While you have rearranged the Ammonia. That is what happens by burping. You have NOT removed any blockage if you have one. IF you have a blockage, NOTHING can remove it. It is as hard as a weld and is welded to the upper interior tube. Burping allows the Ammonia to settle in the correct bottom area. To see if you have fixed the problem will take a few weeks or months. We you bypass a blockage and burp, the refer will start to work. The freezer is NEVER affected by a blockage. Just the Lower section. Usually after a few weeks or months the refer will slowly NOT cool correctly in the lower section. Especially as it gets warmer ambient temps. Now, if you have NO blockage, odds are your problem was caused by a lack of ventilation or running off level. When this happens, turning the refer OFF and just driving for 30 minutes or so will accomplish the same thing as burping. Then you restart and then refer returns to its normal operation, which is what I believe has happened to you. Doug
