Yesterday I got the motor's rotor back from the shop where it was balanced. Interestingly, the rotor was not badly out of spec. The worst part from a balance standpoint was the pulley. After installing the newly balanced rotor, and replacing the pulley - the difference is night and day! Got a...

That is very interesting! These compressors have a very long life because of the low operating speed and lower pressure refrigerants used back in this day. It is not surprising that the 1933 model at the grocery store continued working until the mid 1970's. There was surely someone who took care...

Hope you folks are enjoying reading and watching this project come together. The previous posts were shared on the Monitor Top forum already and then shared here. This is today's status of the project. In spite of using new-old-stock discharge valves in the compressor rebuild, there was excess...

Got some good news today - the test run is underway! There are some concerns which will need to be addressed. First is the motor has a small vibration which is, in my opinion, too much. It resonates with the base and causes noise which will be heard when the unit is running. Temporarily, to...

Within minutes of startup, we have frost on the evaporator! The sight glass cleared up nicely. No dirty oil or other cloudy trash circulating. Thermal image of evaporator. The angle plays tricks on the camera. The whole thing is more or less equally cold. Colder than -10°F (-23°C) to be exact...

Got an update today! Yesterday I was able to get this project to the testing phase! Started out by studying an old motor from another similar-vintage system. This motor is 100% original and came from a museum collection at some point in the past. Of note is the protective sleeve over the...

I replaced the end of the left condenser, which had the defective flare. Then, I installed the sight glass on the receiver outlet valve; and the filter-drier under the frame. Those two parts got a custom-made copper line to join the two. The left coil has a new piece where it attaches to the...

Yesterday I put the compressor back on the base and reconnected the condensers. I replaced the end of the left condenser, which had the defective flare. Then, I installed the sight glass on the receiver outlet valve; and the filter-drier under the frame. Those two parts got a custom-made copper...

As for the Frigidaire system, I made quite a bit of progress in the past two days. The video ended up over an hour after editing, so I broke it down into two parts. This project has two somewhat-opposing requirements. It is to be as original as possible, but it also has to be very reliable...

Got a project to share! Thanks to fellow Monitor Top forum member Kevin Jones; I have been entrusted with repairs to this amazingly well-preserved Frigidaire cooling system. This is original to a home constructed in 1926 which is having some repairs done in celebration of turning 100 years old...

Thanks John! I'm glad you enjoyed it. A agree these compressors are built on a high volume highly automated production line. I expect there was very little human intervention, aside from certain quality check points along the way. They generally last a very long time, as you know. The one with...

Actually I do have a Kelvinator with a brine tank! It's a 1929 model if I am correct.

Should not give surprise failures, as long as you watch for any changes which may indicate it needs service. Just watch that the fans keep working and the compressor isn't running 24/7 and not cycling off. Very happy that you're enjoying my videos, too!

Hi and welcome to the forum! I sent you a private message just now. If you can't see it, feel free to reply here again.

That is possible! I have seen more than one of these with the relay bent upwards. They usually survive this if you catch it, but apparently won't go on forever like that. It also seems GE sized the overload protection a little on the large size; or possibly these require more current / heat to...
