Sub-Zero 700 Refrigerator Freezer Drawer-700 Sub-Zero Logo
Anonymous Posted on Dec 15, 2012

Sub Zero 700 suddenly stops after 12 years. Compresser is burning hot.

Apparently sudden failure, runs as normal, but temp is only 40 degrees. Condenser is kept clean. No apparent leaks. Door seals ok. 12 years old. The compressor is very hot to the touch. Should I repair or replace?

    After 8 hours at 40 degrees any ice blockage has long since melted, but the problem remains. The 700 is sealed tight with sheet metal with the only acces from the front, and there are no mice running around my diningroom. So I doubt there is mice damage. I unplugged the unit for about 2 hours and the compressor temp has cooled to 101 degrees. I am guessing it was a lot hotter before.

The compressor will normally be 100 to 110 degrees. I would suspect the thermostat or mouse damage in the freezer area. Also, if you keep it overstocked, to the point of poor air circulation, you could just have ice blockage. Put the frozen food in a styrofoam cooler or a good heavy corrugated box and give the unit a good full defrosting.

    David, I turned the Freezer off for 24 hours. Now it seems to work again. Temp is back to zero degrees. I suspect that Ice blockage was the culprit as you suggested. Thanks.

    There are portals between the freezer and the fridge. They are lined with styrofoam. Once they get ice in them, it's miserable trying to get it out. I use a hair dryer to speed things up. Luckily, I have an old bonnet style, with a hose.

Freezer stopped after power outage

If the sides are hot, look at the defrost timer. Sounds like it has stopped running with the defrost elements on. The compressor has a safety switch on it that opens either if the compressor gets too hot or if it pulls too much current when starting. If your power flickered a lot before coming back on, that triggered the safety switch. Now that it's running normally, I wouldn't worry. The defrost timer is your problem now.

Water is leaking out from the fridge floor onto the ground.

The drain pan in the back evaporates from the heat of the compressor. The freezer drain drains into this pan. If there is water under the bins it sounds like the drain is partially clogged and over flowing into the refrig section. But I need more info, like model , brand.

My freezer drawers are very warm All food defrosted smells horrible even after cleaning. Should I clean condensor, temp is not cooling?

It is likely the condenser fan is not functioning, or the condenser is dirty. You may need to open the compressor access panel to check. If you can hear the compressor running, and the condenser feels warm, the fan should be running. If it isn't, it probably needs to be replaced. Another symptom is the area around the doors feels warm.

Water on floor

The hose that goes into the drip pan to defrost the refer is plugged with stuff.
take the back off and see the hose connection.A coat hanger works well.Usually a 1/4" hose.
Also see where the bottom of the freezer drains into the drip pan.That may be plugged,also.
The temp may be set too low and the condenser is frozen up,leaking water into the floor.Just ice stuck to the condenser.
Possible that the condenser FAN stopped turning. That will ice up and melt at random:
see/hear that the fan is working.
If stuff gets into the fan,it will ice up,melt and make a mess on the floor.

I have an older commercial upright Hobart freezer. The freezer seems to operate fine, cycling but always returning the compartment to zero degrees, until all of a sudden the temperature went up, well...

In most cases, an evap that freezes up is either an air flow problem or no defrost cycle. Older Hobarts have mechanical defrost time clocks. It could be locked up i.e., not running so no defrost cycle.
It could be coming out of defrost too early because the sensor that monitors the evap temp is not working properly.
The door could not be closing. If left cracked open, it will freeze up every time as unit never hits temp., keeps unit running. Warm air is seeping in and the moisture freezes on evap.
Lastly, the defrost heater(s) may not be working. Burned out, shorted, broken wire, etc.

Good luck and hope this helps.
