Ice on walls on ideal model 55

On my ideal model 55 I had pulled the liner out and put new insulation in. I attached the copper lines back to the liner with aluminum tape. Everything seemed fined but I started getting ice on the walls of the bottom section. The top section with the rack runs about 39 to 40 degrees on average. Does anyone know what might be causing this?

            Thanks.

Hi Tommy,
Are you talking about ice on the inside liner or on the outside of the machine? Glen (moondawg) and possibly others have had more experience with these sliders than I have. On an upright machine (like a 39, 81, 110 etc.), you should have some neoprene washers separating the liner from the cabinet; otherwise, condensation will appear on the outside. Is it the original compressor or a new one? How were the refrigerant lines originally attached?

Thanks for your support Tom.
         Tommy.....there is a hollow tube soldered to the side of the inner liner, it houses the capillary tube of your thermosat. If that solder weld breaks, and the tube does not touch the liner...the compressor will run too long, not shut off, and ice up.
         Re-solder that pipe...or relocate cap tube

The icing is on the inside of the liner. The tube the thermostat cap tube goes in is soldier very well to the side of the liner. This is a new compressor deck I purchased from Eric. I went back with real r-12. What is the perfect air temperature inside the top section where the rack is? Would it be colder in the bottom section than the top section?

             Thanks for your help,
              Tommy

Could your R-12 be overcharged?

I am not extremely knowledgable of refrigeration systems, but could a larger compressor (ie. 1/5, 1/4, etc.) than was originally in the machine be a factor.

If the compressor was rated at a higher H.P. than the original, that could cause the problem. If it was overcharged, you would encounter a problem called "slugging" the compressor is way to full and doesn't ever get to temperature and will end up burning itself out if ran to long/often.

On the flip side, if the Eric you're refering to is Eric from Global Compressors, just give him call. On that same note, I highly doubt that Eric would substitute an improper compressor for the application or overcharge it, he's to much of a perfectionist! '>

Oh, I agree - Eric is a great guy, so definately give him a call and he will fix it if it is his work. Maybe Eric never saw the original or there was some miscommunication involved. I was just posing a question as to the reason ice is forming. As I said, I am by no means knowledgable about refrigeration systems.

What about a leak in the lid gasket? It the machine is getting moisture inside it will freeze up. My father had an Ideal 55 for a long time and it always had ice on the walls. Every fer months it would be a few inches thick and we would have to use a putty knife to get it off. It would always come off in one clump.

Tommy,

Did we send a new thermostat with the lower unit or are you using the original
one? The other thing is that your machine is a "static cool" unit meaning there is
no evapeoator fan on the coil itself, like an upright machine. You could have easily
overcharged the system causing a "flood back" or "coil over-saturation". This will also cause some frosting in the box. And finally,as mentioned above, it could simply be a bad or non-sealing rubber lid gasket.

Call me if you have any questions!
