You sir are a God amongst men. Thank you doesn't describe my relief on how simple a job you show this to be. Thank you for the simplicity and straight forward info. Please make more videos.
Also, on the 550 I’m working on, the instructions are saying the larger bulb is on the right side and the single one is on the left, but i see people online are doing it different ways. I just did a replacement for a customer and now the fridge section either freezes or stays in the 60s. Maybe faulty thermostat? Very weird behavior. I reordered the new thermostat and will try again. Also installed new start relay and overload so thats not the issue.
@@paulk7895 if your tstat has two bulbs, then the fat one goes below the evap coil on a 45 degree angle and the thin one slides through the fins of the evap, you should have gotten instructions if you bought a subzero part. Otherwise there should be some pics on my website under tech help. The freezer tstat capillary should not be touching the evaporator tubing.
Great Video. Our 550 (from 1990 (is fluctuating between about 32-42 degrees with a separate thermometer in the fridge. Fan above the unit seems to be on all the time. Freezer is working great. Is a new thermostat the right answer or do you think something else?
In my limited experience, these particular models will fluctuate temperature more than a typical newer model. They do not have defrost elements, so it relies strictly on ambient/passive defrost. Id take a look at your door gaskets, excess warm air will cause frost to form faster and the cap tube on the evaporator will turn cooling off earlier than it should to avoid over frost.

Thanks for the video! Quick question is it a problem that freezer capillary line touches the fridge line behind the panel?
No
Are you talking about the capillary tube from the thermostat ?
Yes

I couldn’t say without knowing the sealed system pressures.

Hello there, do you have P/N for the freezer side of the 550?
Go to my website aaronsrefrigeration.com and look up parts.
