I’ve reviewed another thread that bears resemblance to my issue here: http://applianceguru.com/view_topic.php?id=14456&forum_id=1.  Posting a new thread per request in that thread.

I have a Sub Zero 690/F which if failing to stay cold on the fridge side and reports the "vacuum condenser" message.

I followed the guidance in that thread... I put a dollar bill on the fins and it holds just fine... but I went ahead and did some compressed air work anyway and got some more gunk (but not a lot more - not as much as I would expect if that were the problem).  I also wiped down the door seal to assure a tight seal throughout.  My front grill is not hot as described in that tread (seems normal).  I believe my fan is running at all times (not certain of this however).  The freezer/ice maker is fine (holds at -2).

The extra cleaning has not resolved the issue.  The only other thing that seems worth mentioning is that the fan *seems* like it is on overdrive.  When I take the front grill of its like a wind tunnel (and it seems marginally louder than in the past).  It seems like the fan is trying to do its job...

I got the following reply from AccApp in the other thread:

AccApp wrote: If the condenser has good airflow, the freezer is fine and no palpable hot spots around the frame there is probably a sealed system problem, Take off the back inside ref compartment panel and get a good look at the evaporator.
OK I found another fixitnow.com article which helped me along in understanding what you are asking... so I got the back panel off an indeed the evaporator looks a heck of a lot like the one pictured in that article - the below photo is one I just took of what I am seeing...

To quote that article: "If the coil is wet and clammy or if you see just a patch of frost on one corner, like this, then, ding-ding-ding, you got yo’self a gen-u-wine sealed system problem. Could be a bad compressor or a leak somewhere in the tubing that circulates the freon around the refrigerator. Either way, it’s trouble in doggie land. Sealed system work is expensive and, unless you paid so mucho dinero for the box that you’re married to it, you’re probably better off just buying a new refrigerator."

So I presume you'd adivse its time for a new fridge...?

Its definitely over 5 and under 12 years.

So its worth the $75 to have someone come take a look and diagnose the problem?

may need to be an authorised Subzero repairman, but yes, he'd be able to tell you the estimated cost, and what's covered and what's not...

you should take a peek at the Freezer Evaporator Coil also...

 98% chance,  Leak is in the evaporator,  3 hours and a new evap. with the repair of $525.00.......  Repair or replace?  That is the question........

 hi Kevinshi,

  Yes, for most equipment it depends on how much you like it, what your needs are and if this size and type of unit is what you want and need. You have to consider it's value to decide if you want to put money into repairing it. Suppose the repairman should dig up a couple more issues with it. The total repair cost could be a few hundred more bucks than Certified tech's estimate. What he's stated is really the base repair price because he's only referring to fixing that one issue you told us about and he hasn't looked at your refrigerator. What does the rest of the fridge's condition look like? Are the door gaskets in good shape? Are the shelves, drawers and inner doors in good shape? Do the fans seem like they have a lot of life left to them? Does anything else on it look like it might be worn out? You've got to give it an overall evaluation when you're considering replacement. On the other hand to replace a 48" side by side 18 cu. ft. framed refrigerator it could cost thousands.

  I would always go by the 1/2 Theory. If the total repair cost exceeds 1/2 the cost of a new one, you are better off to buy a new one. This is how I used to apply replacing equipment to my customers. A lot depends on your fridge being a framed one too because it's built into your kitchen's decor. So you would have to consider the size and the retrofitting of a replacement. All this considered, unless repairing it is going to cost a whole lot more, I'd say your's is definitely worth repairing.

 Bob
