Poly tube on the foam can - I have done that occasionally - one time tube came off and foam splattered everywhere including me. Luckily was wearing safety goggles *as I always do with foam and spray paint).
I have been following your videos for a while - I even repaired an old 1950's era GE refrigerator with your videos as a guide. Do you have a guide on how to build that start device you used when testing the compressor?
Thank you! Glad you were able to use my advice for repair help. As for the test cord, it is nothing more than a Supco RO81 device with a lamp cord and alligator clip leads to connect to the compressor.
Do know know what years GE used this style of compressor? I've been on the lookout for one to replace the compressor in my 50s GE wall-mount (locked up) but I'm not sure where to look. The fridge you sourced it from looked late 60s from what I could see.
I believe it was used until the mid 1960's but I am not 100% sure about that. They used a similar-appearing design in the 50's which failed quite a bit (probably what yours has) but the good ones were 60's.
