Water dripping underneath the RV (right below fridge)

Drain tube is plugged up. When the fridge defrosts, the water accumulates in the tray on the inside of the fridge. From there it dribbles out into the tray in the outside fridge compartment. It's then supposed to drain out thru the hose to the outside. Remove and/or flush both lines and your 'issue' will go away. Dennis
