Under the fins inside the fridge there is a tray to collect dripping water. There is a hole at the back of the tray, with a flexible tube going to the outside.

Somehow it stopped draining. No water comes out on the outside, the tray got filled with water, then it froze - I tried to keep freezer at 0F as it should, this required the fridge bin to cool down to low 30-ish. Now I'm checking it every day and manually remove pieces of ice from the tray - VERY awkward under the fins.

Tried to run 1/16 wire through the tube from inside - it hits some hard obstacle within a fraction of inch from the entry. Tried to push wire from the outside - same thing, wire stops after approaching more-less the spot where the tube goes into the fridge back wall. Tried to blow the tube by mouth from the outside - nothing, air doesn't go in. The tube terminates outside with a plastic plug and a tiny hole (to stop insects from coming?), removed the plug, no help.

Tray seems to be glued to the "holed" fitting in the fridge wall, or some caulk, can't pull out the tray to inspect the hole.

There were some dust winds in my absence, but to push the dirt all the way up the tube, and to pack it so hard that steel wire can't go through?

Any suggestions or comments on how to clean the passage or remove the tray, are welcome.

Model N611L, if this matters.

Maybe an electric heat gun. Be careful don't let it get too hot and melt some of the plastic refrigerator parts.

The odds are teh "Hared object" is ice.. I'd start with a full defrost and let it sit warm (Door open) for a day beyond that. After that it gets to be work.


Home was where I park it. but alas the.

The tray is not glued in. Possibly try a little WD-40 where it goes into the wall. Mine ices up occasionally and the plug in the end has gotten clogged as well.

Put a cup to catch any water on the out side drain, then let it defrost completly on the inside. If you find no water in the cup then you probably have food/dust plugged in the drain hose. If you can find some compressed air to blow out the drain from the outside, this will usually work

Good luck
Mike

Norcold drain tubes have a plastic check valve at the END at the drain cup. Just remove the check valve and clean it out. reinstall after cleaning. Doug

Sorry, saw you have done this. IF the tube is blocked, the ONLY way to fix is to pull the refer. Have you had the Cooling unit replaced? Did it drain previously, and the problem just started? I would take a Nylon string from a weedeater and work it up from the outside. Going from inside will not work as the tube makes a 90 degree bend just after it goes to the outside back of the refer hole. Now to your ICE and freezing. The temp setting has NOTHING to do with the freezer. Your freezer temp has NOTHING to do with the ICE in cup or evap fins. Refers, the FIN temp will be 10 degrees COLDER than the interior temp. So if your refer is operating at 36 degrees, the fin temp will be 26 degrees, hence the ice build up.

Thank you, people. Likely the ice. Can't defrost it now, fridge is full. Will have to clean the tray daily so that it wouldn't overfill.

Doug, will all due respect to your knowledge in this area, ice on the fins and in the tray is related to freezer temps, albeit indirectly. Thermostat is in the fridge as I understand. It cycles when fridge temp rises to whatever the thermostat is set to. In warm weather with sun shining on the fridge side of trailer, I have to set thermostat to Max to keep freezer below 4. This causes fridge to cool below 32 and freeze water in the tray, and sometimes to grow an impressive ice fur on the fins before it starts dripping to the tray.

As Doug suggested, remove the check valve. Then maybe try pouring some hot water in the tray. Might melt the blockage.

Sorry, It does NOT. The sunny problem you have has to do with the sun causing problems with convection air over the cooling unit coils. The freezer will get below 10 degrees(normal temp is zero to 10 degrees) regardless of 1 to 5 on the temp adjustment. What you need to do is install an extra cooling fan. If you have a standard 2 door Norcold, it may NOT have a external cooling fan. IF the refer is in a slide room you DO NEED a additional cooling fan blowing out the top access door. Post Year model and Model or Norcold. Doug
