Sub Zero 642 - Gasket on the Door is really HOT

Is it normal that the gasket along the opening side of the door, nearly the entire highth of the door is always hot? Seems wrong for the inside of a refrigerator to have a part that is producing HEAT.

Re: Sub Zero 642 - Gasket on the Door is really HOT

That is normal and is designed that way to keep moisture from forming water drops on the door seals. The "old days" used electric heaters but most now use the heat from the compressor liquid. If it's really hot you may have dust all over the condensor coils and should be cleaned to reduce the compressors heat output. Other than that, it's normal operations!

It is your evaporator fan. When the door opens power is cut to the fan motor.

I have ice forming on back wall above top drawer in refrigerator. Belive seal may need to be replaced. Any other suggestions?

The gasket would be the last thing I would suspect. Is the ice a ball to the left side or is it all the way across? Could be a sealed system issue or a bad thermistor. I would recomend calling a factory authorized servicer for proper diagnosis before putting the money into a gasket. Besides look at the gasket all the wat around for any damage and make sure the door is closeing properly. Isee units with torn gaskets all the time and it doesn't cause ice build up in th refrigerator side.

remove the crisper drawers and you will see a drain trough and a drain line . One or both is most likely blocked. If you pull the drain line off the trough usually you can clear it with a turkey baster filled with hot water

I have a 642/0 side by side sub zero. Although

Has the ambient temp around the unit been going up? Depending on what refrigerant you have here the pressure temp relationship will change in the system, also when you add foodstuff, and again when you open the door.

Cannot reopen Sub-Zero 642 freezer door for 50 seconds

Yes, this is normal.  My 642 does the same thing. It seals to be more efficient while trying to cool back down after it has lost heat while open.

Door gasket gap

Hi, Try rolling up a piece of paper towel and place it behind the door gasket to stretch it. It might take a few days to stretch.
I hope this helps.
Please let me know if I can assist you further.

Refrig lights go on and off intermittently when opening and closing refrig door

check door light switch with ohmmeter. Check for melted insulation near light "terminator". Look for wiring diagram in ziplock behind compressor grille. Second switch at door turns compressor off when door opened. I had these problems with a 695 which I would assume is probably similar in design.
