Maytag MSD2456DEW icemaker feed tube freezing over

7 posts in this topic

I have a problem with the icemaker on my MSD2456DEW fridge. The icemaker feed tube keeps freezing over. This happened once a couple of years ago, around the time I was running into another issue (which resulted in a replacement of the ADC board, the common flaw on this fridge). About 6 months ago I stopped getting ice, checked the fill tube and noticed it was frozen again. At the time I was too busy to deal with it so I shut off the icemaker and then promptly forgot about it until about 2 days ago when I noticed water under the fridge. Examination revealed that apparently water was still getting into the (frozen) feed tube (at some astronomically slow rate), and over the 6 months had built up a nice ledge of ice behind the icemaker. Apparently it had reached the point where there was nowhere for the water to go, so water started leaking out the back of the fridge where the line for the icemaker enters the fridge. Water was dripping down the line and onto the floor...hence the puddle.

So, yesterday I shut off the freezer and cleaned out the ice from everywhere. As before, I made sure all the lines were clear, etc. Turned everything back on, and voila...after a short time the icemaker dropped its first tray of ice, then the second tray, etc. All seemed well. Went to bed assuming that by morning the ice bucket would be full. Instead, I checked it this morning and the water in the feed tube had frozen solid again. No ice other than the first few trays after I had cleaned out everything.

So my question is, why is the feed tube suddenly freezing solid all the time? When it is not frozen the icemaker works fine--no leaks, feed tube feels properly seated (I always feel the back of the icemaker where the tube comes in to make sure it feels seated in the cup). Or is this some 'feature' of my icemaker--that it makes small cylindrical ice cubes in the feed tube in addition to the half-moons from the icemaker? Is there some valve for the feed tube that is failing, allowing water to sit in the feed tube and freeze?

I always change the water valve in those situations. It's either partially clogged or not sealing properly; either one will produce a slow flow of water; as it passes through the freezer liner, it gets frozen.

Just to confirm: you're talking about replacing this, right?

Part number: AP4071513

Part number: AP4071513

Having never done that particular replacement before, do you have any pearls of wisdom to offer?

Ok, new valve ordered...anyone want to give me any instruction on the best way to swap it? Looks straightforward but I'm always a little leery when it comes to water lines. I'm an electrical guy by training so I generally avoid water. :-)

- Make sure you turn the water off first.

- If your old valve uses the screw on connectors for the plastic lines, make sure you cut them nice and straight before you push them into the new connectors.

- When you reinstall your main water line, be careful to not cross thread it, and do not over tighten it.
