Why does my RV Refrigerator Smell like Ammonia?

Ammonia is used in your RV refrigerator because it requires less electricity to keep cool and is perfect for particular purposes. Years and years ago, ammonia was the main product used in all types of refrigerators but is now mainly found in vintage and special use fridges.
The main reason that ammonia is not used in residential refrigerators anymore is that it can present a considerable hazard if there is a large leak. Ammonia can be damaging to your eyes and skin, so make sure you protect yourself appropriately.
A leak within the cooling system of your RV refrigerator is the main reason you will be smelling ammonia when you open your fridge door.

How Do I Know if my RV Refrigerator is Leaking Ammonia?
While the smell of ammonia is oftentimes enough to alert your senses that something is off, there are a few other things you can look out for.
