Question about Sub-Zero 690 Side by Side Refrigerator

1 Answer

Older subzero side by side not cooling

ITs about 16 year old. Freezer is fine. We've always been able to keep the fridge at 4 and it was cold. Yesterday, i had to move it to around 6 and it got plenty cold, so I moved it back to 5. Noticibly warmer.

The door gasket is original, and certainly not as magnetic as it used to be, but torn. Could it be the problem?

I replace the blower at the top several months ago, and when I push the switch at the top of the refrigerator, it goes on.

Freezer is fine.

At sixteen years old it is almost through its life span. A change in ambient temperatures will change internal system pressures. Make sure the condenser is cleaned well. Use a vacuum cleaner to clean off the condenser, then blow it out with compressed air. Even though a condenser looks clean on its surface fins there may be dust down in between the fins.

Subzero 532 refrig fan(& compressor) doesn't shut off

the higher the number on a fridge the warmer it is so setting it to 1 is close to 0C
when working on a fridge or freezer always turn it off at the wall
if the fridge is keep cold but not cold enough set it back to say 3
if the compressor is running and the back fins / wall is hot then the fridge is working
use a piece of paper between the door seal and the fridge edge to ensure that it is sticking to the fridge and sealing off properly

Would like to put older side by side refrigerator in our garage. I was told in the winter, when it gets cold the freezer side will not keep foods frozen. I had an older top freezer refrigerator in the...

It could be a problem depending on how cold your garage gets in the winter. Most refrigerators depend on the compressor turning on to cool the freezer section and that cold air is used to cool the refrigerator section. If your the temperature in your garage gets in the 30-40 degree range in the winter. The compressor may not turn on sufficiently since the refrigerator is typically around the 35-40 degree range. This will cause the freezer to warm up to the fridge temperature and your freezer items will defrost.

Fridge not getting cold

if the fridge is running, but not cooling, only two things- the coolant has leaked out some where, or compressor is worn out. it could be repaired, but if its an old fridge it may not be worth it .

Freezer is cold but not keeping icecream frozen.

If, the fresh food section is 34- 38 degrees, then the freezer should be cold enough to keep ice cream solid. All of the cooling capability comes from the freezer section. I, personally, would not waste time or money on a ten year old box. Ten years ago it cost $1000, so, the outlay is $100 per year. Dump the old refrigerator and get a new one.

Fridge side not cooling, Freezer side is....

(After trying FixYa and paying for the premium service -- during which error codes were not even discussed) I called a service tech. Turns out it was the fan above the fridge side (which explains why the freezer was still working fine) that was "humming" but not always spinning. A quck swap of the fan and we were back in business.

FYI -- The SubZero tech said it was very uncommon for the fans to go bad.
