Question about Sub-Zero 650 / O Bottom Freezer Refrigerator

1 Answer

SubZero 550 not cooling, ice film

Subzero 550, freezer drawer on bottom: Ice film on back wall of refrigerator (up to about seven inches above vegetable bins). Cold at bottom of fridge, warm near top. (Back wall cold to touch at bottom, not cold to touch at top.) Fridge door gaskets not warm, nor is the frame, except at the bottom above the freezer. Compressor, freon, fan? Which one? all or none of the above? It's possible that the fridge was left open (lots of kids, warm day)--any way that could be the culprit? Thanks for your expertise!

Subzero freezer not freezing

this subzero freezer compartment did not free, but stayed cool. The problem was that defrost limit switch went bad, so when it was going to defrost cycle heater never came on, so it builded up snow and ice on evaporator coils and air stopped circulate. I replaced that little thermostat, and melted down ice.

I have a Model 550 SubZero Refrigerator. I have ice build up on the lowere left rear interior wall just above the criper drawers. Can you advise on cause and fix?

Check your door and door gasket. Make sure it has a tight seal. The ice is from air and moisture getting in on the left side.
I hope this helps. Please leave feedback.
Thank you.

This is typically a problem with the sealed system (refrigerant leak). Usually a circular patch of ice or water driplets half way down on the back wall. The solution involves replacing the evaporator coil. Subzero will give partial warranty up to 12 years.Full warranty for 5.A subzero authorized company is recomended.

SubZero 550 Water keeps collecting at the bottom of the refrigerator, behind the vegetable bins. I see it leaking from the drain pipe and the handyman has tried to clamp the pipe, but not sure why so much...

your drain may be plugged... it will need to be clean and clear... it may freeze too it you have ice in it you will need to add a drain heater to keep it clear

Ice acculation under crisper drawers

No. There is, however, a drain hole in the back center that tends to get plugged. Remove the lower two drawers and see if it is plugged. It drains to a pan under the unitand behind the kickpanel

Subzero Model 550, freezer not working properly

Blow out the condenser with an air compressor. Make sure the evaporator coil is not frosted up, if so, the drawer may naot have been closed properly, or you may have a defrost problem, (timer, terminator, etc). Possible freon leak in the high side drain loop. Compressor may not be pumping efficiently, could have a bad condenser fan motor.
