Question about Sub-Zero 642
Chartigan - had this problem with my 1998 642 about 5 years ago, and had to have the condenser coils replaced twice- because the refrigerant was leaking. warning signs are: temp is more than 37 degrees [ get a fridge thermometer to monitor], food seemed to spoil quickly, and frequent notices from the display bar to clean condenser . after cleaning it 3 times in a month, when i called the service center they said that warning actually means"call service center" - arrrggghh the manual sure doesnt say that! anyhow - just something to consider, and hope your problem is not this serious.

Clean your condensor. Check for condensation or frost on back wall that may indicate a refrigerant leak. If cleaning the condensor doesn't work call for service. Instructions for cleaning can be found in your manual or subzero.com.

The first thing you must know is that your refrigerator should be
set at 37-38 degrees. Anything at 40 or higher and you are risking
food born illness (food poisoning) or spoiling your food. Place your
magnetic thermometer in the refrigerator.
Set your dial on your refrigerator to the second lowest setting. (If
your refrigerator is already equipped with a digital thermostat,
simply set it for 37 or 38 degrees and do not move on to the next
After 2 hours, check your thermometer reading. If your reading is 38
degrees, there is no need to go higher and you are ready to put your
groceries in. Be sure not to open and close your refrigerator during
these two hours or your temperature reading will be incorrect.
4. If your reading is higher than 38 degrees, move your dial up to the next coldest setting and repeat the steps every two hours until you reach the correct temperature for your refrigerator.
Once you have reached the correct refrigeration temperature for your
refrigerator, place the magnetic thermometer in the refrigerator
permanently and watch for changes.
Typically, your refrigerator temperature will need to be adjusted with the seasons, a higher setting in the summer and a lower setting in the winter.
