Customer Question

Sub Zero 611, 7 years old. Had the flashing Vacuum Condensor light, would go away after power cycle...for a little while. Took the top off and vaccumed the fins but after doing so, the freezer is working much better but the fridge won't drop under 62. Help

is the condenser fan running in the top?

Customer: replied 7 years ago.

Hi Bryan,


It's a 611 fridge on top, built in. I have removed the white panel behind the top of the unit and see that the fans are running and both of the black (condensers/compressors???) are running. I removed power to them then plugged them back in to ensure that they were kicking on. All of this started immediately after I vacuumed the radiator fins on the right side of the upper unit. Freezer and Ice Maker started working much better but fridge hasn't gone under 62! I can see no signs of freezing of condensation in the rear of the freezer either.

ok . are the lights going out when you close the door?
Customer: replied 7 years ago.
Lights and internal fan switches are working fine. Tested that too. I was an electrical tech for many years so most of the basics are covered.

ok, this may be a freon issue then, unfortunately you will need a EPA certified tech to check that though, the sub zeros are famous for that, wish it was a simple fix, sorry, thanks Bryan

If it's a refrigerant issue, do you have any idea as to why this would happen immediately after vacuuming the radiator fins?
Expert:  Bryan replied 7 years ago.
not really, unless you damaged a coil, or fin. don't think it has anything to do with it though, just coincidence.
