Sealant Choice for wires entering freezer compartment?
Outside air (humidity) is causing condensation in my subzero freezer. The failing putty like material seal that surrounds wiring that enters the freezer compartment is probably the cause. Because of the freezer temperature, what is the specification of a replacement putty? The door gasket has been replaced and seals well.

It is caused by water vapour in humid warmer air inside the vehicle condensing on the very cold windscreen. As long as the interior glass surface is much colder than the inside air it contacts you will get condensation forming on the inside surface.
2. If you equalise the temperature of the air inside the vehicle with the outside temp for 5 minutes before locking up your car you will minimise condensation, as will garaging it. If you drive around with the heater on full on a freezing cold day, stop the car and lock it up exposed, you are going to get condensation, especially if you have used the recirc control to block the outside air from entering the climate control system in the cabin while driving.
3. If you are having this condensation issue set the air controls on the car (before you turn it off and park it) so that outside air can flow in through the cabin venting system. When you drive around constantly with just interior air circulation and no outside air entering you are going to get a build up of humidity.
POSSIBLY faulty door seals allowing outside moisture to enter freezer compartment. This is especially prevalent in older units and/or tropical climate zones [ie high humidity] ... OR if freezer is OVER-LOADED with food items !!!
If you are putting in large quantities of fresh produce to be frozen it is quite often better to PRE-COOL all the items in your refrigerator PRIOR to placing in your FREEZER as they will usually have a high moisture content which will cause frost build-up in your freezer ...
Most refrigerators have some of the condenser coil running through this area to keep condensation down. As long as the unit is cooling fine and it is warm but not very hot there probably isn't a problem. You can check to see if the coils on the bottom are dirty, a cover will have to be removed. Also check to see if the condenser fan is running which is close by the compressor.
The humidity switch does not control the humidity inside the fridge, but rather is used to control moisture that can form on the edges of the fridge and on the divider between the fridge & freezer compartments.
In areas that experience humid conditions, this is a common occurrence. The relative cold of the freezer & fridge in certain areas of the fridge case causes moist air to condense on contact. This condensation is prevented by a heater that is behind the metal case of the fridge. The moist air can't condense because the metal surface is warmer than the room air.
If you don't have a humid time of year, leave the switch set to "off", as the heater uses electricity and lowers the efficiency of the fridge and freezer - resulting in increased cost of operation. Not using the heater when it is humid will eventually cause the moisture to cause rust on the wet areas of the fridge case.
It sounds like the condensate from the drain pan is not draining correctly! The drain tube from your Air Handler unit may be kinked or not properly installed. The condensate water from the unit should be drained outside at least.
2 things:-1)Freezer door does not close completely, leving a gap allowing outside air to come in and te humidity causes water to freeze at the bottom of the freezer. This would explainwhy is forming over 2 days. 2)If your fidge has a ice maker in the freezer and a cold water dispemser, the both these compartments water flow for the ice &for dispenser are controlled by a solenoid valve, which in turn uses a sensor to detect the quantity of water in the ice maker trays and switces off the wster supply appropriately. If the sensor in the icemaker fails to detect the right quantity, overflows very slowly so as to appear to be noticeable..............sdeep
Some units have a selector switch that says; reduce moisture/save energy. If you have this its obvious what to do. If you don't have one or are getting condensation anyway, check the door gasket. Make sure its getting a proper seal. The outside air has water in, aka, humidity. If the unit sucks air from outside, as it cools it will condense and make dropletts accumulate on the top. The drainage from the defrost may also be seeping in and cause the water too. Especially if its on the bottom. It may have a clogged drain line.
