Question about Refrigerators
Many recalls for both dometic and Norcold have been issued in the past.There is a chemical called sodium chromate in the solution that circulates inside the cooling unit. It is there to prevent the ammonia/hydrogen/water solution from corroding the steel tubing. If a leak develops, this chemical changes from a liquid state to a powder in the presence of air. A yellow / green residue on the outside of the cooling unit indicates a leak. And the cooling unit is bad....... Also if the unit sat for a long period of time UNLEVEL then you could have blockage,the refrigerator depends on gravity to move the solutions through the system once the heat source has lifted the solutions to the top of the cooling unit. The passages that the solution must travel through have only a slight slope to them and any off-level condition will hinder this gravity flow.I would rather advise you to call the manufacturer and check if there is any recall. Unless, they could tell you the quote to change the cooling system. You could take a decision from there. A thumb rule - if the cost of the repair is more than half of the cost of the product, it is wise to switch to a new unit.
Let me know,if needed further assistance.
