  Hello, enthusiasts! I’m a first time monitor top owner and I’ve had mine for about seven months problem free. Before I go any further I’ll say that I’ve made good use of the search function before posting - the last thing I want to do is duplicate anything! I’ve noticed the top of the dome feels always slightly warm but nothing out of the ordinary or other than to be expected. However tonight I noticed it feels hot to the touch, and I want to see if I need to be investigating anything. For the record, the temp setting is around 7 or 8 and it’s staying around 40 degrees inside. There’s still ice in the trays and the ice inside on the cooling unit is hard and solid. It’s also our only fridge, so turning it off overnight isn’t something I’ve considered, on account of spoilage. I have *some* technical skill but anything electric often things evades me. I appreciate any input you might have - I just want the best for my beloved fridge! |

Oh yes, forgot to mention - it’s a 1934 CA.

Bless you for searching for information. It sounds like it’s not cooling well if you’re thermostat is set nearly to the max. How does the frost line look in the headers? How long is it running? How long is it off.
It may need the NCGs purged and may have a worn float seat. You’re going to have to come up with alternative refrigeration to make repairs.

Hi, Travis - thanks for responding to the post. It seems to be doing a little better today - I've got the temperature setting at 6 and it's holding at 40 degrees (the thermometer is on the bottom shelf, so almost two feet away from the cooling unit. I took a picture of the two small metal lines that lead to the cooling unit (condenser?), and they don't have any ice on them. If I can figure out how to upload the photos to this post I will. The ice itself around the condenser it solid and doesn't "chip" easily by hand, and the ice in the trays still looks good.

The headers look good with plenty of ice on them, business as usual. The two small leads however don't have ice on them. At the moment the machine is doing its thing at temp setting 6 - it's off for the moment. I should have noted the time when it went off!

The dome on a CA will tend to run warm since unlike most other compressors, the dome is on the high side. That is to say, it's full of compressed refrigerant. And compressing refrigerant makes it warm. Most compressors have their dome on the low, or suction side which means cold refrigerant is being sucked into the dome. What you should find is the condenser also runs warm. If it doesn't and the dome is hot, that would indicate NCG's. But, I would expect the float valve to stop working before that happens.
On a hot day a CA dome can seem alarmingly hot...but as the manual says, as long as it's not "hotter than the hand can stand" it should be OK.
I'd recommend a plug in power meter to see what's really going on, and to take note of its run and off times.
The tubes to and from the evaporator are not usually frosted.

Also have you checked the heater?
If it’s not working it could create problems !
Look in the ca section how to check, you we’ll need an ohm meter to check to see if it’s working.
We can walk you through it if you have questions.,
