Here ya go "
The ideal freezer temperature is 0 Fahrenheit (-18 Celsius) for storing food. And -10 Fahrenheit (-23 Celsius) is recommended when freezing food.


For every five degrees Fahrenheit above zero, the recommended storage time is cut in half. Food stored above 0 Fahrenheit loses more nutrients and loses quality faster than properly frozen food.




The faster food freezes the smaller the ice crystals. The smaller the ice crystals the smaller the change in texture and better quality when thawed."

Meanwhile the reefer box should be held around 34F if possible.

I find the tube being partially clogged a interesting problem in itself. . Also I have done a dollar bill check the gasket thing, it's o.k. I'm a hvacr licensed tech. but ammonia systems intrigue? me, if that's the right word? SOOOO... anyway, I ran it on gas...now at -2 freezer, 36 fridge... with thermister hooked up. I guess the electric elements weak?

I've never heard of a partially failed calrod but maybe. Certainly the gas has much more "power". I attach a very good primer on Ammonia system. Basically it uses a small flame for heat compared to the heat of compression real reefers use. You'll have a much better understanding of these systems. Written years ago by Dometic for aid in trouble shooting their systems. I think Fred Flintstone had something to do with Ammonia development. Hope its useful to you. They may even discuss how the tubing can plug with rust and components of refrigerant break down.

Well, changed out the element and all is well. temps are down ehere they belong, actually same gas or electric. Thanks for the education on ammonia systems, simplicity at it's best. Sure different than dealing with seer18 a/c!
