I have National Refrigerator model NR-436 TES. It forms ICE. Rubber Gasket gone hard. I need asistance

I had the same problem and discovered that the water control valve was not shutting off completely between cycles. The water seeping through the valve was freezing in the water inlet tube. I replaced the water control valve for the icemaker and solved the problem.

I have had the same problem with ice forming. I found the problem is from the ice maker. The water fill tube delivers water to a plastic piece that acts like a funnel. The water goes through this plastic piece into the ice maker. Ice forms in the plastic funnel piece causing the water to overflow into the ice bin and freezer.

SOURCE: Ice keeps forming inside on the back panel of mysubzero model 550

If the ice is on the back panel especially a block of ice in the middle left part of your panel, then you have a sealed system problem. Check to make sure that your condensor coils above the refer are clean, and if it continues to have an ice block then you have to have a technician come out an do a major repair. This is not something you can do yourself, most subzeros have a 6 to 12 year sealed system warrantee that covers either all of the repair or just parts. This is an expensive repair if it is not warranteed, but when the refers cost 8000 to 10000 new it is usually well worth it. Most often it is the result of a slowly leaking evaporator, though most inexperienced technicians replace the compressor first, so make sure you use an experienced Sub-Zero technician. Good Luck, Appliance Specialits

SOURCE: water dripping from freezer onto top shelf of fridge with ice buildup back of freezer

the defroster isn't close enough to the drain to be effective. remove the back wall of the inside of the freezer, remove the excess ice. clear out the ice from the drain using hot water and a turkey baster. there is a kit from whirlpool that uses a piece of metal and a screw around the defrost rod, but I found out that a piece of 14 gauge solid core wire with the insulation stripped off works great too. stick the stripped wire into the drain, 2 to 3 inches, and wrap the rest around the defrost rod.
