Questions and answers
Water pools on the floor overnight when frige is on gas
Water pooling on the floor overnight when the Thetford N304.3 fridge is running on gas could be due to excessive frost buildup in the freezer or on the refrigerator fins. This can occur if food storage containers are not sealed, the refrigerator door is opened too frequently, the door gasket does not seal properly, or the refrigerator and freezer are not defrosted. When the frost melts, it can cause water to leak onto the floor. Checking and addressing these factors can help prevent water accumulation.
