Need freezer Recharge Education

[amdx]

I have 13 chest type freezers, a couple of upright freezers and a two Ice Machines having to do with my business. The freezers are not always in use, so are shut off until needed. I have one or two that will leak out if the are shutoff, so we no long shut them off, we either leave them on when empty or move items in from another freezer that we can shut off.

Question one)

Explain to my why the freezer will leak refrigerant when it is off but not on.

Question two)

Sometimes when I go to restart a freezer after it is off for a few weeks or month, it does not want to start. The breaker in the compressor just keeps cycling. Usually after enough time passes It finally starts and will run fine from then on. Why?

Question three)

I would like to get enough education to be able to add refrigerant when a freezer needs it. The electrical part I have a good handle on, I have gauges and have no problem installing a Piercing type Shrader Valve. I need to know how to decide if a problem is caused by low refrigerant, I'm not one to just do something because that's what I know, I want to troubleshoot and come to a logical conclusion.

Has anyone seen a good video that helped or a book that is focused on home freezer?

Help is appreciated.

I have a brother in law that does refrigeration and he usually fixes things when needed. He never charges me enough and I don't like to have him do it because of that.

Sorry, I can't give you answers. If you feel so guilty about his low cost; slip your sister a Benjamin.

or some free meals, or whatever.

does the system have a "service port"?

ie a Shrader valve like a tire air valve.

If not, it will be very difficult to refill yourself.

Why not ask those questions of the BiL?

A quote from his original post :

Apparently you need to read more carefully .

hmmm, yes you are correct

Fixing 17 units takes a bunch of pot roasts and tatters with carrots.

If there is a comunity college near you you may check to see if they have any night classes you can audit. You do not get credit or anything for them, but you only go to the ones you want. No need for a lot of the other classes , say the electrical part, if all you want to do is learn something specific.

There are lots of videos on You tube that tell alot about refrigeration and aircondition.

One thing to learn is the law about how to reclaim the gas. YOu can not simply dump it to the atmosphere like was done many years ago. Big fine if you get caught.

Look for the Montreal Protocol. I guess that your BIL could get the refregerant for you, but you really need to take the test and get certified to buy it. They don't care if you know anything much about the equipment, but need to know the law.

Some of them have a special proprietary fitting and I've had to buy an adap= ter from the refrigeration supply house in order to service them. Schrader = valves can deteriorate and leak. If a unit doesn't leak down when running i= t could be that the Schrader valve on the liquid line is being kept warm an= d oiled which can keep it from leaking. Shut the unit down and the change i= n temperature can cause the valve parts to contract thus causing a leak. Th= e O.P. really needs a leak detector to check all the service ports on his r= efrigeration equipment.o_O
