Sub-Zero Refrigerators - Recent Questions, Troubleshooting & Support


How soon did you start it up after you moved it & put it in its place?
If you plugged it in to soon after moving. Oil may have still been up in the wrong place of the compressor. Unplug it for about an hour. Then plug it back in. By plugging it in to early after moving you could have burnt up the compressor. This happens often.

I fixed my leaking problem by pulling out the vegetable drawer and checking the condensation drain hose. Sure enough, it was clogged and the condensation had nowhere to go but move out toward the front of the fridge, down the left side and onto the floor. Once that drain hose was cleared (with a bendable straw), no more leak!

Hi,
With refrigeration pressures that will vary greatly with the temperature.
When downn to proper cool temperatures the low will be around 10-15 and the high side 150 or so

Fans working and air flowing thru the cooling coils?
The inside fan warms the evaporator, or cooling coil. If this coil does not go thru a defrost cycle or if there is ice build up to the point no air gets across it, that could be the scenario.Then it would need defrosting, or inspection to make sure there is free air flow both inside and outside the fridge, including the defrost timer if present. If all this checks out ok, then the refrigeration circuit is to be looked at by a technician.

This "problem" may not be a problem at all. When you open the door of a cold space you admit warm air. The colder the space is before you open the door the more quickly the warm air you admitted by opening the door shrinks (contracts) as it meets the cold surfaces. This effect causes a short term vacuum in the space. The vacuum prevents the door opening until the internal and external pressures equalize again. This can take several seconds. There is a drain for draining defrost water from the compartment that has a water "trap" in it which is intended to minimize the effect. In some models a gurgling sound can be heard when door is closed as the vacuum tries to **** the water trap back into the compartment.

If you haven't noticed this happening in the past there can be several reasons.
  1. Possibly you just never noticed the effect before.
  2. If your refrigerator has less stored in it than usual the air exchange when you open the door can be larger than normal and the volume of warm air admitted may take longer to "shrink".
  3. The thermostat for the compartment has been turned down without your knowledge or has failed making the compartment colder than usual.Take temperatures. Refrigerators should be 36-42 degrees while freezers should normally be close to zero.
  4. The drain for that compartment is clogged and needs to be cleared. A turkey baster with hot water can usually clear the drain.
Except for a faulty control and the clogged drain the other issues are no "problem" and merely a function of the "tightness" of the insulation of the refrigerator

If the water connection is beneath the floor, the slack in the water supply line allows the refrigerator to be pulled out for service without breaking the connection.
