Might be a bad compressor. I've seen them burnt out, after the condensor
gets clogged with dust, and they can't release the heat. Another possibility
is low on freon. I've seen that, also.

The one time I replaced a compressor on a sub Zero, it was about $350, and I
used an aftermarket compressor. Worked fine, she hasn't called back. I've
also seen low on freon, th at happens, too. As the other poster wrote, some
units use two compressors.

Do good work.

Hi

I recently purchased a house that has a great built in Sub-Zero 550,
Model M697077. The tag says APR88, I'm assuming that's the date it was
built.

Things worked well until this week when the freezer just stopped
cooling. I dusted everything off inside the top part, making sure that
the fans were running ok and that their wasnt excess dust inside. I
hear the compressor for the freezer running, but the coils in the
freezer don't get cold. I don't hear any leaks/hissing. The fan runs
in the freezer when the door is closed or you push on the buttons that
active the fan in there. Inside the fridge there are two controls.
The refrigerator one is lit up (blue), but the freezer one is dark with
no light, even though the fans run and I can hear the compressor turn on
and off when I turn the dial off/on. Like I said, the refrigerator part
runs fine, it's just the freezer that has the problem.

I have only a basic understanding of refrigerators. Despite the fact
that I hear the compressor running, does the fact that it is not
cooling mean the compressor is bad? Or would it stop running all
together?

I realize that this unit is old, but it is a nice built in with
matching wood, so if the cost is not prohibitive I would like to keep
it running. Could anyone give me some suggestions, maybe someone with
a good understanding of Sub Zeros specifically? Are there things I
should look for first before calling the repairman? Does the lack of a
blue light on the control mean anything at all? Should I skip the
repairman because it would be too much, and just get a new fridge?
Basically, from this superficial info I have given, any thoughts on
what this repair will cost?

Thanks for any help you guys can offer. If you need more info please
let me know and I'll post.
