The usual careless top replacement; high side tube gets pinched at the evaporator, float valve rises when the compressor gets turned on and out comes the refrigerant - in my case a face full of MF.

Yep, all too usual.  In this case, I "carefully" tried to move the tube to see if it was loose, and it didn't seem to be. But, it obviously leaks.
I just don't get it, why people turn the top around backwards on these so many times.

Ugh, that’s terrible. I’m glad you had a positive attitude about it though. I knew what had happened when you said oh no all of a sudden. I bet improper placement has killed more of these than anything else. Travis just bought a CA in similarly rough shape and it had this exact same issue. It smelt much better though!

I hope he's able to get his fixed. I hope to get a chance to assist Travis with some soldering sometime, as well - since this is a repeating theme! |

Sorry to hear that it’s leaking but it’s in good hands!

Thanks. I was expecting to have to do some work on this one, seeing how it looked. The patient is very sick: .JPG)
The damaged solder connection. Seems they all get broken here. .JPG)
You can see the separated solder bond at the right side of the solder area. .JPG)
All cleaned up and ready to go back together. .JPG)
And it's done! .JPG)
Evacuating for leak-check! .JPG)
While I was working on it, I rewired it. The original wiring was horrendous. .JPG)
All better now! New MTW wire with heat shrink sleeving to make a harness. It's twisted for flexibility. .JPG)
So, here's new video! I plan to remove yesterday's video since it was too short. I started this video with the same footage, so if you watched that one yesterday, skip to 5 minute mark!
So, that gets the damaged refrigeration system up to snuff. Next I need to locate a control. I believe the bellows is good in this one, but the mode selector knob is missing. I took the control apart and the works of it look to be in like-new condition. The mode knob retaining clip is still there, as is a piece of the knob. If someone has a control with a bad bellows, I would buy it for the knob....
Sincerely, David

I have a control with the bellows.

I have a control with the bellows. Hi Travis. I'm assuming you meant with bad bellows (since mine has a good bellows and only missing a knob)?

Yep I think I remember seeing a few of those at your place.... Seems eBay sellers clipped off the bellows tube as if it was an electrical cable! |

Question for you when you put the two ends back together did you use a coupling or just end to end ? Could not be sure buy the pictures .

Sorry about the unclear pictures! I used a coupler. The tubing was too heavy-walled to make a swaged joint (where one end slides over the other before soldering). I just put a 1/4" copper coupling over the cut ends and then used sil-phos on it. Those couplers are available at HVAC suppliers for a few cents.

Can't believe that's another one you've brought back to life! Is anyone keeping count? Love your work David, and thanks for another great video too.

As for bringing them back to life - the GE Scotch Yoke compressors are very hard to kill. Just give them what they need (refrigerant, voltage etc.) and they just plain work.
