RV Refigerator Tip
Don contributes ...
Let me share this tip with you from a local RV dealer. He recommends that you put a single ice cube in a paper cup and leave it in your freezer and check it daily to be sure there had not been a power failure at the campground while you were away for the day, or that nothing else has happened to cause the frozen foods to partially thaw and re-freeze again.
If the freezer has been working well, the ice cube should retain it's original shape. If it has melted and re-frozen the ice will be puddled in the bottom of the cup and chances are that the quality of your food in the freezer and refrigerator will be comprised.
I always find your tips helpful. Thanks keep up the good job!
