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.
