Drain keeps freezing over - Freezers

Use a steamer to blast the drain clear... sometimes you need to install what is called a heat probe that feeds into the drain tube to keep it from freezing over... Help Me Find My Model Number RepairClinic com

Since there is no description of what type of freezer, I will talk generic. Most freezers have some sort of drain heater. Commercial walk-ins use them. 2 types: an insertion type that go inside the drain and another type that is wrapped around the outside of the drain and then wrapped with a foam type insulation call armaflex. hope this helps some.

Try removing the strap holding the drain hose underneath that drains into the pan. Otherwise it acts like a p-trap and holds water that then insulates the upper part of the tube. Condensate water eventually freezes high up in the tube and backs up everything pushing the condensate water into the bottom of the freezer where it freezes into sheets. Leaving the drain hose down keeps air in the tube all the way back up into the freezer area. This seems to keep the condensate water flowing freely into the bottom pan. The air in the open condensate tube does not seem to have an ill affects. Also, you can add some stranded bare copper wire around the heating element just above the drain tube inlet and then push the tail off the copper wire down into the drain tube hole. This helps keep any water in liquid form flowing down the drain pipe.

The problem may be the freezer drain heater has failed, locate the drain inside of the freezer compartment and check to see if it is warm, if not you may need to replace the heater.

I have a coldtech ice freezer 43SLG-L3-JF, the thermostat dial is blank, which way do I turn dial to lower the temp, clock or counter clockwise?

normally when a drain keeps freezing over it is warm food being put into freezer/an air leak in door seals/drain hole could have some moss growing in it(really)or if kept in a garage,the poor thing is too cold.

suprisingly simple,thread a thin piece of string down pipe then tie a button on each end works great for cleaning out drainpipe.....

Not sure of your model number and manufacturer, but in some freezer there is a seperate drain heater that should stay on for the complete defrost time. (the defrost heater will shut off when the evap coil reaches a certain temp, and the rest of the defrost time only the drain heater is energized.) That would be the very first place that I would start. Hope this helps

the drain pipe you cleaned out has a p-trap that holds water. after awhile this trap will build up sludge and possibly freeze up. i recomend defrosting the drain pan again and try some way to forcfully flush hot water thru the drain. I use a turkey baster filled with water to do this. if the drain continues to freeze you may need to install a heat trap to keep drain from freezing.
a heat trap is just a piece of 10-12 guage solid copper wire with about 3 inches in the drain and the other end wrapped around the defrost heater which is the BLACK rod attached to the bottom of the evaporator coil in the freezer compartment. if you need any further assistance just let me know Peyton

thius suggests the defrost system not working and the defrost drain blocked. take off the back panel inside the freezer, melt off excessive ice and free the drain at the bottom with hot water and patience
