If you look at the other side of the compressor it should have the low side port on it. That side houses the electrical connection. Hi ckfan. I did see that on the other side and kinda figured that’s what it was. I also noticed the one on the condenser line. I’m learning as I go .. haha. My brains in overload lol. Where the wire goes into the side of the compressor, it looks like it goes into a cap or cover ? I can’t see any terminals where the actual wires connect ,To check for leaks. If it’s a cover how do I remove it ? Normally I’d mess with it till I figured it out, but in this case I’m being more caution. If I ever get it to cool properly, I plan on changing the cord to a grounded three wire. So leaking or not I’ll have to get in there at some point. Thanks AJ.

Nice fridge - I've never seen that particular model in person, but the evaporator is kind of neat, in that it is clearly an evolution of the CK-style evaporator of a little more than a decade earlier, but I think that having a miscible oil+refrigerant mixture is a different ball game. Look at this thread for hints at the wiring, particularly the posts about the wiring being a bit of a pain where it enters the compressor. That little cap is apparently troublesome. The freezers have a similar style compressor. There doesn't seem to be a way of non-destructively removing it.

Honestly those caps are impossible to get off. Since these compressors have metal glass terminals I wouldn’t worry about leaks there. I’ve never heard of one leaking. They are sealed up like a light bulb. Other brands used rubber seals and those can go bad obviously. I had to take an angle grinder to carefully cut the cap out so I could replace the wiring in my freezer. Oh, and the service ports will have a shrunken plastic cap over them. You will have to cut those off with a knife before you can get to them. If the wire going to the compressor isn’t in bad shape or crunchy I would leave it alone.

It definitely didn’t look like it would be easy to remove. The wire really doesn’t look bad and is still soft and flexible. Rewiring is something that I like to do with older alliances. But in this case, I’ll leave well enough alone. Thanks AJ.

Yes those caps are on there. The 48 my son uses I had to cut the cap with a sharp chisel to finally get it off. Glued it back after the rewire with silicone.

I haven’t had much luck getting any one to come and look at this fridge. I’m thinking most likely I’ll have to tackle this my self. I’ve been doing some research. I’m guessing I’ll need a manifold gage and possibly a vacuum pump. Could I just get a set of gages and some R12. ( I’ve seen it on eBay ). And try adding or at least checking to see if it low on Freon ? And then go from there. I’m not sure where I wanna start on this.

I have two complete cooling systems out of spacemakers, one was a 51 and the other I think was late 40's. If you want to drive to central Illinois I could part with one. Of course they would still need a rewire.

I just need to put together the right shopping list for everything I’ll need.

Possible progress maybe ? I was looking at things last night and decided to fire it up just to see if any thing changed . They kinda did. Now almost half of the right side if the evaporator gets frosted now. Before it was only about a 1/4 frosted. Wile I was looking over things I noticed That the front feet were adjusted all the way up. So I had to tilt it backwards to adjust them. Then I tilted it forwards some wile looking over the compressor and condenser lines. This is making me think that there’s probably a clogged line . If it’s a clogged line are there any other tricks to help move the clog along ? Thanks AJ.

Assuming the compressor isn't sounding bad or getting excessively hot, you might want to give it more run time and see if additional improvement happens. If the restriction is due to oil sludge which migrated into the capillary tube, most likely the only non-invasive way to eliminate it is by running the unit.
One thought; you could apply heat to the capillary tube with a heat gun (with fridge powered off) and then turn it on after the tube is nice and hot along its length.

Oh man! That’s exciting! I hope it starts behaving.

Hi turbo. The compressor still sounds just as it did in the video I posted a few days ago. It’s does get hot to the touch but not burning hot after it’s in for an hour. I did let let it run for 2 hours last night. I put a small fan under neath blowing on the compressor. I figured since it had fins on it. (Kinda like a big heat sink). That it would help keep the compressor from over heating. And it did keep it pretty cool. I don’t have a heat gun, but I’ll try running the hair dryer on it for a wile and see if it helps. Thanks for the advice and good luck with that 193Os fridge you’re working on. I’ve been following your posts and vids. That’s really cool! Can’t wait to see it up and running ! AJ

I've had some of the Frigidaire Meter-Miser rotary compressors take a long time to start cooling after an extended shutdown. I would let it run and see what happens. Obviously there is refrigerant circulating or it wouldn't cool at all.
If you don't see improvement, then maybe try the heat approach. If you follow the lines on your fridge condenser, it should end in a "bulb" sort of affair. I have always thought those had a screen in them or some other filter. This is where the end of the capillary tube is brazed into position. This would be the most likely place for a blockage that I could think of. If there was sediment trapped in this area, it could have become trapped on the end of the capillary tube while the fridge was on its side. You might want to let the fridge sit overnight so that all pressures equalize; then apply as much heat as you can, to that area.
Glad you're enjoying the 31 Frigidaire thread! It's one of the most unique projects I've done, that's for sure.
Sincerely, David
