Sub Zero refridgerator power consumption high coolant or copmpressor??

Posted by Boboranntrottier on March 16, 2007, 9:23 am

When I recently measured teh power consumption of my 1998 vintage sub zero
550 refrigerator I found that it is using about 4 KWH/Day which is at least
50% higher than teh manufacturer claims.
It appears the refrigerator compressor is running most of the time.at a
setting of 5 the refrigerator maintains a 45degree temp
The condenser is not even warm so I'm thinking its either in need of a
recharge or a compressor
being recently unemployed I'd liek to get this resolved as innexpensively as
possible and would appreciate any suggestions on how to proceed
thanks in advance

Since you have the time right now, try cleaning both evaporators and
condensers (outside and inside) if you can get to the inner ones easily.
SubZero units are almost always dual systems, one for fresh food and one for
freezer. You should see two complete systems when you remove the access
panel. It is best to think of it as two seperate units.

I hope this is helpful.

When the compressor is running, the tube from the compressor to
the top of the condensor should be so hot that you don't want to
touch it.

If it's not, that sure sounds like low freon, to me. I think they
started to come out with 134A in 1993 (memory failure!!!) and so
it's probably the new refrigerant. In any case, it's not dificult
for a licensed appliance technician to juice up your refrigerator
with new refrigerant.
