Question about Sub-Zero 650 / O Bottom Freezer Refrigerator

1 Answer

Subzero Model 550, freezer not working properly

The freezer of our subzero 550 is only cooling to about 30 degrees F. We think this model is about 20 yrs old, but until recently, it worked pretty well.

    After vacuuming out the condenser area, it seems to be working fine. It had been neglected and was pretty dusty. Thanks.

Blow out the condenser with an air compressor. Make sure the evaporator coil is not frosted up, if so, the drawer may naot have been closed properly, or you may have a defrost problem, (timer, terminator, etc). Possible freon leak in the high side drain loop. Compressor may not be pumping efficiently, could have a bad condenser fan motor.

My Subzero Condenser fan runs constantly - but coils are clean


If it is similar to mine at home (Model 550) the condensor fan is designed to run continuously, even when both the freezer and refrigerator are shut off. There is no control or switch in the fan circuit, so it just runs whenever the fridge is plugged in to the wall. It uses about 56 watts.

Subzero 611 Refrigerator not cooling, freezer fine


It sounds like a defective ref section evaporator. This is common, due to poor quality metal used in fabrication. If you call subzero, they will more than likely fix it as they are aware of this issue. It probably wont cost you anything if you get them involved.
