It will KILL a fridge cooling unit.
By "kill", do you mean kill forever and never recover?!
YES...
The Sodium Chromate (rust inhibitor in coolant solution along with ammonia, water & hydrogen gas) will crystallize when overheated and those crystals plate out in inside of cooling unit tubing....creating a restriction which disrupts the natural heat process and gravity flow.
Restriction creates more opportunities for overheating conditions which causes more formation of crystals/more plating out/more restriction-obstructions ---process is accumulative and permanent.
Sodium Chromate is 'yellow' when dried,,,,,so if you see yellowish residue down around burner area.....DEAD. Cooling unit has leaked
But a leak doesn't have to happen ----tubing can become so blocked that NO Cooling takes place ....again DEAD.
So when stationary ...FRIDGE LEVEL if turned ON
(comfortable...no noticeable tilt/slant of RV)
When in transit/in motion the rocking, bouncing, movement of RV will keep the coolant solution in motion and not a big concern to operate fridge while traveling.
