First off, Ammonia fridges don't slowly die. they die from the ammonia solution leaking out from corroded piping and if they 'spring a leak', you'll know right away because one, you will smell it and two, you'll see it. The solution as it leaks will leave a yellow stain (usually around the lower part of the boiler, which is the sulfur in the refrigerant solution. That is a rare thing.
Ammonia fridges CAN die a slow death....without ever leaking
Off level operation disrupts the gravity flow of coolant, that causes overheating issues, sodium chromate crystallizes (anti-rust inhibitor---yellowish residue when a leak occurs).
The crystals plate out on inside of tubing causing more overheating, more plating etc.
Damage is accumulative......slowly dying cooling unit
20 minutes off level can cause this......
