Hopefully GE is still using 134a.

Sadly, the ban on R-12 I think was a plot to manipulate society, cause people to buy a "new" fridge, a new air conditioner, a new car, and part of a scam to condition society to believe the propaganda fed to them.
Now we've got that global warming crap shoved in our faces - another story built on fear and manipulation.
R-12 was the best cooling refrigerant designed.
Refrigerant industry changes have ZERO effect on whether I choose to buy a new refrigerator, A/C, or anything related. I purchase new items when replacement of the existing unit is justified on my need for it. I didn't research or ask what type of refrigerant was in the new heat pump in Jan 2022 or the refrigerator in Jul 2024. It was of no consequence to the decision.
Until you have to add refrigerant or need to replace any component of the sealed system.
I doubt it, but I could be wrong. My fridge is R134a, so I have a good reason to keep it in service as long as possible.

R 12 was mainly for automotive AC. R 22 was used in central home AC units and refrigerators. Dichloridiflouromethane.
I don't have the skills or qualification to do sealed system repairs ... that would be the service folks' job, not my concern.
Right, to which they would advise you buying a new machine instead of repairing an older one.
R12 was used in refrigerators and home ACs way back when. R502 was used in commercial refrigeration. Two exceptionally superior refrigerants.

I checked to see if there was a 12v version of that fridge-none found...
I have 3 minis active at the moment:
-GE from about 1990
- Brazilian WP,1999
-Haier from '06

My 1985 GE 18cf top freezer fridge owners/service manual states that it uses
5 3/8 ounces of R-12.
Not bad at all.
I remember some back coil condenser fridges that had 13.5 oz of R12. In all honestly I'd take extra R12 is it meant the fridge had a coil that essentially won't get dirty as fast and is easier to clean.
Amount of refrigerant in home refrigerators
Has nothing to do with whether it has a rear mounted condenser or one underneath or in the cabinet for that matter.
Brands that had rotary compressors like whirlpool and Frigidaire had a lot more R12 in them, they typically had anywhere from 13 to 19 ounces.
I have a 1961 Westinghouse refrigerator for example with a rear mounted condenser that only has 4 ounces of R 12 in it Westinghouse tended to use less refrigerant than many other brands. It has a piston compressor.
Hi Matt, what is the model number of your GE refrigerator you were saying for a while it was in 1987. Now you’re saying 85 that model would be right on the border of having a rotary compressor or not I’d be curious to know which one you have.

I'm not so concerned about "dates", however the manual that I have in my hand right now is a model TBX18ZLS
The label inside the freezer door says TBX18Z
Another number above the "specifications listing" is 203C2570P003
And the document's page is dated 12/89

I don't recall R12 in home A/Cs, but I certainly haven't seen them all... Sears put out a window unit with a cylindrical evaporator and condenser that sounded like a leaf blower. I can't imagine that in a bedroom! I have a vintage Universal upright freezer that I can't figure out what should have in it. The only marking is R22 stenciled on an air deflector by the condenser, but there's no mention of refrigerant type or quantity on the rating plate. I would have expected R12, but... I was utterly without success finding a word about it online.
Of course I know that... it just didn't make sense to me that was the kind it needed. I have a good bit of refrigeration experience, but no formal training. (you know, just enough to be dangerous!)
Very nice!
Thanks!
I have to admit this fridge is of good quality, for example the solder joints look well made.
Only thing I don't like is the compressor looks small and cheap.

The one thing I'm critical about are printed circuit board Solder Connections!
If I notice a thin "starved" coating on a board, it's due to poor Quality Control of the Wave Soldering Machine's Setup. (not set for proper flow of solder or board speed)
We call this a "Dry" board, and will eventually result in components breaking free under stress.
Things like vibration, repeated heating/cooling of components, resistors, etc., all cause mayhem or failures.
Inspection with a magnifier will show what we call "ring joints", where the wire/component lead will have a circular "break" on the pad, or blackening around the pad due to arcing.
Yup, I agree. Mini fridges are one of the last bastions of electronic-less design. Here is the circuit diagram to a nearly identical GE branded mini fridge. Only thing present are spade and crimp connectors. There are absolutely no soldier, circuit boards, thyristors, capacitors, read outs, thermistors or undersized relays to fail.
All you have is a master off switch in the thermostat, a light switch, a temp cycling switch, a klixon and PTC resistor. Bulb and compressor of course. Nothing to go wrong.
There was once a time when full sized fridges were literally built exactly like this. Then they added a SPDT synchronous timer for defrost. Everything was still ok until they began adding circuit boards for adapted defrost. And then that board turned into a main control board which did everything including sensing temps. Then they began adding dampers and variable speed fans. Now they're moving variable speed 3 phase compressor down the line.
It won't be long until mini fridges begin have pricey control boards that are one part self diagnostic computer another part IBGTs for a variable speed compressor. Motors, dampers, solenoids, thermistors, humidity sensors, and who know what else complicating an incredibly simple, once perfected function.
