Question about Sub-Zero Bottom Freezer Refrigerator
We get a little pocket of ice forming inside our Sub Zero refrigerator on the left side of the middle part of the frig. It only seems to happen during the summer months. Doesn't show up at all during winter. Any ideas? Thanks

I had the same problem with my 550...several times the tech came out and used a steam machine to blow out the drain...which didn't solve the problem. Finally, they ordered a refrigerator drain heater from sub-zero (part#4201290) and this finally fixed the problem. Hope this helps...I'm not a tech, just a customer. K

The leak in the system can be located by a number of methods. First I would look for a slight sign of oil at the point of the leak. 10% of the compressor oil circulates with the refrigerant. Although the refrigerant will leak out as a colorless, odorless gas and be invisible to sight it will leave an oil trace. Electronic leak detectors can detect leaks as small as .5 ounce per year. If the leak is large enough it can be detected with simple soap and water which will form bubbles at the leak point.

I have the same problem with the same older model, and have kept the coils clean. I've reached the clockwise limit of the freezer control. I wish the answer were that simple. I'm hoping that the oppressive heat and humidity here (Louisiana) might be a contributing factor, but that might be just a dream, and I'll have to shell out for repairs. Still cheaper than replacing it though.

This component is a heating element located on the evaporator coil. When the refrigerator or freezer switches to the defrost cycle, the defrost heater is turned on to melt the frost in the compartment. Failure of the defrost heater causes failure to defrost.Test the element with a VOM set to the RX1 scale. To gain access to the heating element, remove the compartment's wall panels. Clip one probe of the VOM to each element terminal. The meter should read between 5 and 20 ohms. If it doesn't, the heating element is faulty and should be replaced. Replace the heater with a new one of the same type and electrical rating. Connect the new heater the same way the old one was connected.
