1940s-early 50s Montgomery ward (frigidaire) refrigerator

[Vintagelectric]

Hi
I have what I think is an early 50s maybe late 40s Montgomery ward frigidaire refrigerator that I'm having trouble finding any info on using the model number. Im in the process of rewiring due to most of the original wiring is bare copper. I'm having trouble finding out what to replace the start capacitor a 192-232mfd cap, does it have to be exact or can it be off in value. I found a replacement but it's a 189-227mfd. I thought of just getting a 3n1 but I hear that can wear the compressor out sooner. I also want to replace the original Bakelite yt motor relay. It's been "asleep" for 25+ years but was told it was working when the power was shut off to it. I just figure that old starter cap will probably be dried up since most of the exterior wiring is. But hopefully I can persuade it to run again. I hear these rarely leak refrigerant since they're hermetically sealed. any info on this and advice on replacing the relay and starter cap would be greatly appreciated.

Thanks

Model: O5DOS970A

That new start cap should be fine-the value on these is not critical.Can the orig start relay be cleaned and freed up?This would be worth a try.Otherwise replacing it and the cap would be a good idea.Have a refrig tech check the refrigerant levels.

50s Montgomery ward (frigidaire) refrigerator not cooling

Thanks for the reply. I got the compressor to start up on all original parts except the wiring and power cord. Now I've got an even bigger problem it's not cooling. I let it run for about an hour and a half and the freezer section is just as warm as before it was plugged in and a faint hissing can be heard coming from the evaporator coils. I just want to know is it a giant paper weight or is there anything that can be done for it.
