The defrost water drain in my freezer is always freezing up. I have checked the drain line many times and it is not stopped up, but every 6-8 weeks my freezer is frozen up and water is running into the frige section. What do I need to do the fix this problem?

The first answer Katherine correct one with one exception; you do not have a problem in the defrost system because you are getting water from the defrost. You may have a clogged (and now frozen) drain, or a faulty defrost heater which supposed to keep the drain from freezing up.
Defrost the drain with hot water and make sure to test running water through the drain down to the drain pan. If it freezes after you cleaned it, replace the DRAIN heater only.
goodluck

yes the drain is in the rear of the freezer ..you will need to remove the covers on the bottom and the back to see the drain..remove all the ice buildup on the bottom ..then use hot water to thaw drain...the reason for the line freezing up is freezer is set to cold freezing leftover water from defrost..let me know good luck/joe/

I had the same problem. The fix was to remove the freezer baskets and defrost the trough behind the back panel wall at the bottom of the freezer section with a hair dryer. This trough takes melted ice created by the auto defrost cycle out the freezer section through a small rubber tube drain into a pan located underneath the refrigerator. My first effort was not successful but the second time I did it it worked. In addition to defrosting with the hairdryer the second time, I also blew out the rubber drain line with a small air compressor. This solved the problem and I have not had a freeze up for the past 6 months.

You will need to install a drain line heater or heat probe. When water is plugged up in the drain line, it freezes and expands. This sometimes destroys the insulation around the drain line, which causes the drain line to freeze up all the time. If you have a cal rod type defrost heating element( black metal element) Whirlpool has a drain line heater, whish is a long metal finger that clamps around the defrost heater and sticks down into your defrost drain tube. This heats up the line every time your refer goes into defrost. We have seen customers use a small length of metal wire to do the same thing, electrical or even a clothes hanger. If your defrost heater is glass,then you will have to figure out how to wire in an electical drain line heater. Ask your parts house to check with GE to see if they have one. Sub Zero has a couple but you will have to figure out how to wire it into you defrost wiring. Good Luck, Appliance Specialists

has the defrost timer been replaced? if not, that'd be the next step. there are only a few parts in that line: the power, the sensor, the timer, and the heating element. also, if the condesate drain is plugged, water stays pooled under the coils and freezes again.

Hi. thanks for the question . The first thing i would do is clear the drain tube .that could be why the freezer ices up .too much moisture Clean the drain, And the coils at the back. thanks the appliance doc

some times low water pressure will freeze drain tube, a badwater valve wont give enough water quick enough and tricling water will freeze ion a a week or so its frozen!

Sometimes what causes this is a obstruction in the drain line. It may be draining, but not fast enough. the water could still be backed up enough to freeze after the defrost cycle. I would clean the line out with compressed air, or flushing water down it. If there is no progress with this, then you can get a drain line defrost heater. they come in all sizes, voltage, and Watts. You should be able to wire it directly into the defrost circuit

check your drain line and check defrost system, defrost thermostat, heater, and timer
