Sub-zero refrigerator not getting cold - model 532
Hi, we have a side-by-side built in model 532 subzero and the freezer works fine but the refrigerator is not cold. We did have ice buildup in the refrig portion. I read the top/bottom refrig cure to use a blow dryer and shop vac, but where would this all be located on a side-by-side? Thanks!

check the fan that runs between the freezer and the fridge --check fan for ice blockage -debris-or damage / clean or clear blockage --if not running test wiring and connections as well as motor /repair or replace //also check fan damper is not frozen or blocked its flap that opens and closes for air to flow //----ur fridge side is cooled from the the freezer side the cold air is blown in from the freezer if fan or damper is not working correctly than fridge is usually warm and freezer is working properly
Did u check condenser on the top behind the grill? If it's clean, check unit for evaporator freon leaking. Light....Possibly bad bulbs behind that plastic light cover or light switch - one of them located on upper portion of door frame.
Unit has separate compressors and thermostat's. Clean the condenser, if it doesn't improve call for service, as there is a decent chance you will need sealed system work or defrost issue. If you need instructions on cleaning the condenser check subzero.com.also try advanceing the defrost timer as they mostly die in the defrost cycle. Behind the grille there will be a panel with a small hole in it with a screw above and below. Use a flat blde screw driver to turn the gray piece in th small hole clockwise a few clicks. If the freezer comes back on you will need to replace the defrost timer.
There are two door switches one for fan and the other for the lights. With the compressor running, there are two so yu need to make sure it is the refrigerator and not the freezer, open the door and press the right switch and listen for a fan. The left should be your light switch and the problem is generally in the switch, on rare occasions there is a failure of bi-metal safety switch part number 4200850. One very rare occasions you may have a wiring proble.If you go to www.subzero.com there is a showroom locator tab on the top right corner, click it and you will go to a locator page which will get you to your local parts didtributor.
First do the simple things like cleaning the condensor coils and turning the defrost timer a few times, also check the evaporator motor or just listen to the fan by opening the freezer door. Also check the light switch, make sure it turns the light off every time you close the door.
