The ice box only holds around 4 ounces of freon. So any leak and you would know it immediately. You can bubble test suspect areas for leaks. A tiny pinhole leak is hard to detect so it may take years for you to have to add any more. A severe leak would be easy to spot. Leaks occur where brain dead manufacturers place the tubing in a water pan or too close to the defrost heater.

So that should give me an idea of where to look for the leak then.  So, in order to fix that problem completely I would have to replace the tubing then recharge the fridge?

No tubing replacement. We are talking tiny leak here at the most. You either solder the hole closed or use epoxy putty to seal the leak. Then you evacuate the air out of the system to prevent ice from blocking freon flow. Then you very slowly add small amounts of gas till all the coils in the evaporator are frosted over or 4 ounces whichever comes first. You want 5 PSI on the suction side, any more than that and she ices up on the tap or chokes down.

Extremely helpful information JW.  Thank you for your knowledge I have a hard time getting people who have trades like this to give me any real knowledge about their trade.  They act like they are the only people in the world who can possibly understand what is going on with it, or just do it themselves; which I kind of understand.  But, anyhow I really appreciate it.
Hey JW, can I get your thoughts on something?  I am 25 yrs old and have some knowledge on repairing appliances, but, have a huge willingness to learn.  How would an entry level guy like myself get job doing repairs?  Any good tips? This is something I really want to do and have been working at it for almost a year now.  First appliances installs and now working independently trying to learn repairs.

If I was you I would go to trade school. You will probably get a job faster while in school than just jumping from job to job. Today's appliances are way more technical than old school appliances of the past. Or you might want to hang around here and ask questions. What we do here is trade off ideas. If you see something useful to tell you pass it along and we all gain from it. Instead of withholding info it freely flows from this site and all of us benefit from it. Their are guys in here that have been around forever and guys in here that are still in school and all in between.

I have been looking into trade schools.  but, it seems like there is not much that offers appliance repair.  The only thing I can find are 2 or 3 week courses that offer what seems to be useful information, but, I am not so sure that will get me a job doing repairs.

Just keep at what you are doing. We got plenty of service manuals on hand.
If you need a little help just ask.

Take pictures of the evaporators... the frost on the evaporator will tell you if you have a leak...But always check the condenser it must be able to release the heat.....post your question will help... just throw JW a beer how and then...

Love a cold one that is fer sure.  :pint1:

I was gonna do some video work. I made a 1 minute video of a window unit I hard wired to run without controls and it took fifty forevers to figure out how to do it and for it to take. I was figuring on making a video that would show how to but dangit I cannot even see it if a simple 1 minute video take 15 minutes to upload. Jeez. Maybe if I bought a better camera. LOL

Maybe a subject for a new topic. :)
