Question about Sub-Zero 632 / S
Over a few days the drawers began warming up. First thought was to remove the kick plate and vacuum the fins. Found that they were totally covered in lint / dust. I vacuumed them and put the kick plate back. The compressor still works but the drawers are not cooling. I have turned the unit off, reset the cooling temperatures and still the same problem. Is there an "easy fix"? That is, before calling in an appliance repair person. Not sure if it may be the thermostat? Thanks
If your unit is new enough to have an on/off button on the keypad, then put it into diagnostic mode by pressing and holding the "colder" button, the pressing the on/off button at the same time. the display should change and it should read a temp like 67r or 67e. you can scroll back and forth through the 2 temp readings by pressing the colder key. If the fridge has been running, the temp of the one ending in "e" should be no more than 38. If it is, then you most likely are low on freon and will need to have the evaporater replaced. The part will be covered under the 12 year parts warranty, but the labor will only be covered for 5 years.(from date of install, not date of manufacture printed on the lable) If you want to go into it more, take the lower drawer out and remove the 6 screws holding the panel to the floor inside the fridge, then slide out the floor panel. Look at the coils in there, and if you see a ball of ice on the left hand side, you have a freon leak and the above repair is what youll need to to. if its older than 5 years, ecpect to pay about$500 to have it fixed...it's a mojor pain. If its less than a year out of the 5 year, call subzero...theyll probably take care of it for you anyways. Good Luck!
