit out of the RV, and stand it upside down on a flat surface for two hours, Then lay it on the right side for another two hours, Then on the left side.. Then stand it up and let it sit for at least four hours.. Then put the AC voltage to it and see if it cools. It has worked for me. The RV repair guy even had a fixture that he would do this with. I understand that turning it let the blockage move away from the places it is holding up the cooling material. The system sounds kind of crazy but it works as I have talked to some other RV repair guys and they say for a cheap check if you need a new unit or not..
