It is likely the condenser fan is not functioning. 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.

sounds like the mullion heater (drain tube heater is open). take back off (after removing all shelves, including the glass tray (remove 4 screws). Pull back out, careful not to pull wires off T'stat. Run the new wires on heater behind evaperator, placing heater down in drain hole. Good Luck

There are three parts to all defrost systems.
1. Defrost Heater2. Defrost Timer3. Defrost Thermostat
Without a model number I could not look up a diagram or part numbers. I very seldom see a bad heating element. Most common is a bad defrost timer, second most common is the defrost thermostat.

The condenser is the 'radiator' located under the unit near the compressor. If it's clogged it will cause this. Make sure, also, that the fan at the condenser is operating.

If you've not yet cleaned the condenser, do so with a vacuum both sucking, and then blowing, to clean it well. BE READY FOR A DUSTY MESS!!

Check the relay on the freezer compressor. It may be shot.

This is normal. Freezers have a vent port to let high moisture out. When you open the door moisture laden air enters. When the door is closed the hot air from outside expands and leaves through the vent port. This creates a vacuum in the freezer that lasts a few minutes. No problem

Diagrams here : http://www.searspartsdirect.com/partsdirect/part-model/Sub-zero-Parts/Refrigerator-Parts/Model-2811/3054/0161000?searchedModel=2811&blt=05

These are the best I can Do with the Diagrams but I can explane what is going on, and possible soloutions.

Your defrost drain is mostlikeley frozen. This is located on the right hand side, just inside the metal cover. When you remove the meteal cover (((evaperator cover or water pan))) you will see the hole on the right.

Since this is cloged then the water stays in the cover or pan and freezes after the defost cycle.

after you remove the cover you will see the evaperator (( aluminum tubing with fins))) and the heater ((( Black Rod )))

When your machine gose into defrost about every 8 hrs, this heater melts the ice off the evaperator((( Hence Frost Free ))) and the water goest into the (((( evaperator cover or pan ))) and flows to the defrost drain hole to a pan under the machine.

They make a after market heater for the drain... it is a pain to install.

First I would try to defrost the drain by poring war water down it and verifying it goes into the pan at the bottome of the machine.

When your done you will need to silicone around the (((cover / pan))) where it covers the defrost drain hole.

Good Luck
