The FEA is a cap tube system, thus a "dry" system. Looks to me like passages and headers are scaled down to keep velocity up for oil return. Looking at the pictures that evaporator looks more like a flooded type than a dry type. Though maybe that is just a poor assumption on my part based on the header I see on one side? What is going on, on the other side opposite of the header? It's hard to see in the pictures. You may be right I wasn't thinking about the fact that some flooded systems do use a cap tube.

Remembering that R-12 is miscible with oil, I'm thinking oil return wouldn't be a problem as long as there was anything like a full charge of refrigerant. And that looks more like an accumulator than a header to me; I only see one refrigerant passage leading into it, and no parallel refrigerant paths anywhere on the evaporator. I can understand the bevel on the back of the shelf, but it looks like it has a bit of a "ski jump" curve leading up to the bevel; I wonder why they did it that way?

I've never seen the inside of the first type of compressor, although the terminals sure look familiar.
The second type was used for a great many years, and is basically a horizontal version of the scotch yoke compressor we're used to from SO2. It is, however, suspended by springs outside the compressor shell, instead of internally.
I would be willing to bet the reason the first style didn't stay around long was people were used to turning monitors upside down, and if you did that without remembering to lock the compressor down it would make a helluva mess, fall off of the springs and out of the cradle, bend and kink the tubing. And they would have still been under warranty (the next design was only a year later, wasn't it?) so GE would have heard about it big-time. There was a similar issue with some window air conditioners that came with a "shipping bolt" that you were supposed to remove and retain in case you ever wanted to take it out of the window; people "forgot", and the compressor fell out......

I posted this in another section before I ran across this thread.
I've got many questions but here is one I was fixing to address... I have three square top monitors they all work in one form or another. The fan on one has never worked for 25 years it's my only everyday box and and I was thinking about fixing it.. I know why now? My question is will it hurt or help the fridge work easier? Thanks

Thanks Reply posted to other post in General section: monitortop.freeforums.net/post/18238/threadThanks for your response and my response in below... LOL No troll I'm real and interested to learn.. I do have 3 FEA square top monitors.. I'll post a pic to prove it when I get them taken. Believe me it's been running 25 years without the fan and it's my everyday box. The reason I'm wondering about it I have one that's not getting cool and that's what got me thinking about my everyday box.. LOL So I guess I need to fix the fan.. You know what's funny I actually have two with the fans not working and one with the fan that works and that's the one that doesn't get cold.. LOL Go figure? I've really learned a lot here thanks for having me..

Do the fans have oil spouts? If so you could try to put 20 weight non detergent oil in it, let it soak and work the bearings back and forth. That is, if the fan is stiff.

I took the fan out of the one in my house years ago because it wasn't working and I was going to replace it and I never found one. The other one spins free but it doesn't work. I'm not sure why but I'm going to start checking. Here is a pic of the one that has been working for 25 years without the fan..

That's a nice looking unit you have there. Those compressors are tough. I didn't know they were that tough! You would think with such a small condenser coil that it would overheat.

Thanks for the kind words, Yes we love it and it's our only fridge.. It's amazing how much you can get in there.. You know after thinking about it. I still have a warm morning wood stove in the same room that I use to heat my house with but not anymore unless the weather is really cold.... Yes I agree that must be a tough compressor.. I am going to be on the hunt for a fan soon.

Looks like a dr2 cabinet it's setting on hopefully it lasts another 20 years .

I purchased my first FEA monitortop in about 2007. The label info was worn off and not knowing the model# or even the refrigerant it used and thinking the motor needed to be an exact replacement I contacted Monitortop.com from New York. When I inquired over the phone about a replacement motor the owner laughed and said they will work without a fan motor. He wanted me to mail the old motor to him and he would send a new one back. I ended up purchasing a new single phase motor locally. The second FEA I purchased was from a lady who sincerely regretted selling it but she could see a spike in her electrical bill whenever they ran the refrigerator. When I brought it home I found it too had a defective fan motor causing higher head pressure and thus higher amps/watts and run times. The door gasket/seal might have been leaking also.

;could see a spike in her electrical bill whenever they ran the refrigerator. When I brought it home I found it too had a defective fan motor causing higher head pressure and thus higher amps/watts and run times. Wow, it must really be significant to actually see it on the electric bill; normally they'd draw a pittance that's unnoticeable. Would love to see what a kill-a-watt has to say about a FEA with and without a fan.

Would love to see what a kill-a-watt has to say about a FEA with and without a fan. It uses very little power believe it or not... I have another one working in a cabin with no fan working only on solar power with batteries... I put a killawatt meter on it like I do on every appliance and I couldn't believe how little it used... I don't remember right now but it wasn't much.. I do remember it used less power than a modern new 5 CF freezer... When it cycles on it only runs for about a min and a half.. And it stays at 20f give or take constant on the top shelf...
