How do I know if my gas refrigerator is leaking?
When a unit rusts and leaks as a result, the ammonia gas is lost first. You can sometimes smell the ammonia gas. However when the door is opened or if the leak is small there can be little or no smell. Under these circumstances there could be a boiling sound at the back of the refrigerator. This means the hydrogen gas has also leaked out and the water is now boiling. Ammonia smells or large gurgling sounds from the refrigerator are indicators that the refrigerator cooling unit is leaking.
