Question about Sub-Zero 30.1 cu. ft. Cabinet Depth Side-by-Side Refrigerator 632 / F
My 10 year old Sub-Zero 511 has a very slow freon leak in the refrigerator side. About 3 years ago the service tech topped if off for $200, and suggested finding and repairing the leak could be very expensive. Since it's an R134a model, I figured I could do the occasional top off myself. About every 6 mos. I check the low side pressure and add a little freon. Takes about 10 minutes and solves the problem. When the tech did the job, he said "I like to fill them to 5 or 10 psi". I've been using 7 psi, which seems to work fine, but would like to know what the correct low side pressure should be, both for the fridge and the freezer.

Don't let the EPA know about you adding Freon to your Sub-zero.. you can get yourself into trouble... add freon to a system that leak is a big no no... you need to repair the leak... most Likely the Leak is @ the Evaporator... Sub-Zero give you a 12 year Warranty on Parts... the Evaporator is cover.. so I would Fix the Leak, stop adding Freon. .

Paul, we have the same problem with a built-in Kitchenaid and the price of replacing the fridge is out of sight for us. Where did you get the equipment to check the freon and replace it?
