I found a replacement switch for extremely low price. I need to recharge the refrigerant what do I use?

Frigidaires from this time period used R114. I know David Allen has found a substitute for it since you can’t easily get 114 anymore. David, thoughts?
Also, I believe I was chatting with you via the Facebook antique fridge group.

Also, I believe I was chatting with you via the Facebook antique fridge group. Yes, David is the man to advise you on this. I do know that David has used r152a in some retrofits, but initial examination reveals that is not a "perfect" replacement for r114. I am not familiar with the box that you have, so I can not advise. It is quite possible that r152a will work. It works pretty darn good for a SO2 replacement in my 32 Kelvinator, but it has an AXV.
David has not been on for a couple of days, but give it a couple of more. Maybe he is out of town.

Have you found and repaired the leak? This will need to be done before the system is pulled down into a vacuum and recharged. Adding or replacing the existing dryer, if originally equipped, would be a good idea too. Look at the bottom of the compressor, where the wires attach, do you see oil? If so the terminal seals are bad. They were made of rubber and if handled roughly tend to start leaking. Refrigerant doesn't wear out, it leaks out. If the leak is not repaired a recharge will only offer a temporary fix. Possibly a very temporary fix.

Just to note. R152a will not work in this machine. It is too high of pressure and will stall the machine.

R124 MAY work (probably), but will require dumping the mineral oil and replacing with AB.

Thanks. I have been on a work assignment for quite a while and not spending much time online. R124 is the original replacement for R114 and can be used with the original oil. R1234ZE also works, but it has somewhat higher pressure than R114 and therefore will reduce the maximum ambient temp in which you can safely run the system. If you aren't running it in the hot southern regions, in an un-airconditioned space this shouldn't be a problem. |
